Windows 7 restore is very good imo

Re: PC keeps restarting
 

I've now done a system restore and will see how it goes. I'm going to call it a nite and will try again this time tomorrow

Re: PC keeps restarting
 

Good luck!

Re: PC keeps restarting
 

No luck with the system restore. This morning I started the machine before I went to work and it asked me to activate my Windows as it thought it was not legit (OEM purchased when I built the machine) anyway it was happy once I activated it and within 5 mins restarted itself. So I rebooted in Safe mode and ask my wife to keep an eye on it to see if it reboots. If it doesn't then I think I may try a live CD and see if it reboots. I'm also going to give the machine a quick clean tonight as there is a little but of dust but I can also try reseat the cards etc and see if that helps.

This is probably the first thing he should have tried.

Re: PC keeps restarting
 

I had a faulty power swtch give similar symptoms once upon a time.

Mind you by the time I found the fault it had worsened to randomly starting up the affected PC as well as shutting it down.

Nightmare :Yikes:

Re: PC keeps restarting

How do I install memtest to usb

Memtest 1.7 has been running now for 3 hours 40 mins passed 7 errors 0. Its still running should I leave it running overnight? The machine has not rebooted today while it was in safe mode and while running memtest.

Re: PC keeps restarting
 

I'd do a complete fresh install... If it's not too much trouble.

Re: PC keeps restarting
 

The thing is its going to be a real pain. I was hoping it was a hardware issue. How could it be a software issue if it suddenly started restarting itself. I could understand if I installed something recently and it start resetting.

Re: PC keeps restarting
 

Memtest 1.7 passes 27 errors 0. When will I know when the tests are finished

Re: PC keeps restarting
 

it just keeps going until you stop it, so that means it has done a complete set of tests 27 times.

I think as suggested earlier try using a live CD OS for a while and see what happens

Re: PC keeps restarting
 

im sticking with what I said here until tested I personally can offer no more advice

Re: PC keeps restarting
 

I;ve booted up ubuntu 10.04 32bit from a usb and so far its not restarted however its not picking up my drivers for my video card. It asks me to activate the ATI/AMD proprietary FGLR graphics driver and when I do I get this message
Failed to fetch http://archive.ubuntu.com/ubuntu/poo...untu4_i386.deb 404 Not Found [IP: 91.189.88.46 80]

The card I'm using is http://www.ebuyer.com/product/190138

Re: PC keeps restarting
 

I think I may have found the cause. When I startup in safe mode I looked under the unistall programs and I see skype 5.1 was installed on 16/02/2011 and I started to have problems on the morning of 17/02 which is when I had shut my machine down overnight. I see others have also experienced problems. How do I uninstall it in Safe mode? When I try to I get an error saying "The Windows Installer service could not be accessed. This can occur if the Windows installer is not correctly installed. Contact your support personnel for assistance."
