Unstable Tyan Trinity 450 and GeForce 256


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
ATX 250W

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 !

  1. That motherboard uses the VIA Apollo 133A chipset. Go to <A HREF="http://www.viaarena.com/?PageID=2" target="_new">http://www.viaarena.com/?PageID=2</A> and download the latest VIA 4-in-1 drivers. Basically, you NEED the VIA 4-in-1 drivers installed for a VIA chipset system to run stably. Do that, and it should work just fine. Also, you may want to go to <A HREF="http://www.tyan.com/support/html/bios_support.html" target="_new">http://www.tyan.com/support/html/bios_support.html</A> and download that motherboards latest BIOS release, and flash the BIOS. That may help clear up some stability/incompatibility issues as well. Good luck and reply back with the status.
