How do you rollback a Windows Vista Computer?
If your computer had Windows XP on it and you upgraded to Vista, I heard you could call Microsoft and tell them how displeased you were with Vista and wish to downgrade back to XP. They will then deactivate your Vista Product Key and give you a XP product key, you will also have to have a Windows XP cd.
Megabytes and Gigabytes.
1024 Megabytes = 1 Gigabyte.
The computer has L2 Cache on the CPU. this is very fast memory that cannot be changed.
The other type of RAM (Random Access Memory) is Main Memory, which is in "sticks" on the motherboard, usually 2-3 inches from the CPU. this memory is supplied in (DDR2):
256mb; 512mb; 1gb; 2gb; 4gb.
How do you format a blank hard drive?
If you mean "completely erase" it, the term is "Format" and you can perform it from DOS using the command "Format c:".
I think it is beyond formatting. I read today in the New York Times that John Jay College in NYC has adopted a program that covers the free space with zeroes.
The program your probably talking about is evidence-eliminator.com. This program erases all forensic evidence that remains on your hard drive after you format it, and believe you me it's alot. You can recover the entire contents of a formatted hard drive with the right tools. But EE prvents this and effectively "Zero's Out" you hard drive.
Formating a hard drive prepares it for use and deletes previous file names so Windows can't see them. They still exist and can be recovered with several Undelete programs. However, if you wish to remove all data from the drive, just formatting is not enough. "Zeroing" a drive rewrites over the entire drive, replacing previous data with simple 0's. There are several 'Zero' filling programs available on the web and some drive manufacturers include a zero utility on their support sites.The previous answer is pretty good, however it is argued that you can recover a zeroed hard drive. It is possible to retrieve "some" data however "fully recovering" a zeroed hard drive hasn't been done as far as i know.simply doing a "1 zero pass" will invert all the "1's" to "0's" (remember there are only 1's and 0's) hence "zeroing" however there is software available that can detect newly magnetized "0's" it simply re-inverts the "0's" to "1's" if you do a "7 zero pass" it's pretty much impossible to retrieve any information off the hard drive. look into the "DoD 5220.22-m" standard or "gutmann".hope this is useful.How do you restore aspire 5315 to factory settings?

How do you find and download drivers for your mother board?
There is no such thing as a "motherboard driver." Motherboards are composed of several components, each of which needs its own driver. The drivers needed for the components can usually be downloaded from the manufacturer's site.
What is the best way to troubleshoot a computer that freezes?
Normally there is no way you can stop this but the best way is to just switch it off completely and at the mains and leave it a couple of minutes and then switch it back on. Hope this is helpful!
Why is computer programming necessary?
For a computer to do useful things, it has to be told what to do. That is where computer programming comes into play. However, computers require complex sequences of electrical signals which are difficult to learn and would require constant use of reference books. To simplify the process, you would learn a more human-friendly language, and a compiler converts what you type into the opcodes that represent these complex electrical signals. Then you would run a linker or similar build tool to add the required finishing touches and resolve all dependencies (references to other code and functions).
How do you get a usb Flash drive read as a CD?
A flash drive is not a cd and therefore cannot be read like one.
It is a program that restarts your computer. It sounds like you may have a corrupted program on your computer that is causing the problem. This happens for many reasons . It happens most often during reloading of programs and may have happened at the factory. No way of knowing for sure.
I would suggest doing a systems restore. This should be already on your computer.
If you do not know how, contact your ISP or computer manufacturer and hey will instruct you on what to do. Your computer should me under warrantee and while it is this service should be free.
ANSWER:
Let's ask a few questions before we can isolate the issue. First, how long have you owned your computer? (Is it new? Have you had it for a few years? Have you been doing your updates as they come in?) Second, did you add new hardware? (if you did, was it a communications device? IE: network card, wireless card, modem.) And further, did you use a PCI slot that wasn't the last in the chain? (The very bottom of the board, or close to the video card?) And lastly, did you install a new memory stick?
Now, let's address each of these things.
- If the computer is new and you are having this continual re-boot issue, you should contact the manufacturer for support. If you had it for a while, go to the next step.
