Ok.. My first post on these forums =D In the last couple of days I have been doing some video editing with Corel VideoStudio Pro X2. Today when I was doing some editting, I noticed 2 of the files in the video were not co-operating with the video editor, so I deleted the files from the HD (This was hard as Explorer crashed a few times before I could delete them) I then restarted my PC after increasing virtual memory to MAX to find out that almost every video file crashes when I try to do something with it. It (The program I try to play/edit it in) crashes when I try to play it, try to edit it in video editor or try to edit it in explorer. So now I cannot play almost any video. (I havent tried all of my videos yet, but the ones I have don't work) ANy idea whats wrong? Ive tried everything from re-installing the video editor to re- downloading the videos. This means its an XP problem, ye? Just to let you know, im no noob with computers. Ill give you some of my pc specs: 2gb DDR2 533 RAM 1.6Ghz Dual-Core Celeron (775) MSi p4m900m3 MB 256MB HD2400 Pro GFX Card 160Gb Maxtor HD

"(This was hard as Explorer crashed a few times before I could delete them)" That does not sound good. I suggest you run Chkdsk /r to check out your hard drive. Running 'memtest' for a few hours would also be a good idea. "after increasing virtual memory to MAX" I'm not sure what that means, but I suggest that you change it to 'System Managed size'. After that I would do some malware scans.

I just did a chkdsk, all ok. memtest reported errors at 1%. With no programs (except AVG) running. Its not overclocked at all either. Its under warranty still, but I am not 100% sure it is the RAM, it might be my board.

I don't know what memory test you are running, but I suggest memtest86. It runs under DOS. http://memtest86.com/ Memory errors are not likely to be caused by a motherboard problem. But either way, it should be covered by your warranty.

I ran memtest86 from cd last night. It got to 100% with no errors. What does that mean?
