There was no beeping or anything when I tried to turn on. After I changed the voltage next to power plug on back of computer from 115 to 220, the system actually powered up, but monitors wouldn't come on. I was just trying to see if the whole power system might have failed. Put switch back to 115v, saw green light on power board flashing. After couple iterations of this process system finally powered on at 115v with monitors.
I'll run the suggested programs. Since I need to monitor them for overheating I'll have to do when in office on Tue (its my work computer). I did upgrade to Win 7 from Vista a few weeks ago.
I'll post back results Tue. Thanks much. BTW, got BSOD 2X times since posting message at 2:21pm today.
