Hi,

My computer is rather recent (bought it in september 2013) but lately it's been acting up. So far, here are the symptoms I've seen.

I just stopped playing payday 2 and started watching a streamed video on youtube. About 5 mins later, screen goes black, monitor led goes orange (kinda like in sleep mode), fans start spinning 2-3x faster. I tried pressing everything on my keyboard, moving mouse, mashed ctrl-alt-del, nothing happened. I held the computer's power button to shut it down. 5 secs later, I power it back up, nothing happens and I can't turn it back off with the power button. Had to use the power supply switch. Brought it to the computer store, he called me back after running tests on my computer's components and he said everything worked fine.

So I bring the computer back home, start it up, start playing Payday 2. 10 mins later, same thing happens... screen goes black, monitor led orange, fans spinning 2-3x faster. I turn it off with the power button... I turn my power supply off and wait 2 mins... turn it back on, everything works fine. I then decided to open my computer case to see what was happening if it happens again.

1 day later, come back from work. Turn PC on. Nothing happens... I look inside and ONLY the power supply fan was working and the blue led on my computer case showing that the power is ON. Nothing else seemed to be turned on. So I used the power supply switch to turn it off. Unplugged the computer, waited 2 mins, plugged it back on, turned on the power supply, turned on computer, everything's working.

Would be awesome if someone had an idea of what is going on :/

Thanks,

-Kink

Hi,

Yeah I've downloaded one but I doubt this is a heat problem since today, my computer was turned off the whole day, came back from work and first boot up, only the power supply fan was spinning, power led was lit up, nothing else was working... cpu fan wasn't spinning, video card fan not spinning, computer case fans not spinning, hard drive not spinning, computer wasn't booting at all, only the power supply fan was spinning. So nothing was overheating :p

I'll make my temperature monitoring program log the temperature still just in case.

I've been thinking a lot about this... Especially the last event that happened to me last night. My computer case is opened to try to gather as many hints as possible when my computer stops working. Like I said, last night, I came back from work and booted up my computer which was turned off. It didn't boot. I looked inside the computer case and only saw the power supply fan spinning. Nothing else was working. Which led me to this hypothesis...

Since the power supply is directly connected to the video card, would it be right to assume that if I get this problem again and the video card's fan isn't spinning, it definitely points toward a power supply problem? Because I mean... if the video card was faulty, the computer would still boot up, I'd hear at least the first beep, hard drive would start up, etc right?

Thanks for the help,
