I have just built a new computer, specs:
Ga-K8nf-9 Mobo
X2 3800+ Processor
Asus eax800gto graphics
4x512mb Ram Transcend Pc3200
160gb seagate 7200.7 hard drive
400w Fortron Green Power PSU
Winxp pro
all latest drivers
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.
Can anyone offer any help? thanks.
