I'm not sure if this is the right forum for my problems since on the face of it despite the scans and tests I've run nothing is showing up as wrong.
Broadly every so often my PC just locks up completely the only solution to which is to push the reset button. However, I'm beginning to think that it only locks up when I am using the internet.
I am running Windows XP without service pack 3 installed. My PC has an AMD Athlon 64 processor 3700+ with 1GB Ram, 2x 150GB internal hard drives, 1x 300gb external usb hard drive and 1x 1tb external usb hard drive. Video Card is Nvidia GeForce 6200SE TurboCache.
I am running Kaspersky Internet Security 2009 and Win Patrol. Since this problem started I have also installed Spyware Blaster and Ad-Aware Free with Ad-Watch Live! turned on.
I have done a full scan with Kaspersky, Spybot S&D, Ad-Aware and Trend Micro's online scanner. None showed anything of real note, just a few cookies along the line somwhere. During all of these scans everything worked perfectly. However, the problem first arose when checking some web mail online and does seem to occur only when I am doing something online with more than one tab open in the browser. The lockups have occured while using Firefox, Opera, Flock and IE; all latest versions with the exception of IE which is version 7.0.
Have scanned hardware with PC Doctor 5 without which showed all OK.
As a last desperate attempt at solving this problem I have blown out the inside, which was full of dust, with an air aerosol and re-seated the memory sticks. Following this I re-ran PC Doctor. Have tried running the PC with the side of the box removed in case it was overheating but this seems to have made little difference.
I am typing ths on my wife's laptop in case my own PC goes belly up in the middle of this long post.
I hope that someone out there may have some idea of where to go next............ probably for a new PC I guess!
Anyway, thanks for listening.
Just been using Microsoft Expression Web for about 45 minutes on the machine mentioned above, while previewing a web page in Firefox computer locked up. However, this was not the first time I'd used the preview feature during this web site building session.
