How do you edit favorites file to add delete andor arrange in order?

First, I'm going to make an assumption. I am assuming you are using Internet Explorer (the picture you click on looks like a blue lowercase "e"). I'm also going to assume you are using Windows XP. Now, to do this, given the above assumptions, you will first want to open up Internet Explorer - as if you were going to search the internet or check your e-mail. It doesn't matter what the page says, as long as the window is open. Now, you should see a few menus at the top of your screen that say "File Edit View Favorites Tools Help". If you don't see this, then press the "Alt" button at the bottom of your keyboard and you will. Now, from the words that I just talked about at the top of the screen, click once on Favorites. A menu should come down displaying all your favorite links. Now, click on the words "Organize Favorites..." - it should be the third one down the menu. A new, smaller window should pop up giving you the option to create a new folder, to move files, to rename files, or delete them. -CCMFreak2

What is sleep mode?

An energy-saving mode of operation in which all unnecessary components are shut down. Many battery-operated devices, such as notebook computers, support a sleep mode. When a notebook computer goes into sleep mode, it shuts down the display screen and disk drive. Once awakened, the computer returns to its former operating status.

How does a heatsink on a computer remove heat to keep the components cool?

Adding a heatsink to a component increases the surface area that is exposed to cooling air. In other words the same amount of heat is spread out over a larger area and more air can get to it so the part stays cooler. ==Answer 2, More input == Answer 1 is correct, and my answer is NOT intended as a challenge, but 1 was not responsive in answering the question: The question was "HOW DOES...REMOVE heat...?" Answer 1 explains how the sink gets rid of the heat. The answer to HOW, is--"by CONDUCTION." The heatsink, usually made of aluminium, is very firmly and intimately attached to the component to be cooled, often using a small bolt or screw, or with spring tension built into the construction of the sink. The sink then "draws," in laymen's terminology, the heat from the component into itself. The miniscule "gap" remaining between the two surfaces is resistant to the conduction [transfer] of heat from the component to the sink, so to improve thermal conductivity, a thermally conductive "grease" is applied to the joint before mounting the sink to the component. The heat is then transfered to the sink by CONDUCTION, and by virtue of the sink material, and [as described in answer 1] the greatly increased surface area exposed to the air, the sink releases the heat to the air at a greater rate and volume than the component by itself could.

What happens when a hard drive gets full?

You'll need to boot from either a floppy or a CD, and delete some unused files. Duriing normal operation, the system writes a fair amount of data to disk, and without sufficient free space you won't be able to use the computer. You might need to do a disk cleanup to clear some lost segments. If you can't get enough free disk space you may need to get a larger hard drive and transfer everything from the old disk. Good luck. Usually there is a lot of garbage and unused space available. 1. I presume you have run a program like WashAndGo (http://www.abelssoft.de/ordergo.htm) to tidy up and delete unnecessary stuff. You should also empty the recycle bin. 2. Use Windows Disk Defragmenter(http://en.wikipedia.org/wiki/Disk_defragmenter) to pack the disk. 3. If your disk is still full you need to backup (http://en.wikipedia.org/wiki/Backup)the files on your disk. 4. Decide whether to delete the programs you don't use anymore using the Control Panel's "Add or Remove Programs utility." 5. You may decide you just need a bigger drive. In that case a new hard disk is the thing to get (http://www.pcworld.com/howto/article/0,aid,47370,00.asp). I'm guessing that you may be fairly new to this so before you get too enthusiastic drop by your local computer store and ask someone at the repair desk how hard it is to do yourself; you may just decide to let them do it. Good luck, Carlos

What do you do if you can not defrag a harddrive because there is only six percent space left on the disk?

You are going to have to free up some space on your hard drive. You have too small of a hard drive for the programs installed. Start removing programs you don't need. Next start removing videos & photos. Keep removing stuff until you get around 12-15% free space. Also def ragging in safe mode will help.

How do you change the bulb in a scanner?

You can't. Its a special bulb. Either get the scanner repaired/replaced if its within warranty or buy a new one (they're quite cheap nowadays)

Are all DDR SDRAMs interchangeable?

Yes, but only with other DDR, not SDR. DDR is 184 pins where SDRAM is 164 pins. There are a few factors that will affect the speed of you memory: 1) The memory itself If you buy cheap memory then you might have slow memory. the chip can only move as fast as its slowest memory section 2) Maximum clock speed on the motherboard Your memory will only run as fast as your mobo can run it. If your mobo supports up to PC2700, buying PC3200 will only run at PC2700 speeds

Why wont Mp3 play in your car CD player?

Your player may not support MP3.

Your mp3s may be encoded in a way which is not compatible with your CD player. Many CD players cannot play variable-bitrate mp3s for example.

Sometimes my car stereo (which supports mp3) has difficulty with some of the cheaper CD media. Cds which are odd colors are often not readable by in-dash players.

What are the drawbacks of add on cards?

The only major drawback to add-on cards is that they need to be installed. This process requires the case be opened (powered off and cables removed, label them if you are not sure where they go) and a blanking plate removed. The add on card would then be inserted into the open slot, seated properly and then the screw replaced. If you are uncomfortable doing this, most local PC repair shops will install the card for you. Things to look out for: does the new add on card support your Operating system, and does in have the proper drivers with it. Most add on cards add features, or functionality to a computer, or improve the embedded devices on your motherboard. A good example is that most retail computers have the video graphics embedded on the motherboard. They are fine for normal graphics and web stuff, but if you want to play serious games, a add on graphics card with decent memory is better. Hope this helps.

What is a cache?

Answer:- The Cache memory is placed between the CPU and the main memory. It is a fast speed memory and is expensive and faster than the main memory.

