I just built my first computer (just over a week ago). For the most part it runs like a dream, but every so often it crashes on me without any explanation. No BSOD, no error messages, just all of a sudden I get a black screen - more specifically, I lost any kind of signal to my monitor. Fans and LEDs are still on and running - if anything, the fans louder. First guess was of course a bad monitor, but that's not the case- I've had other things going (music, Skype, etc) which also stop working when this happens. It's happened at least four times since I built it, all after having been running for different amounts of time: the first time maybe an hour, the second (directly after the first) 45 minutes or so, the next several days later (each day I was using it for at least two to three hours at a time) after being used all day, and the most recent after only half an hour or so. Best guess is that something is overheating, but I don't know what, and it could be something else. At least two of the four times it crashed while I was running Photoshop; I don't remember what I was doing the other times.
Once (I believe the second time it crashed) the monitor did something different: I got vertical green bars for about 3 seconds before it finally went down, and the music that I had playing (mp3s in iTunes) started skipping. The other times it's just gone to a sudden black screen. I'm dual-booting Windows XP x86 and Vista x64, and it has happened in both (plus once in the brief time I was running XP x64). Here are the hardware specs, all purchased on NewEgg and all having high ratings.

My processor didn't come with a heatsink, so I bought one off the shelf at Best Buy - it's Rocketfish brand.
Any help on this would be grand. Thanks friends.
