Tried installing a new Gforce 256mb DDR 4x - 8x AGP video card on a PC with PC400 Motherboard and 512mb SDRAM 4X AGP now the machine doesn't boot why?

Boot back with original card, go into motherboard Setup and put all your AGP settings to conservative - ie: AGP 2x, AGP Fast Write off, etc. Now put in new card and see if it boots. If so, play with AGP settings one-by-one (ie: change one, reboot) to get maximum speed without crashing system. Also consider upgrading the motherboard's BIOS and double-check power connections. Double-check if the new card has a power connector on it. If so, it must be connected.

What is syncytial formation?

A general term for any kind of cell that fuses with adjacent cells to form a multinucleated large cells with fused cytoplasms

Virtual Memory refers to your computer's swapping of data currently in use between what types of memory?

We load our computers with so much runtime JUNK that RAM (Random Access Memory) can quickly be used up. All of the little applications that we think are cute, special or "OMG, I just CAN'T live without it", take up memory... but most of those little applications aren't really active at any specific point in time.

So:

the operating system determines what processes aren't currently active, "swaps" them out to a special section of disk that has become known as "virtual memory", allowing that memory space to be freed for something that actually needs to run... NOW.

Virtual means, "sort of but not really", so virtual memory acts like memory... sort of, but it's not really memory.

Disk swapping (that's what happens when the computer gets busy moving memory out to disk and moving "VIRTUAL MEMORY" back into memory) takes quite a bit of computer overhead and is responsible for slow running computers. Many people think their computers are old and worn out because they are running slow, but in reality, they've just accumulated a lot of junk that's running in background, and that junk holds onto memory, forcing more disk swapping (caching) that results in slower running computers.

There are two solutions to the problem:

1. Get more RAM (Random Access Memory) that fits and will run in your computer.

2. Get rid of some of the junk and useless programs that are loaded on your computer. I once worked on a lady's computer that had 36 copies of some spyware and each copy was reporting back to "the mother-ship". All that memory overhead and network communication brought the computer to a halt. It took her over 5 minutes to load a page. After I cleared that junk off her computer, everything ran like new.

How many computers have problems each day?

theoretically every computer has hundreds of problems each day but about 90% of those problems are resolved automatically by the O.S. and other software. for instance when your hard drive drops a sector you don't even know it due to the systems ability to migrate data to a safer location on the disk. so when you ask "how many computers have problems each day" the answer can be simply put as all of them.

Making a non wireless desktop into a wireless desktop?

If you already have wireless internet at home, buy a "pci wifi card" on eBay or somewhere, install the software if it is provided (should be on a cd), turn off your computer, open the case (there should be either a screw holding the side panel on (if it is a tower format) or a button on either side of the computer (if it is a desktop format). You should see a row of white (usually) slots on the motherboard, a metal cover on the side of the case behind each one. Pick a slot, unscrew the cover and push in the wifi card. Screw in the card with the same screw and in the same place as the cover. Close the computer case, turn it on and it should install itself. Alex

What is the difference between a VGA and AGP graphics card and slot compatibility?

VGA is ("Video Graphics Array/adapter") the term for a video card or other video adapter (such as an integrated one). AGP is a standard for video card expansion slots. Basically these are slots (designed for graphics adapters) that operate at a much higher throughput than PCI slots (normal, shoter, usually white expansion slots for other expansion cards). These come in a few versions: 2X, 4X, and 8X are the big ones right now. If you are interested in upgrading your video card (or lack thereof) you need to know what version your motherboard supports (an old one might support 2X /4X) and then you can decide what version of AGP to look for in a video card.

also note that there is a new standard for video cards called PCI-express (PCI-x16). Currently, most of the newest video cards and motherboards are designed on this.

Why is it Laptop HP Packard pavilion when switched on says'error detected' and switches off again Anyone got a clue?

it probably says more than just "error detected." that information and the color of the screen would help in diagnosing this

What is meant by registered DIMM and unbuffered DIMM?

Registered memory improves signal integrity (and hence potentially clock rates and physical slot capacity) by electrically buffering the signals with a register, at a cost of an extra clock of increased latency. Those modules are identified by an additional R in their designation, whereas non-registered (a.k.a. "unbuffered") RAM may be identified by an additional U in the designation. PC3-644200R is a registered PC3-6400 module, PC3-6400R ECC is the same module but with additional ECC

As far as I know, they are compatable. My mother in law lives in Poland and my flash drive works in her computer, also I have had various USB devices in Thailand, Laos, Bali and they all seem to fit and function properly.

Which has the highest data transfer rate USB or IEEE 1394?

IEEE1394 or as Apple calls it, "Firewire" can carry more data. And superior to both of these is Thunderbolt also developed by Apple.

What is a multifunction device?

A multifunction device is a single piece of equipment that looks like a copy machine but provides the functionality of a printer, scanner, copy machine, and perhaps a fax machine.

What are bus lines job in computer internal component?

Buses in the computer exist to carry signals between electrical devices. They are called that because the number of traces that close resemble bus bars in an old telephone relay. There are different bus technologies. Some are parallel, and some are serial and perhaps even compressed.

Why won't my external HD work?

There are many reasons it may not work.

  • The drive could be defective (broken)
  • The correct drivers are not installed
  • Not connected correctly
  • Not compatible with your operating system
  • Not compatible with the motherboard
  • Needs to be formatted

What is the toll-free number for the Toshiba laptop support department?

Yes there is, the toll-free number is 1-800-457-7777 or non-toll-free 1-949-859-4273. This is for the support center located in US. If you need other countries then calling those numbers and asking for a transfer would be a good idea.

What do you mean by input and output devices?

An input device is a piece of hardware that you put data into the computer, such as a mouse or keyboard. An output device is something that the computer controls to output data, such as the screen or speakers.