The most current updates that can, and have regularly, caused the issue you describe are the service updates, or "service packs" for Windows XP Pro or Home. (Mostly SP2) The registry and MBR (Master Boot Record) are not re activated correctly due to a bad downloaded .EXE) In this case, there is only one thing to do. You must remove or uninstall the service pack. Both, SP2 and SP3 have an uninstall program, and it can be performed through the "Add/Remove" tab in the "Control Panel" Since the computer won't boot beyond the initial bios start-up, then you will need to keep your finger at the ready to hit F8 so you can enter "safe mode" (pressing the F8 key on your keyboard repeatedly during the bios startup.) If you are successful, then navigate your way to the Control Panel and then to the Add/Remove tab. simply remove the service pack, and reboot the computer. The original condition should be achieved at this point, and you can try to let the Update site try again, or, you could just go to the Microsoft website and download the service pack manually. Because of the length of the instructions, go to: http://support.microsoft.com/kb/875350 Here you will find the instructions to help you remove the SP in several different ways. (I recommend you go straight to the last one since you can't boot into windows.)
- Almost all mainboards now, have sound and network cards "built in" and are not required to have add on cards. Most of the new system architectures of today have a specific slot in which to install a communications device, should the need for additional or replacement cards to be installed. They are "Electronically Keyed" as are the new cards, so that the communications device can only work in the one "slot". (This has to do with the addition of the PCI-E bus in the newer systems.) In most systems, the location will be at the last slot on the board. (The furthest away from the CPU.) Some manufacturers have been gracious to color the slot "orange". Soon, it will become a standard, but until that day, currently, most manufactures enter this vital information in their manuals as a side note. Not fair to the most of us, but hey,,,it's their thing….for now! The result of installing the communications card in the wrong slot will yield the problem you have described. In some cases, the computer won't even start. (The board, power supply or both will detect a voltage variant and prevent the startup to prevent damage to the board and interface.)
- And lastly, with the advent of DDR2 and the PCI-E boards, there are some issues with memory and the types being used. Some boards have color-coded memory slots. IE: if you have three or more memory slots, (4 is the most on most boards) 2 will be the same color, and the 1 or 2 if there are 4 will be a different color. This would indicate that a.) if you are running two "like" sticks of memory, they should be installed in the same colored slots, leaving the 1 or 2 slots empty. (Even if the board has a "blue-black-blue-black" you would only use the "blue-(empty)-blue-(empty) configuration.) b.) if you are using size different sticks, then the slots "color code" would be used. IE: if you have two sticks of 512mb and one stick of 256mb then the two 512's would occupy the "blue" slots, and the 256 would occupy the "black" slot(s) This also applies to the "FSB speed" (Front Side Bus) of the memory. Ideally, two sticks that are of a different speed, (yet the board supports both speeds) then you would segregate the speeds in the corresponding coded slots.
In summery, there are several things that could cause the issues you have described. Check each one, and see if any of the suggestions mentioned here, could be a resolution. At the last ends, take your computer to a qualified technician, and have them fix it for you.
How do you load the printer with paper?
It depends what printer you have. All printers are different. A Deskjet 970 cxi just has you insert paper at the tray underneath the top tray that can pivot up and down (where the paper comes out).
How does data on a hard disk determine the speed of a computer?
It doesn't actually change the speed of the computer, but it can change how fast the computer 'feels' because while the PC is reading/writing from the hard drive other things are slower. The longer the data takes to read or write, the slower the computer feels. Because of this faster hard drives are often part of performance class machines.

CMOS is a small component cluster on a computer motherboard which hold a very small amount of simple information. It has a large button battery which supplies the needed power to preform one of its main functions: Keep date and time. It also holds vital system settings.
Basicly, It is a small memory componant, but users can not store data on it aside from system boot settings.
How many cores can a computer have?
Computer processor cores come as single core (one processor), Dual core (two processors), Quad core (four processors) and Six Core. Although apple now offers a computer which can have 8 or 12 cores
How do you reset a PC that will not turn on?
That's vague. I'll try to answer several possibilities. if it would not turn on, and you removed the battery, and you pressed reset, and then reinserted the battery, and attached the battery charger/power adapter, and the AC power light comes on, and then you pressed power, and it still won't come on, and you also tried to power on without the battery installed, running on just the charger/ adapter, *then, your laptop has a serious problem.
Can you use a 65w ac adapter for a Thinkpad T500 instead of a 90w?
According to Lenovo, you can use a 65W AC adapter for T500 models equipped with integrated graphics chips (Intel graphics). If you have the discreet graphics chip (ATI graphics), you should use the 90W AC adapter.
How do you determine if your system is set to boot from a CD or floppy disk?
