I get these blasted annoying random freezes. Everything that's already running works in terms of audio, but becomes nonresponsive when I get them. If I'm talking to someone on Skype, I can continue to do so but the applicaiton is frozen and so is the rest of my computer. I can try to launch new stuff, but it won't launch until after the freeze is over. This goes for doing just about anything else as well.
I get no error messages ever whatsoever.
I got this only after buying a new GPU, however, a Nvidia GT 240. I only bought it to replace my Sapphire 3870 HD when I got these odd complete lock-up freezes when watching videos on things like Windows Media Player Classic HC. (I still have the old card just in case stowed away somewhere.) When reisntalling the drivers, I used Driver Sweeper to remove my old ATI drivers and install the Nvidia ones. Everything is fine but I still have a display driver/folder that simply wont be sweeped. Thought it was worth mentioning this.
I'm running XP SP3, Raid Mirror for my 2 HD's, AMD Phenom 9600 Quad Core Process (Black Edition), 2 GB RAM, and a Asus M3N78 PRO Motherboard, and my Nvidia GT 240 GPU.
So far I've tried Defragging and Fixing/Cleaning my Registery (I have full Backups) - seemed to make the issue occur less often, until recently, so then I tried clean-installing up-do-date Graphics Drivers since the freezes have been coming up too often. This seems to make it even more rare now, but they last a lot longer. I also checked if it's a heat problem. It doesn't seem to be, unless my Processor shouldn't be idling (at most running Chrome) at 45~50C.
In conclusion, Help please.
