Ok my computer (mostly) randomly stops, waits 10 secconds, blanks the screen, then ati VPU recover kicks in and everything comes back but i'm unable to do anything 3D afterwards.

I have tryed 2 gfx cards ATI radeon 9000 and ATI Radeon 9250. I have tryed various Bios settings and both the offical ati drivers and the Omega ones.

at the moment with the 9000 in i am even unable to play unreal tournament in either directx or opengl

My computer specs are as follows:

Tyan Tiger T230 Motherboard
2 x PIII 1.13ghz
512mb +128 MB Ram
(Currently) Ati Radeon 9000
130gb hd + 320gb hd

Windows XP SP2

Please assist.

Did you try running dxdiag in a command window?  You may need to reinstall DirectX.

i have before the computer crashes it's fine.

No problems found.
DirectDraw test results: All tests were successful.
Direct3D 7 test results: All tests were successful.
Direct3D 8 test results: All tests were successful.
Direct3D 9 test results: All tests were successful.

After is crashes not even direct draw is enabled.

You've changed video cards, so the problem may be in the motherboard or the RAM.  Try running the memory diagnostic program at www.memtest.org and see if it fails - if it does, you have bad RAM.

Nowadays, monitoring is a mixture of tools, systems, and codes—making it a very complex process. And with this complexity, comes variables for failure. Get DZone’s new Guide to Performance to learn how to proactively find these variables and solve them before a disruption occurs.

The thing about memtest is that if it passes, that still is not a guarantee that the memory is good - only known working RAM will prove that.  A failure does mean bad RAM was detected.

well i know it was a fault chip 1 cause mem test came out with 100000 errors after only 2 mins in to the test and after i removed it i was able to install windows again (which i wasnt able to do while the chip was in)

Did you have a power event or did something else happen that caused the machine to die?

What I'm trying to determine is if this machine was working normally at some point and then it stopped working.  What happened to cause this is a clue as to what is wrong with it.

check if your power supply can handle the load :  http://extreme.outervision.com/psucalculator.jsp      
also check the cpu temperature after it stops, it can be heating up
i suppose all fans are running normally?

A powered USB device should not draw much at all, but if you exceed the 500mA current limit on a USB port with multiple devices, you can crash the system.  What do you have connected?

Well i have changed the PSU but i'm gunna have to try changed the gfx card again as i belive that this gfx card (9000) has issues with my motherboard... i will get back to you with the result.

ps. i don't belive that i was exceding the limit i was just looking for ways of reducing the total load.

A Radeon 9000 does not support DirectX 9 - you need a 9500 or better for that.  Try uninstalling DirectX9 and use DirectX 8.1 instead.
