Guys I would appreciate any help that you guys can provide Basically, one night there was a blackout and my computer would not turn on again. It would for 2 seconds with fans turning on and it will then auto turn off. I decided to try a new mobo, new cpu, new RAM, new PSU, new HDD (all borrowed) and still nothing. I have stripped it down to just mobo, cpu, video card and hdd. It would occasionally beep once and stay turned on - all fans spinning lights are on, the HDD LED stays on constantly but my monitor will not activate and run anything. I have tried taking out the CMOS battery, trying to reset things but still no progress. Please help, I've tried fixing it for over a week now.. LATEST UPDATE: Ive tested my CPU, PSU, RAM, on yet another mobo ... and it booted up fine .. when i plugged in my HDD, and using it as master and only hdd, it can detect my hdd, but it will get stuck i think on a partition check?, and wont cant load into windows -_- any ideas ?
