I have posted yesterday about my problem with restarts in 3 D MARK 2005.
See "PC restarts because of "MODE: GXO Execute BIOS Table Error""

AMD Athlon(tm) 64 X2 Dual Core Processor 3600+
Radeon X1950 Pro
Motherboard AM2NF3-VSTA
Memory RAM 2 GB DDR 2

It seems my problems and restarts stopped after I changed in BIOS AGP from 8X to 4X. I have successfully finished 3 D MARK 2005 few times and I do not see any big fps drop in games.

Can someone tell me please is it OK to change AGP 8X to 4X as I did or it could be bad for PC components?

Sorry for my bad English.

Your AGP slot on that board israted at 8x, so that shouldn't be the problem. I'm guessing you're having an overheating problem somewhere, more than likely it's your chipset. Try changing it back to 8x, take the side off the case and point a house fan at it, and then run 3DMark and see what happens.

Maybe you are right because I am having problems with that motherboard ...
So you suggest I should try to cool down my chipset with house fan? I will try to do that ... but as I remember my graphic card is almost placed all over chipset...

Well my guess is, when you're setting the speed to 4x from 8x, you're reducing the amount of electricity that runs through your board at a given time, thus reducing the heat produced. That's why it wouldn't be restarting. Just a guess though, I could be wrong.

Here it goes! I have run 3 D Mark 05 two times successfully with AGP set to 8X:

1. I used house fan to cool down chipset and it finished normally
2. I repeated 3 D Mark 05 without house fan but with case open and it finished normally again.

So, could it be that high temperature (summer heat) in room is affecting PC cooling so much? I have additional fans in case and don't have place to put any more. Or is all this just random ? I will have to close case again because I can not leave it open all the time so I will see what happens...

If it is mostly due to the chipset cooling, what should I do to cool chipset more affectively?

Try it a couple more times, with the side on and off and see if you can get some reliable results. You need to get some air flowing over the chipset, either by installing a fan on your side panel or getting a case with better air flow.
