I’ve posted about it before and have basically given up on fixing it at this point. What happens is that I hit the power button, and the fans all spin up to full speed, and the PC does not boot. It just sits there, with fans spinning, forever. It appears that the motherboard doesn’t even make it to POST. Then I have to hard power off the PC and try again. On a good day, it boots on the next try, but on a bad day, it fails to boot four or five times before finally booting. This doesn’t happen every time, but often enough that it’s annoying; probably a solid 50% of the time.
I have replaced the case, PSU, motherboard, CPU, CPU cooler, RAM, videocard, all the case fans, all the cabling, the secondary HDD, the powerstrip, and just now have replaced the SSD hosting the OS. The only part I haven’t replaced is my audio card, but I’ve pulled that out of the PC for weeks at a time and still had the problem happen. I think I also updated the motherboard BIOS, although I can’t remember if that was this motherboard or the last one.
I have not changed any/many of the peripherals. I’ve changed monitors since this all started, and have swapped between two 360 controllers (one wireless and one wired). I have not changed my speakers, mouse, keyboard, mic, or headphones. That could be interesting to try unplugging components until after boot. I wouldn’t have guessed that a peripheral could cause it, but once you’ve eliminated all other possibilities, whatever remains, however unlikely, must be the truth.
The only other theory I have left is that maybe my apartment has really dirty power, and that’s what’s causing it? I don’t have the equipment or the expertise to check that.
