after reinstall of Windows my computer exits 3D applications randomly

I have a computer
AMD Athlon 1200/133 on
Abit Kt7A Raid
2 IBM 20GB HDD in Raid 0
1 Quantum 4 GB HDD on 1st IDE master
and CD as slave
256 MB Infinon PC133 Ram
Gainward GeForce2 Pro/450 Grafics
Soundblaster 128 PCI
Realtek RTL 8029AS Network-Controller

it was running fine for about a year now, but I had to reinstall because of lots of changes in system that made Windows slow down.
After new Installation everything seemed fine until I began using  3D applications and Games.
Especially 3D Mark 2001 and Morrowind show following sysmptoms:
after about 2 minutes the computer drops back to Windows without giving any explanation or Error message.
I have tried now:
- Windows98, 98SE, ME, XP
- Via 4in1 drivers 424, 434, 438, 443
- Nvidia drivers  23.11, 28.32, 30.82, 40.72
- updated BIOS
- changed different BIOS settings
- the Graphics-card works fine in an P2 400 System
- the RAM does that, too

I don't know where to look for this error - which components do cause it.
I hope somebody can help.
Thank you very much.

Are the Nvidia drivers the correct ones for your Gainward card? The drivers are probably different for XP than for Win98 SE/ME. Maybe there is a conflict between the drivers for the different OS. It sure sounds like a graphics card driver issue. Search their knowledge base.

It could also be a heat related problem.

have you tried using a FAN on it ?

Have you tried using a different IRQ ?
hat about the vga aperature settings in the BIOS ?

I hope this helps !

Nvidia drivers for 98 and XP are both used according to system.

I have thought of the heat problems, too. But I dont thing it's the heat because
- the graphics card has a fan on it,
- the processor cooler is a Zalman CNPS5005CU
- now at testing the system the computer case is open
- the computer worked fine before.

AGP aperture size is 64M - yet untouched.

I have tried different IRQ settings via changing the other cards in system, adding / removing PS/2 mouse ...
enabeling/disabeling ACPI ...
The IRQs change, but the problem remains

Can be the memory timings are too aggressive.Enter the Bios settings and check the latency timings for the RAM.If the it is 2, see if you can lower it to 2.5 or 3, and test.If you still have problems, lower some of the other settings.I think these will be seen in the second or third Bios entry.

Changed the timings to slowest values - problem remains.

What about the raid drivers for the motherboard? Are these the same ones you were using previously?Check the website for the latest and try those.

Commented:
Hi
Have you tried removing the PCI cards and their drivers?
I would also suggest to try another clean install, and then install only the drivers for M/B and Graphics.
I know it worked before but...

Commented:
I tried the newest Raid drivers first, after the problem occured I used the ones that woked before. No change.
I even tried downdating BIOS and updating again - to flash the raid bios anew....

I tried clean install with Win98 and WinXP
both with only Graphics card and Raid installed.
Same effect...

Commented:
Since the problems seem to be with the 3D applications,then lets look at these:
1) Drivers for video card- try different set of drivers and install Direct x 8.
2) Heating problems- does the motherboard have a monitor that gives temperature readings, if so what are these?
3) Memory problems- if you have more than one stick, try using one at a time and switching.

1) I used Nvidia drivers 23.11, 28.32, 30.82, 40.72 with DirectX 8.1b from different source cds
2) system temperature is about 25°C processor at 49° while case is closed
3) Thought of this, too. checked both sticks seperately with Ontrack data advisor and in my old PII system - everything seems fine.

Commented:
The last thing that can be tried is another power supply as the old one may be getting a bit flaky and during intensive graphics task, it may not be giving a smooth enough output.

Commented:
Sorry, for waiting so long to post,
but even changing the power supply changed nothing.
 
I have found a solution though - I just can't say why it works, but it does so.

I have installed the unofficial VIA latency patch and after reboot everything works fine again.
It is the same with Win9x/SE/ME/XP ...
After latency patch is installed 3D applications work again.

Thank you very much for your help
