URGENT!!! Computer is very likely jacked up.

Specs: Windows XP, 2.80 GHz / 1024
Hello, everytime i turn on my computer it just sits there on a black screen ( nothing happens) it doesn't even show the bios screen. And sometimes it works. However I have gone through lots of Fresh Windows XP Home Basic Installs. And they all have the same problem. I was thinking about putting linux on it , seeing if it works.Also sometimes when xp boots it gets a bsod. or it says "corrupt files" but if you reboot the "corrupt files" goes away. I have ran 5 full pass memory test. And 2 HDD tests. System specs bellow.

Edit : I had vista installed on this system and it said 1024MB ram, xp says 960MB ram. weird
Edit - 2 : The problem started on windows vista home basic

CPU : Pentium 4 2.80GHz Single Core
SOUND CARD : MotherBoard

What is the make and model of your motherboard?

When everything else fails, read the instructions.

"I had vista installed on this system and it said 1024MB ram, xp says 960MB ram. weird"

If your mboard has onboard video - video built into the mboard - and if you're using that, it's presently sharing 1,024 - 960 = 64mb of the installed ram with the video.
Some mboard bioses display the installed ram total minus that shared with the onboard video in that situation - XP reports whatever total ram the bios displays as the Physical Memory - if you were using the onboard video in Vista too, apparently Vista displays the total installed ram amount in the same situation.
The amount of ram shared with the onboard video cannot be used by the computer user for other data.

It is common to un-intentionally damage IDE data cables, especially while removing them - the 80 wire ones are more likely to be damaged. What usually happens is the cable is ripped at either edge and the wires there are either damaged or severed, often right at a connector or under it's cable clamp there, where it's hard to see - if a wire is severed but it's ends are touching, the connection is intermittent, rather than being reliable.
Another common thing is for the data cable to be separated from the connector contacts a bit after you have removed a cable - there should be no gap between the data cable and the connector - if there is press the cable against the connector to eliminate the gap.
80 wire data cables are also easily damaged at either edge if the cable is sharply creased at a fold in the cable.

Try another data cable if in doubt.

Check your SATA data cables. The connector on each end should "latch" into the socket on the drive and on the mboard, or on the drive controller card - it should not move when you merely brush your hand against it near the socket - if it does, mere vibration can cause a poor connection of it - use another SATA data cable that does "latch", or tape the connector in place.
(There is a slight projection or bump on one side of the outside of the connector that "latches" it into the socket - it's easily broken off or damaged)

The same thing applies for the SATA power connection.

Some mboards develop this problem - electrolytic capacitors were installed on them that were not properly made, and they fail eventually - the mboard manufacturer didn't know they were improperly made at the time the mboard was made.

Open up your case and examine the mboard to see if you have bad capacitors, and/or other findable signs of mboard damage .

This was the original bad capacitor problem - has some example pictures.

If it is not showing the BIOS screen then it isn't Windows (BIOS activates before Windows loads).

Always a good idea to check plugs and sockets but the possibility of a video card issue is also likely. If it is a separate card (rather than onboard video) then take the card out and clean the edge connectors with a pencil eraser. Pop the card in and out a few times to ensure there is no oxide on the socket. It might be worth doing this for the RAM too, despite your test results.

T&W. I think your first link has gone adrift - it appears to go to a broadband website.

We all live on a ball.
