I have a desktop restart issue of late that has me wondering what is going wrong. The system would switch off all of a sudden, but the motherboard LED is ON. On moving my mouse or hitting a key, the system will boot up again (move mouse like waking up from standby). There is no pattern in occurrance.. it just happens randomly.. sometimes continously every 5 or so mins.. sometimes not at all and runs fine for hours.
And once during one of those frequent power-offs I went into BIOS and was monitoring my CPU temp and it powered off by itself even with CPU temps around 50-55C while I was in BIOS itself. So it gets me to thinking it must be a hardware issue. I suspect things in the following order
1.PSU - Maybe it fluctuates just enough to power-off the system. It's a default PSU that comes with Zebronics cabinet..But it reboots itself once I move my mouse.. that makes me wonder if it is due to motherborad issue. Will the system start on a mouse move if the PSU was at fault?? I doubt it.
2.Motherboard - I replaced it recently.. around 2 months ago and it was runnning fine for the first month before this happened. The model is ASUS P5KPL-AM/PS
3.RAM - I suspet this too because when it starts to power-off, I replaced the 2GB DDR2 Kingston ram into the other slot in motherboard and this seems to prevent it from happening... at least for a couple of days..Have been swapping the RAM on two slots for 3-4 times now....
4.Proccy - it's an old Intel E6300 C2D@1.86Ghz. Initially I suspected shutdown due to overheating since I put it on the new board with new thermal paste and thought maybe the Cooler was not seated properly. BUt the temps are hovering around 55C which I feel is normal.
Is there any way to narrow down on what might be wrong? The thing is, its not reproducible and happens randomly, maybe even days apart and I have to source a test replacement each from someone else and it might be more than a month before I am done with my Trial and error...
