Last week my computer decided to start dying on me - just as I had bought some games from the Steam winter sale... To start off, let me share my setup with you:
ASUS MAXIMUS V FORMULA socket 1155
Intel CPU 1155 i5-3570K
be quiet! Dark Rock 3
Corsair SSD 120GB
Corsair Dominator 16GB DDR3
ASUS Radeon R9 280X 3GB
Corsair 650W PSU
NZXT Phantom 820
Now to the issue/issues I've had/have:
It all started with my computer being unable to startup properly. Basically, it would boot up to the extent that the fans (both graphic card, and otherwise) would start to spin and the computer LEDs would light up for about 1-2 seconds and then the computer would shut down. This would rinse and repeat until you shut it off. I had seen my computer behave this way once previously. The solution then was to switch the PSU off and on again. This time, however, that didn't work. I thought, "alright, maybe there's something wrong with the PSU?" and tried my boyfriend's PSU instead. Still the same problem - boot loop without even getting past the POST beep. After this, I tried all the things you're supposed to: going through the RAM and making sure they weren't the culprits. removing the graphics card, removing SSD/HDDs, removing basically everything without success. This all led us to believe that it was the motherboard. Luckily I had a coworker who was selling his motherboard (MSI Z77A-G43 Gaming mobo, which is compatible with my LGA1155).
I picked it up, switched out all the parts, and booted the computer. My first reaction was, "yaaay, it boots!", but this quickly turned back into dismay as I wasn't getting a POST beep, no signal to my screen either... At this point I was like, "well what the hell is it now, the graphics card?!". We tried some things, like my boyfriend's screen, PSU, switching out memories, etc - still nothing, no signal, no beep. Annoyingly enough, it did work when we took the graphics card out and booted without it. I just assumed that my graphics card was broke, but my boyfriend decided to test it on his own rig back home and low and behold it worked BUT(!) not through the DVI port (which I'm using and he on his rig at my place)... and not on the first display port, but the second port. Now we plan on testing with his screen, with my computer, but meanwhile I'm wondering if anyone has had any similar issue? We're both finding it really weird, the issue/issues don't seem consistent and it feels really sudden.
I also tried breadboarding thinking maybe the chassis was causing the issue 'cause you never know, but nope, still the same issue (MSI motherboard + my graphics card = no signal, no POST beep). I looked through several pages of the forum but couldn't find anything similar to my issue. If I missed something relevant, please let me know and I'll make sure to check that out.
The last thing I remember that changed in my "environment" is that I downloaded and installed new AMD drivers. I doubt this would be the problem though because when I previously experienced the boot loop was before the update.
I'd really appreciate any piece of advise or next-troubleshooting-step!
PS: I saw no physical damage on my motherboard or graphics card for that matter that would suggest electrical burn or such.
