This is my first post so I will try to explain as well as possible, but I'm sure I will forget some things. I had built a PC in January of this year, mostly for gaming purposes. It worked fine for about 3 months with no issues whatsoever. About the end of March, whenever I would play any sort of GPU/CPU demanding game, I would get a sort of buzzing sound loop and a total PC freeze that could only be resolved with a hard shut down and reboot. This occurred pretty regularly and at anywhere from 10 mins to an hour into playing. This would also cause difficulty restarting the machine as I would normally have to attempt to power it on multiple times after a crash before I could actually get a signal to the monitor and a normal boot. This was also coupled with a DRAM led lit on my motherboard during the times when it would NOT boot correctly.
I started to dig into the issue and tried multiple things to no avail: memtest86+ turned up no issues, hard drive scan gave no errors, hardware monitors showed temps were fine, tried different combinations of RAM seating and testing, turned on XMP in bios, updated BIOS, updated grpahics drivers, maybe more but these are the things I remember.
Kind of limited in the amount of time I had to mess around with the thing, this ended up going on for a couple months. Eventually I came across a suggestion to check my PCI-e configuration on my mobo. Turns out, I had my GPU in a slot that was being reduced to 1x speed (4x slot that got dropped to 1x because of another card I had in the first slot, some kind of weird MSI board thing). I reseated my GPU into the top PCI-e slot that is supposed to run at 16x and my problems vanished. From most things I read, this shouldn't have really been the problem or caused crashing, but i figured maybe this board gave different voltages through different PCI-e slots and who cares anyway, it's working.
It did work absolutely perfectly for about another 3 months and now last night the problem has suddenly returned, albeit with slightly different symptoms. Now when it crashes, it instantly attempts to reboot itself and if it is successful I get a message that "Over clocking has failed" and options to enter setup, load default values, or restore to last known working settings, none of which fixed the issue. Otherwise it is the same issue that occurs in about the same time frame of running a game and has the same issues booting up on occasion with a lit DRAM led when it cannot boot.
A lot of things I have read suggest it may be a PSU issue or RAM esp. with the led that is on, but I hate to just start buying stuff without some input. Aside from obviously looking for a solution, I'm trying to learn a little bit about what is happening here or if anyone has seen something similar. Is there anything I can rule out at this point? Can I be confident it is a hardware issue? Did reseating the GPU actually DO anything or was it a happy coincidence? Why/how could this happen in intervals where there is no crashes and then constant crashing?
Any help would be greatly appreciated and I can try to perform whatever testing would help arrive at some kind of solution if needed.
