ok, so long story short..... got parts, fought with parts, had heat issues, ended up getting replacment cpu from newegg (first one fried), got fed up and took part to pros and had system built. picked system up last thursday. worked ok, got op system. last night got problem descrbed here (my my outlook grrr thread) well this bites, as soon as I posted and said my new system was working, it quit. it turns on, seems like it's working but no signal to the monitor. then, the power button on the front won't turn it off like normal, it just stays on and I have to kill power to get it to turn off. it was working fine until tonight when I moved it into my room where the computer is supposed to go, and then it worked in there for a couple of hours. it was on and working, I went to set up my old pc on the table outside, I came back and the monitor was off, light blinking like there was no signal. checked the monitor connections, they are ok. 2am... going to bed going to sleep on this and try again tomorrow. building this pc has really been a pain in the ***. now this morning, system turns on and runs for a 10 seconds then turns of. I don't know how hot it's running. I'm really really hoping that I can replace the power supply and fix this. any suggestions? my first step will be to take it back, seeing as how I paid for a setup and it's not working.
