I just bought myself a new PC and there is some problems. It seems that when my hard-drive go over some amount of rpm, I get interference on my screen. It almost looks the same as when you get a cell phone call and your phone is near the screen. I have moved my pc around, pluged in another screen and check every piece of hardware in the case. No use. Please Help!!!
This is nearly always a power supply problem. Depending upon the cost/age of the case, either the PS is too small for the load or the electrolytic capacitors are dried out due to heat (this causes the voltage to drop and ripple to increase, leading to interaction with the video). The second scenario is usually due to the PS fan seizing up over time. In your situation, it's probably the power supply pooping out due to marginal specs.
