My PC keeps turning itself off- power cuts out with no warning, it reboots until it happens again...

any advice?

Mine was doing this, i found i had a virus. :s

how old is the PC, I found this was happening to mine and it was because it was overheating, took it apart and cleaned out the fan and it was fine, fan was getting clogged up with dust and crap

Also, my AVG Antivirus has stopped working .
Currently awaiting on-line technical support

yeah im thinking more and more you might have a virus!
AVG is good but not as good as some otherss.

Mine was turning off because my xbox told it to.. go figure!

Check the above out first, then think about a dodgy power supply or, possibily but less likely, a faulty power switch.
Some clever virus programmes will nobble the common antivirus products - I had one that killed VET a few years ago.
You could try disabling or uninstalling AVG, then downloading another antivirus product like Comodo Internet Security.

In the last few days I've found Ad-Aware and Malwarebytes are unable to access Internet updates, but a malware sweep with a-squared has found nothing on my computer.
So, I'm wondering if their websites are under attack. I'll check again daily.

about to go home & pull the PC apart- gonna make sure the fan is working & it's not overheating. I hear something shutting down (fan?) & PC switches off randomly.

that could be it also Punky I have a laptop that did exactly that when it got a little hot. Problem sovlered by jacking it up on some empty CD cases gave it enough air to survive

Mother Board's gone Punk.



Needs a re-build/upgrade...

i had this pop up come up last night saying some of the windows files original files have been replaces.

please insert the windows cd with service pack 3 in to re install the original files/programs..

i didnt have the cd... im assuming this is a real bad thing

i did a virus scan etc but nothing came up... and i only go on like 3 sites really...and dont download anything so dunno how i would fo got a virus etc?

i deleted AVG (which I paid for ) & replaced it with Avast!
I don't seem to be having anyproblems with my PC.... but I did also move & clean the Box-placed it on my desk where air flow will not be restricted (it was where I had it bfore, but only became an issue recently)

Are there two RAM sticks or just one?

If two - take one out and try it.
Then try it with the other one instead.
