Helping people with computers... one answer at a time.
Read the article that everyone's commenting on.
I had comodo firewall 2.4 on a work computer on a network and it started rebooting without warning (even when the pc was unattended). When rebooted the pc would say that it had recovered from a serious error. I removed comodo and no more reboots.
I remember reading this article last time for Windows 98/ME/XP. Now I have Vista and it all still aplies. I have been able to narrow down my memory/drivers/CARDS/internet explorer/ and just about everything else....
I opened up the case and looked around and found that the CPU Fan power cord was loose. AKA the reason for the shut downs. Thanks to you, after reading you article here I poked around and found this. Gateway="on purpose eat your computer up." Actually probably just a distraught assembly line worker. I have a GT 5432. So far so good....
Still thinking of the 500 watt power supply though.:-)Again thank you for some common sense in a typical problem.
After trying all of the above, I realized IT WAS THE POWER/RESTART BUTTON WHICH WAS BAD!!! SIMPLY DISCONNECT FROM THE MOTHERBOARD TO TEST IT.
I didn't see any mention of this but just as you should have anti-virus software installed and running, do not run two AV programs at the same time. That is guaranteed to cause system problems.
Also a common cause for random or multiple rebootes are defect capacitors around the CPU. (See http://www.elko-verkauf.de/html/schadensbilder.html)
This capacitors have to be replaced.
If you know someone with some experience in soldering, or you can do it yourself, it is a cheap repair.
Had similar problem on my laptop. It was overheating. Blew out the dust and it got a lot better. Have to do that every so often. Also defragment your hard drive to keep things running smooth.
Hi Leo! Gud Day!
I hav a problem to my computer.. it seems when i turn.on my computer by pushing the Turn.on switch.. it Restarts after 4-6 seconds..? I hav already check all the possible reasons that may cause my computer from restarting... there are time that when i fix it, it goes back to normal condition... after a few days.. that problem returns again from turning it on.. wat should i do?
Nick. The problem you are having is a faulty power button. Simply replace with a new power button and your problem will go away. It's a very inexpensive fix.
Your power button is sticking when you press it. When you hold down the power button on any PC for 4 seconds, it will force a shutdown. It's a feature that is used to shutdown a computer that has had a fatal crash and isn't responding.
Leo. I have external fans running on my PC which appear to keep it cool for now. My computer restarts itself only when I use it. That is....if I leave it running day and night without actually using it, it will stay on. As soon as I browse or begin to open up files or emails it starts to restart over and over after a few minutes. Likewise, as soon as I leave the computer it stops restarting.
If it was the fan causing this it would happen all the time wouldn't it?
It's like it's possessed.it knows when i'm there.
