    Specs: i7 4470k, GTX 970, 16GB RAM DDR3, 120 GB SSD, 1TB HDD, PSU Corsair 700w, MOBO Gigabyte GA-Z87X-D3H


    Three weeks ago my computer crashed while I was playing Sniper Elite 4 (I got a BSOD). I didn't care much and just restarted my PC. But then I got several BSODs in the following hours. I googled my problem and TL;DR I used a windows tool called DISM that identified and fixed the problem. BSODs gone.

    One week later my pc suddenly froze, so I had to force a shutdown. When I tried to turn my computer on again it would turn on for 1-2 seconds and then turn off. And it would keep on going like that in an endless cycle. After waiting more than one hour my computer decided to work.

    The next day in the morning my computer turned on normally, but about 1h 30m later it suddenly turned off. I tried turning it on and again... turn on for 1-2 secs... then off... then on... and off...

    So I did just like the last time. Waited 1 hour and tried turning on again. Didn't work. The next day I tried it again... guess what happened... on and off... So I gave up.

    Today, after 3 days, it turned on normally and it's working just fine. There are no weird noises, no lags, but I know it will eventually stop working and then... on and off.

    What could my problem be?

    edit: my drivers are all up-to-date AFAIK

    Also take a close look at the motherboard's capacitors to see if any may be bulging or leaking.

    From what my eyes can see, they seem to be perfectly fine. But then again, it's just what I'm seeing, I don't have any technical expertise. Any other suggestion?

    I don't know if this is relevant, but I forgot to mention in my post that this turning on/off problem started in the same day that I got multiple BSODs. DISM fixed my BSOD problem but the turn on/off problem persisted.

    That GS700 was made around 2012?
    Maybe it is starting to show it's age

    Yeah, this PC was built in October 2013. Every piece of hardware is the original one, except the graphics card which I upgraded about 2 yrs ago. But idk, today my pc worked fine, no crashes so far...

    This is really random but you can try taking out the ram and video card and cleaning the slots with canned air. Check the fans on your video cards heat sink too they might be clogged with dust/debry. If you have some skill I would also suggest checking your cpu's heat sink aswell. your cpu could be over heating it might need to be cleaned and a new apply of thermal compound applied aswell. I recommend Artic silver thermal compound.

    If the pc just shuts off, it probably does not get a crash report. It would be worth while to check out the minidump files anyway

    sounds like it needs a good Air Bath, lint, dog/cat hairs, and fuzzy crap removed. fans will collect lint and fuzz and hairs... very common and does not mean you or wife is poor house cleaner...
    take it apart and clean it....

    Those kind of problems are so hard to troubleshoot. Been through that before. It's awful when those things happen. You just have to start replacing things and hope you get lucky. Anyway start with the most simple things first (like cleaning mentioned above) and work your way up. As mentioned already, power supply would be a good first attempt at replacing components.

    Thx for all the replies, I have an update for you guys: I just got a BSOD called BAD_POOL_HEADER. The funny thing is that my PC turned off 2 times in a row and it decided to randomly turn on the 3rd attempt. I will try cleaning my PC, but it really seems that I have bad HW :(

    If you do winkey R (for run), type in systempropertiesadvanced. HIt the settings button under startup and recovery and configure your crash dump behavior.

    One thing I've found with this sort of thing is the filesystem can get pretty beat up from constant crashes. Once you get it sorted you might want to go for a clean install. At the least do an sfc /scannow

    You got a bugcheck that is attributable to memory corruption "BAD_POOL_HEADER". Maybe a faulty RAM stick,it is suggested to replace the suspect RAM stick, or doing further testing with memtest86 or Windows Memory Diagnostic.

    1. pull the video card and memory except for one strip and reboot, that way your using integrated graphics and minimal memory. if it runs this way how long ?
    2. does the PS stink " it will smell bad if something is wrong with it" it might work for a short time then quit"
