I'm running:

barton xo 2500+
Abit NF7
512 DDR ram
gforce 4 ti4600
adequate fans
power supply is 350W


so far, my computer only turns itself off whilst running championship manager 4. Maybe after playing 5-10 minutes into it, turns off....and it seems to go into standby mode. I can't turn my pc back on immediately unless I unplug the PC from behind.

I've checked the temperature whilst playing the game, and it stays below 60 before turning off. I don't have "shutdown pc if temp gets to certain temperature" enabled in bios.


I reckon it's some kind of inbuilt safety thing in the motherboard? Champ Man 4 runs the cpu at 100% constantly. I've never come across another program that does that. The game worked fine on my last pc though before this upgrade (800mhz, 256 ram, gforce ti4600)

Sounds like another heat problem. Try taking the side of your case off and blowing a fan directly on the mobo. Keep the fan far enough away so the motor doesnt interfere with the machine. If this fixes your problem go by more fans or a better built case.

I have a barton 2500+ and a NF7 V2.0 (to check the version, look onto the little sticker on the mobo itself) and it was having this exact same problem, while benchmarking and stress testing. It would heat up to just under 60 degress and shut down, even though I had the Mobo Shutdown temp at 75 degrees and the CPU shutdown temp at 85 degrees. When I downloaded an updated bios (the mobo is relatively new and full of bugs, so regular bios updats are released all the time) and it fixed the problem. It was apparently a problem with the detection of heat, even though Hardware monitoring programs reported the Temp at the real values, the motherboard's internal safety mechanisms were fed the wrong information. So just go onto Abits website and download the latest bios for the NF7 (or the NF7v2.0 if you have that one) and read the instructions on how to flash the bios (if you dont already know) it worked for me.

well, problem is definitely due to temperature.

I placed my computer on the floor with the side panels open and an bedside fan blowing into it to help ventilation, + I underclocked pc by about 300mhz.

Still heats up quite a bit when I use 100% of cpu, but not as much and so doesnt crash.


I guess I need a better fan. The fan I got gave a specified range up to xp 2500+ which is what i'm using. Quite annoying, i guess they don't expect you to use 100% of your cpu
