opengl crashes showing white screen???

Exactly as the subject states…all of my games were working fine till suddenly when i try and play any opengl game my computer just crashes randomly showing a white screen and i have to press reset cause nothing else works…ive looked for solutions in loads of forums including this one but with no luck…the most popular solutions being:

1.’;DVA=0’ in win.ini but i have no ‘DVA=0’ in the file…
2.opengl32.dll is there and seems to be fine…
3.all IRQ’s are where they should be…
4.bios settings what they should be(this includes ‘appeture size’ and ‘AGP speed’)…
5.I have updated every driver ive ever heard of for my hardware…

Tried Them All!!

Ive formatted my HDD countless times and still no luck. Most people in this forum seems to have found a solution but none of them help me…

Specs:
AMD Athlon 1Ghz
Chaintech 7AJA motherboard(latest bios)
Via chipset(4in1432v)
448MBram
2, 20gig western digital HDD’s
Aopen DVD&CDRW’s
Creative Geforce3(Nvidia’s 12.41)
SBLive!
LT winmodem
19"monitor
Cluttered desk & sticky keyboard lol

Any help would much appreciated…
