Computer problem: reset at random

[wautd]

I got this problem for quite some time now and I'm getting sick of it.

The symptoms:

- The resets are random, wether its during a windows session or playing a game, I suddenly get a black screen with a "no signal" on my moniter. The PC than resets. It can be after 5 minutes after I turned the comp on or after 5 hours. Completely unpredictable

- A lot of resets during startup. Sometimes it resets like 20 times before it finally opened windows. Sometimes it still resets after that tough. You can hear something isnt starting up (when it does, it makes a distinct ventilator sound).

- When the problem occurs, its usually for a few days in a row. After that its back to normal for 2 weeks or so before things repeat themselves again.



Now what the hell is causing this? Bad video card? Mobo? Power supply?

Sounds like the video card just went kabomph, which explains the 'no signal' message on the monitor. I have something similiar going on, but
it's the damn power supply causing the random resets.

Sounds like a heat issue, look inside, dust out the case, and look when it boots, ALL fans should be working.

The 'No Signal' is your monitor saying that your computers reseting, this is normal. What your problem is is you power supply is going in the crapper and/or you have a heat problem. Listen for odd noises coming from your power supply/heat sync fans. As well, keep a nose out for ozone as that is never a well boding sign. Past that make sure your heatsyncs are properly on their appropriate chips, the fans are running (clean them if dirty), and download a free system monitor that will watch the temperature and voltage of your system to see which is spiking/plummeting.

A heat issue wouldn't be this intermittent; it would be regular, and occur whenever the temperature got too high.

This definitely sounds like a power supply issue.

Possible. But it's also worth checking the event log to see if Windows left any helpful messages as to what happened at the time it went down.

[wautd]

I forgot to mention (since it been a while), sometimes it also resets after the slightest bump against the case).


Anyway, I'm thinking also power. Gonna check the fan the next time it happens

Bumps? definetly power, check the PSU and the cables, look for worn out stuff or fried shit, if its not cables its the PSU.

This has helped me too. I just helped my father set up his new computer and it was resetting constantly but after checking this thread I found out it was the cable.
