That link you found is correct Louis. My computer has an Intel Pentium D processor so I did not not think SP3 would be a problem.
I live in Scotland by the way.
I cannot remember exactly what happened when I tried to use the recovery discs it was about three weeks ago. It loaded the first screen and I chose R to start the recovery process then it appeared to start scanning through files there was one of these dotted white bars scrolling along the bottom of the screen and various file names being shown. It did this for about a minute and then I got a blue screen saying that the BIOS were corrupt. I'm afraid I didn't take a note of what the error message actually said. That was when I decided that I would just let the proffesionals deal with it.
I imagined that restoring the computer to its factory settings would have resolved any problems. Is this not always the case? If it has a virus will it still be there?
I managed to get it to load windows this morning and thought I would scan with some of this sites recommended antivirus/spyware.
Downloaded Spybot Search and Destroy which found a couple of tracking cookies but nothing serious then tried Panda Antivirus scan but it only managed to check 12% before computer rebooted again
It did say that there were 4 infected files though but what they are I don't know.
I did install more ram but it was a few years ago not long after I had bought the computer. Surely this could not be causing the problem now?
