I built a rig just over a year ago, it's an Asrock Z77 Exterme 4, i5-3570K, Gskill Ripjaws DDR3 4 x 8 gig, Samsung 840 Pro SSD, Rosewill Green Series 630W PSU, no videocard, just used onboard graphics.It's always run great but yesterday it was running, and I walked away for a few minutes, and when i came back, it was powered off.
I restarted, the fans turn on, ther's no beep, no post, nothing on the screen. I get a dr debug error code of A2, which is IDE detect.
I checked all connections, no post. Tried unplugging all SATA devices, except boot drive and swapped 1 or 2 sticks of ram in every memory slot combination, but still no post. Cleared the CMOS, still no post.
Checked my HD in my other system, and was able to access it, so I think the HD is ok.
I'm guessing it's either the mobo or the power supply. I guess I can try installing my power supply in my other system and see if it starts up.
I don't know why either would fail in just a year.
Any other suggestions?
