My Computer restarts alone

[Lord_Sidious]

Sometimes, I'm very well in my PC when suddently it restarted. Usually that happend when the internet connection was lost. But now it happens constantly!!!
Is this a virus or spyware?
(my norton and my antispyware don't detect nothing)

It could be a heat problem. You should check to see if the fan over the cpu is working properly, plus make sure that the heatsink is not clogged up with dust.

yes zakharov is right, if you didnt changed nothing in software (and anti-virus and anti spyware dont find nothing) is more likely to be hardware. Try his suggestions (and do a global clean too). If dont work try to test memory (with memtest or something like that)

I had the same problem except the restarts would be triggered by something while I played FS2004. I just quit playin' it and never had any other problems.

Your's sounds like a heat prob, like others have mentioned.

It could be the cassandra or virtuamod virus... they call to the LSP layer when being detected or removed by an anti-virus.

virtuamod just usually shuts down the scanner, but cassandra will reboot the computer.

If you have a multimeter you could try checking your psu voltages. Anything out of the norm would indicate a dying PSU, which would cause spontaneous restarts.

This sometimes happens to me when I want to shut it down, but it restarts instead. It never does it twice though, so I ignore it.

I used to have same kind of problem with my older "computer".

I believe the reason for the autorestarts I encountered, were due to the electric peaks that came from refridgerator's compressor. I live in a old block of flats from 50's, and the electric and phonesystems are from that age (no grouding etc., small flames strike from sockets during thunder etc. ) The lousy machine couldn't cope with the enviroment. After I had to buy my third harddisk, when previus two were destroyed in this process, I got a new "machine" which has survided several years working 100% and provided me my civ-experience! It was my friend's 100mhz athlon pentium, which was "ruined" by the postoffice, pouring a tank of ink on it...

You will probably find your new machine has a psu with surge protection, but your old machine did not.

Sounds like your cpu cooling fan is fried... it will overheat when you are asking it to perform...the pc will shut itself down to cool off to prevent damage.

Could also be a bad power supply. SiSandra is a good program to diagnose with - not sure of the link...do a google search ... I beleive they have a 30 day shareware demo that is downloadable.

That happened to my old one when my fan stopped working. (during mid-summer, too)

Me too! I actually had a big room fan setup next to my pc with the case off to try and keep it running long enough to get on the web to order a fan! Sad to say it didn't work.
