I really, REALLY need your help. I bought a new computer last week - Celeron 566MHz, 192MB DIMM, Tyan Trinity-450(S2507S) mobo and a GeForce 256. I put it all together by myself.
The problem is that my video card locks up my computer while still in Windows 98.
I tried to fix that, so I got on the Internet and searched, read and tried almost everything I could find that is related to GeForce problems and crashes. The problem here is that none of the stuff that I've read says something about GeForce locking up during a Windows Installation, Linux installation or while running Windows 98 or Mandrake Linux 8.0 ...
I tried taking out all other cards from the motherboard such as LAN Card, sound card and I left only one stick of my 192MB RAM, to see if it's a IRQ or power-relate problems, but it's not.
I opened the case and left a BIG fan blowing right on the video card...no effect at all...
Then I installed Windows 98 on a formatted HD with the GeForce 256 card in, but I couldn't finish it since my computer locked up either at the beginning of the installation or when the actuall copying of the files starts.
I have also tried tweaking the BIOS settings, but there was no difference whatsoever...
I have found that when moving the mouse my computer doesn't lock up immediately.
Installed the latest drivers from NVidia, but that doesn't really matter since my computer locks up a little after Windows starts up.
Right now I'm using my old video card - Cirrus Logic 5446 PCI and it's working properly...
I installed Mandrake Linux and it locks up too. I haven't been able to run any games except Need for Speed 2 and I was moving the mouse throught the game loading and stuff, but after a few minutes of "playing" and moving the mouse at the same time the computer locked up again...
My mouse is a Microsoft IntelliPoint mouse.
The video card is AXLE Geforce 256 32.
I do not live in the US, so I cannot return the video card to the company I bought it from, they just won't accept it.
Here's my configuration again:
Celeron FCPGA 566MHz
Tyan Trinity 450 (S2507S)
2,5GB Samsung HD (getting a 20GB in a few days)
Philips 32x CDROM
Yamaha YMF 724 PCI
RP-1624W Serias Fast Ethernet Adaptor
A tried the same video card on a different computer with a different motherboard and it worked without any visible problems, lock ups etc.
So I guess the problem comes from the motherboard itself. I could find any information on this, so I'm asking you for help !
