EDIT: It was a bad motherboard.
So my computer seems to have crapped out on me. I figure I may have to replace the guts but I thought I'd start a thread and see if anyone might have any ideas first. If nothing else maybe I'll get an idea of which components to start with. It would be nice if it were something like the battery...
What happened: I usually 'sleep' my computer but went ahead and did a shutdown one night. The next day when I turned it on there was no display or sound. I opened up the PC and reset the video card and maybe the power cable. Still no display or sound, but the computer started resetting about every 10 seconds. I bought a little mobo speaker and it beeps 4 times before the auto-reboot. Per the mobo manufacturer this points to a system timing failure... which seems not to narrow things down as much as I had hoped, though a screwed mobo seems like the leading cause.
I don't get a code on a POST testing card (well I do, but it doesn't get past the FF code for "BOOTING"). A power supply unit tester 'passed' my PSU. Fans run, lights go on but nobody's home. No new hardware recently (not since I last changed out the mobo\cpu\vidcard in 2013). I could upload a video of the boot failure if my description isn't enough.
I have tried: reseating cords, CMOS clear via battery removal, switching my 2 sticks of ram in every possible configuration (have no more DDR3 to completely replace), reseating CPU (no spare CPU except an old one that I don't think is compatible with mobo), unplugging all unnecessary devices, sacrificed a gerbil. I also dismantled and reassembled critical components outside the case thinking it might have been a short. Nothing changes the ugly four beeps.
Specs: Yes, I know it's outdated but I'm cheap\poor it still works for what I need it for.. or it used to work...
Mobo: ASRock H77M LGA 1155 Intel H77 HDMI SATA 6Gb/s USB 3.0 Micro ATX Intel
RAM: G.SKILL Ripjaws Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666)
Vid: PowerColor AX7850 2GBD5-DH Radeon HD 7850 2GB 256-Bit GDDR5 PCI Express 3.0 x16
Intel Core i3-3220 Dual-Core Processor (3MB Cache, 3.3 GHz) Intel HD Graphics 2500
And I can list the hard drives, psu, or whatever else if necessary. No overclocks.
Any ideas? (note: I'll be away from my computer until late Sat).
