Re-installed my system now Premiere CRASH,CRASH, CRASH

[kenobi]

I am running premiere 5.1c and my RRS. It worked like butter befor my system crashed due to a virus. Now I have re-installed set up my rr presets. 4.31 and 2.1 rr drivers. But everything I do premier freezes and my hard drive light stays stuck on. I can't even Ctrl Alt Delete- sytem is stuck and I have to Power off to get out. Damn. Any help would rock. I need this program to produce, or I'm gunna FREAK!!
