Ok, so I have tried various things, and nothing has worked. I have replaced the CPU, the PSU, and the Motherboard, and still, nothing has worked. What else is there to try? I tried resetting the BIOS, but unless the battery is in wrong, that didnt fix it. What else is there to try? I'll state my problem again. I try to power on, and everything inside the computer starts up, I dont get a post up beep and no feed to the monitor. When it crashed, I was burning a CD, and everything just turned off as if it was a power surge. It worked again after that, after giving me messages about CPU Overclocking. I tried burning the CD again, and it crashed again, and didnt come back up. So, is there anything else I can try?
