I flashed my Bios this week due to a CPU upgrade. I double-checked I had the correct files, all went well. However, now XP Pro will "freeze" after a few minutes and I can only unlock the PC by hitting the Reset button. I can reproduce it every time, although it does not freeze on every occasion, if you know what I mean! For example, opening My Computer and then minimizing the window will freeze the system every time. When I push reset, Scandisk does not even start on reboot. Windows Me, oddly enough, runs fine, no freezes at all. Anyone had a similar experience?
