whenever i try to run 3dmark05, 9 out of 10 times the computer will crash. Sometimes it reboots, other times the image freezes or lines appear. The same happens for most games. Even on battlefield vietnam, it crashes as soon as I reach the menu screen. Everything just freezes.
When i check voltages with speedfan, everything is fine except for te +5v. It is fluctuating between 2 and 5 volts. I am sure it is not a PSU problem, because I have already bought another one (the fortron) to replace my original 420w one and the voltage is still changing like that.
I hooked up both the fortron 400 and the orig 420 to my old comp, and voltages are rock stable.
So would this mean that my motherboard's voltage regulators are fried?
Also, the graphics card i have does not have an external power connector, could it be drawing too much power from the motherboard?
My RAM is fine, ran memtest for about an hour to pass through all the tests once.
Another odd thing is that the nforce4 chipset seems to be getting very hot, reported 70C in speedfan. The heasink almost burns when touched. However, others have reported this problem and their setups seem to work fine regardless.
**edit - the problem could also be the graphics card itself..i tested it on another comp and it crashed when loading windows.
Hard to say without playing with it myself (immm ) but it may be the nforce4 chipset which seems to be getting very hot that could be causing the crashers
try adding a fan nexted to it to kewl it down or even use a big house fan and leave your case open just to see if it makes a diff.
then at least you will know if its a heat problem.
i use to have a heating prob. with my card then i found a place in the bios to change the fan settings and it worked fine after that.
Maybe is your display driver. Does it says error or the blue screen of death? nv_disp.dll error maybe? upgrade motherboard bios and driver. In the bios screen set everything to default and enabling dual core and core id.
Is there any beep or sound when it crashes?
Could be ineffecient power?
Direct X 9.c
does it play fine with games and other 3d application or it just happens during high load?