Cache memory is used to store the frequently accessed data of main memory. The instructions that are frequently used by the CPU are stored in the cache memory. It is used to reduce the average access time for address, instructions or data, which are normally stored in the main memory. Cache memory increases the operating speed of the system. But is much costlier than main memory. From economic considerations, the capacity of the cache memory is much less as compared to main memory..

How do you find your usb version?

  • There are only two versions of USB, signified by the throughput of the data. USB 1.1 is roughly equal to 12 megabits/second of throughput USB 2.0 is roughly equal to 480 megabits/second of throughput USB versions only affect the speed, therefore, if you are worried that a purchased USB 2.0 (Hi-speed) device will or won't work on your USB enabled PC, the answer is yes it will, regardless of your USB version. The only "problem" is that it will operate at a slower pace than that of a USB 2.0 enabled PC. As a general rule, PC's that are newer than 2003 typically come installed with USB 2.0 ports. If your version absolutely needs to be known, go to your Control Panel and open up your System Icon and go to Device Manager. Under Universal Serial Bus Controllers it will list all of your USB devices. USB 2.0 devices will be labeled as "USB 2.0 Root Hub". It's important to note that Windows 95 and NT do not support USB. Windows 95 requires OSR 2 in order to support the devices, NT will not regardless of upgrades. -
  • Unfortunately, I know on one of my PCs, a 2 month old Dell Dimension 8400, that USB2 is installed, but it still shows USB RootHUb in Device Manager, not stating USB2RootHub. Looking for a better way to determine USB version!

How do you connect a 5.1 sound system to the 3 audio connections on the back of a computer so without using a sound card?

The 3 audio connectors on the back of the computer are usually - Headphones/Line Out, Microphone, and Line In. To get audio sound FROM the PC only the Line Out is used. This socket provides STEREO SOUND ONLY but can be connect to a 5.1 system using a 3.5mm stereo connector to stereo RCA cable (the RCA cable with red and white ends). These are then plugged into the red and white RCA sockets on the 5.1 system but will only give stereo sound not true 5.1. 5.1 is not available unless you have either an optical connector or a coaxial digital connector on the computer. BTW the 3 audio connectors on the back of the computer IS a sound card, it is built in to the motherboard.

buy this kind of wirelook for a wire with the output end that is the usual one you use for plugging in the normal PC speakers, and the output end like the red and white ends that you connect to the sterio. buy it, and plug it in the right places, and that's it. you got ur PC connected to the sterio system. i have that too, and it works, but it wont give u true 5.1 sound although the quality of the sound is a great deal better! Check your BIOSSome of the built-in soundcards on modern motherboards do support 6-channel sound (5.1). By default those 3 ports may be Headphones, line out and mic, but if you go into the integrated peripherals section in your BIOS menu there may be an option to enable 6-channel sound. Doing so will reconfigure those ports to 3 line outs, front, rear, and sub.

This is not the case with all motherboards and it is very likely that your best option may be to install a PCI sound card, they are very inexpensive.

How do you stop your CD-ROM from freezing?

This could be a number of things. First if it is only freezing while reading your Viso CD, then it may be a CD problem. It could also be that your CDROM is a "cheaper" grade and doesn't read certain types of CD media very well. If it will read other CD's then this is probably the issue. If your Drive responds this same way to all CD's it's very likely that it has failed. If you think this may be the problem CDRW's are very cheap now, and sometimes free if you find the right sale paper and rebates. I would pick one up and replace your current drive. This would be an easy test and if it still exhibits problems, at least you have a new CD Burner now. More input from FAQ Farmers: * CD-ROM's can't just "freeze" by themselves, BUT what could be causing your computer to have problems reading from the CD is a number of things. First, make sure that the CD you are using has valid data on it. I ran into a number of cases where I failed to make a perfect CD-ROM, and my DVD-ROM drive was the only drive that could read the CD after several attempts. Next, make sure that the CD itself is CLEAN. Use a dry cloth to buff the data side of it before placing it in the drive. Do NOT use WATER. Also, make sure that the drivers you use for the CD-ROM drive have no viruses.

What is the difference between an internal and external clock?

AnswerThe internal is located inside your computer. If your running Windows, the time it keeps is display on the lower right side of the screen.

An external clock is usually located on another system and can be accessed with software. You can get software to sync your internal clock to that other system. The National Institute for Science and Technology (NIST) hosts a clock that many computer users and businesses sync to.

Wow...can that answer be any more wrong?

Internal and External clocks are NOT referring to the "time of day" type clocks, they refer to the internal processor clock cycle or an external clock source. The clock cycle of a processor is the time it takes for the processor to execute a data instruction (very basic explanation there) and is measured as the speed of a processor, like a 2.6gHz processor can execute 2.6 billion clock cycles per second.

Now this is somewhat misleading as the processor speed itself is probably only 400MHz, but using an External Multiplier (clock multiplier, external clock), you increase the total amount of data the processor can execute in one clock cycle.

This is a VERY basic example and I don't have time to really go deep, so it's best to search for a more concise answer if you really require one.

What computer hardware and software do you need to set up a credit reporting system?

That I couldn't tell you. But I would say that you should be extremely cautious when engaging in this type of practice. Like the advertisements claiming you can make a fortune running your own collection agency, it's just not true. Many people who try this end up in deep debt themselves via lawsuits. There are very strict state and federal statutes that govern colleciton and reporting agencies. They apply to the "little guy" as well as the large ones.

Where can you find the timing reset button on a 1990 Lexus LS 400?

I have a 1990 LS400 and I have never heard of a timing reset button. The timing is set by the timing belt and controlled by the computer. Let me know if you find out there is such a thing. vbd

Basic instructions are stored on the motherboard by?

The BIOS ( Basic Input Output System) is used to store the basic instructions that are required by the computer to operate. Only critical files are loaded when the system by the BIOS is turned on.
