I built a PC system about 4-5 years ago. It's been great the whole time, with few problems.
Lately my system has begun rebooting itself randomly. Usually happens about once every 3-4 days, and when it happens it sometimes happens multiple times in a night. By rebooting I mean the entire system instantly switches off as if there was a power outage and then a couple seconds later starts back up again. Probably due to a piece of hardware failing or overheating.
A couple times I got a "Overclocking failed" message on reboot. I'm not currently messing around with overclocking settings on any of my hardware. I'm not sure what this suggests..
I took it to a shop to be looked at. They fixed my hard-drive (corrupt, probably from all the random reboots), and they tested it over night and couldnt' find anything wrong, and checked all the cables.
I'm at my wits end because I don't know how to troubleshoot this on my own, or how to narrow down the problem. It's obviously hardware related. Most likely overheating I suspect. I don't know which component is causing the issue.
Can anyone offer tips on how to troubleshoot this? Is there any way to monitor the individual components so I can narrow down which one is faulty? Is there software that will create an error log? A hardware failure record that can be analyzed or examined? How can I find out what I need to do to fix this?..
Any help is greatly appreciated. If any further info is needed, let me know and I'll try to provide whatever I can.
I would start with a new power supply. Even a used one off craigslist if you can't afford new. The antecs in the 350-450w used are pretty reliable, and I've seen some as low as $15.
I think you're probably right, o1die. I did some reading online about common reasons for systems to randomly shut-down without warning and power supply was #1. I can't say for sure though without any kind of hardware testing, which I have no idea how to do.
I found an old spreadsheet I put together with a listing of parts for the new system 4 years ago. This is what I have:
Asus P5E Socket 775 Intel X38 ICH9R Chipset Dual-Channel DDR2 1200/1066/800/667Mhz eSATA/ 6x SATA 3.0Gb/s 8-CH SupremeFX II Audio 2x PCI-E x16 Firewire 12x USB 2.0
It appears my current power supply is 720W. What would you guys recommend, if I were to buy a new power supply? What are the best brands or models for this system? Is there a simple way I can test my old one to see if that is indeed the problem? Power monitoring software? Or cheap hardware I can use to test with (a meter?)?
