The Problem: Sometimes during normal operation my system starts stuttering, the whole system. So say I'm listening to some music and running an application. My mouse, application, and music will all start stuttering. I restart my computer and sometimes it won't boot. I will get a blank screen as if no signal is being sent to the monitor. The OS is installed on a RAID 0 (Two SP2004C 200GB). The array comes up healthy every time on boot. Besides the stutter the system runs fine.
Things I've Tried: I swapped out the RAM and the same problem happens with the other RAM. I have defragmented my hard drives as well. I have scanned for spyware with Spybot and AD Aware SE Personal. I've scanned for viruses with AVG. I had my processor set to 215Mhz from 200Mhz Core Clock in the BIOS. I'm thinking maybe I damaged the processor so I set it back to 200Mhz. But, the first power supply that came with this system was faulty. This one is better but maybe it's still not enough, I don't know. It's a 400Watt Power Supply. It could also be the processor or motherboard too I suppose. I don't think it's the hard drives because the booting with a blank screen is before the hard drives. This makes me think it's the processor or power supply.
Any ideas on what is causing the problem? I was thinking of getting a new processor but I thought I'd ask some second opinions before I do. Does this sound like a power supply or processor problem?
