"To answer your power surge issue - get a good quality UPS (Uninterruptible Power Supply).
Here's what a UPS will do for you:
Absorb relativel small power surges.Smooth out noisy power sources.Continue to provide power to equipment during line sags.Provide power for some time after a blackout has occurred
Just wondering if you have updated Windows and all your hardware drivers?"
"I agree that the issue may be RAM-related, since the system uses some memory-intensive applications, and it freezes intermittently.
Have you run a memory test on your system? If not, please type mdsched.exe in the Search box on the Taskbar at the bottom of your screen and hit Enter. Windows will test the health of your RAM after a reboot."
