I am above average for IT knowledge. I had and ran the beta and RC just fine. I installed win 7 prof 64 bit when it released and had no issues until the critical update on 12/3, after that I get reboots and blue screen crashes every 20 min or so, depending how many resources I am using. I swap to my RC and everything runs fine for days. I tried a restore and I got corruption of everything, I spent a great amount fo time reversing that, I have tried multiple times, no way restore will work and this install is not working. Its not hardware or my rc would not work, it has to be something else, but I have no idea what to do from here. Please advise if I am the only one or if there might be a resoltuion, or even if this is a known issue. Also, how long is the rs good for, currently its the only install working, and I would hate to lose it before getting this issue resolved.
