Thank you for all the suggestions, I will have a look.
For anti-virus, I have only run Ad-Aware. I have gone to very few sites with IE (this site, ATI, MSN, and that is about it). I will download the others you suggest and run them. I think I will do this after I just reinstall. The only important thing on the computer is my SFC OP stuff
I will just have to go through the cumbersome windows update process.
Before that I will try the dusting and testing the memory. The inside is pretty dusty.
For DX9.0c, I downloaded from MSN, but I will verify that it was the complete install, not the update.
For temp, what should I be looking for? When I last looked it was at between 98F and 104F for the processor, power supply, and the system.
Once again, thank you for the help.
