Hello,
Any one having any idea that might help me troubleshoot my home built computer?
It has started to suddenly shut down a couple of times the last week, as if the power is suddenly switched off. However, the lights (a red light behind the expansion slots, a yellow BIOS led, and power-on/reset switches) are still on on the motherboard, but nothing happens when I try to start the computer again by pressing the regular power on button (on the case front). To start the computer again, I must first switch the power supply unit's power switch, off, and then on again, and then press the regular power on button of the computer.
The ASUS AI Suite software shows CPU temp of about 54 degrees Celsius, and motherboard temp of I think about 20 - 30 degrees Celsius. The BIOS (version 3404) settings are "Optimized Defaults"(, except for the CPU fan speed monitor, which is off). I have also tried the previous BIOS version, but same result with that.
Is it possible from these symptoms to tell if it might be the power supply or the video card or something else that is broken?
The power supply unit is a Chieftec GPS-350EB-101A, that I have used for about 5 years, 24 hours per day, all year, and it is plugged into the wall directly. The power supply unit sometimes makes quite a bit of noise when the CPU is under heavy load, but not when the CPU is idle. The video card (ASUS EAX550HM512/TD/128M/A) is of the same age (and I have not installed any driver for it on this computer) , but I have not played a lot of games with it.
I have mostly used the computer to analyze chess (=heavy load on the CPU), also when it has suddenly shut down the last week, but it has never been any problem running it for chess analysis before the last week. Now it typically shuts down after 1 to maybe 12 hours of chess analyses, and with the prime95 "Blend"-test, it shut down after only about 3 minutes.
Best regards,
Claes
