Hi people. Bear with me here I wil give as much background as possible. Here's my problem !! I have an advent PC which is about 4 years old but was pretty high spec when u got it. Ove rthe last couple of months i have had some issues with the hard drive being unable to be read. Prior to this at times my system would just open lots and lots of blank IE 7 tabs. I have also recently installed a mmg from games campus and thought that might cause a problem. I have had it installed on my laptop for over a year with no issues. Having now had a new hd installed ny an engineer. I have had exactly the same issue again. Although this time in the run up to the meltdown my pc kept telling me it had to increase my virtual memory. Today i have again restored to factory settings and all is fine running avg, IE7, mozilla etc. I have tried to run memtest86+ with a free dl burnt with nero to cd. But when i reboot it starts the exercise but then stops with the [DS-DOS]A:\> as if waiting for a command. Ultimately the question im asking is ; Could it be a ram problem that is causing the aggravation in the first place ? Am I doing something worng with the memtest dl ? Thanks and sorry for the long windedness of my post.....If you are still awake any help would be appreciated. Andy.
