This is a very strange dilemma and i hope you guys on Techimo can help out. My graphics card recently started playing up. First it booted in 800x600 which is strange cos i always run it at 1280x1024. Secondly whenever i attempt to change the resolution back the screen goes blank and then goes back to 800x600!

So all that is messing up. So i figured it might be a driver issue so i reinstalled the drivers which hasnt helped a bit. I also reinstalled directx which also hasnt made any difference.
Now this is the wierd part, my previously working virus scanner has started playing up as well. Whenever i try to update AVG it instantly comes up with a reoccuring 'Are you sure you want to cancel the download?' message which can only be closed by Ctrl+Alt+Del.
Has anyone had any problems remotely similar to this? I NEED TO KNOW!
Thanks a bunch
Andy
