When I am playing a game with high system requirements (this time: Battlefield 3) after a while my hard drive randomly shuts off (it's the hard drive. I hear it shutting down.)
After Windows realizes the hardware is gone, it first closes all Explorer windows relating to this device, my current game often also shut down instantly. Then random applications start hanging up and finally Windows crashes due to the now missing system drive.
Sometimes Windows doesn't even show a bluescreen - the computer shuts off and doesn't turn on for a minute after that. This time it actually did show a bluescreen.
Afterwards my computer case was pretty hot, but the temperatures while gaming (second monitor with temperature meter) aren't exceeding 60 °C on the processor and 80°C on the graphics card.
I know my case isn't completely flawless in terms of air flow, but these temperatures shouldn't really be critical, yet, as graphics cards can go up to 120 °C until crashing out.
I already suppose my hard drive temperature is the error, so for a test I put it standing next to the case on a piece of antistatic plastic.
As a side question: What are the maximum temperatures for hard drive?
What could be the source of the problem? I can't pinpoint it.
Alright, new knowledge that could bring me closer to the real culprit.
My dad had a kickass big "Chieftec" case lying around, with lots of air flow and stuff.
So I went and dusted all my equipment with compressed air and put it into the new case. Then I went and played Battlefield 3.
The GPU never reached more than 60° celsius, the CPU never more than 50 ° celsius. The HDD stayed at 25 °c.
Then, after the round of BF3, I browsed a little and... click, the PC went out! Afterwards the PC behaved like a infant trying to walk: It turned on... turned off, turned on... turned off ... ... turned on and off directly... I disconnected the power and while doing that I recognized that my PSU is... really, really, really hot. The fan inside the PSU runs and all, but wow. The rest of my equipment was dandy and cool, but the PSU... Hot.
Which brought me to the culprit of my whole pc being hot all the time. The new case doesn't conduct the warmth from the psu to the whole case anymore.
Another thing because somebody asked about the PSU.
My PSU is a Xilence RedWing PSU with 480 watts and a passive power factor correction. I had this cpu for like 3 years now. Mainboard: ASUS P8P67 RAM: 4x 4gb 1333 Mhz RAM CPU: Intel Core i5 2500k HDD: Western Digital 500 GB (Shown as WD5000AACS-00G8B1) caviar GREEN
Wow, when I think about it... The hint was pretty good, I really think that my PSU might be underpowering the components, maybe this is why my HDD turned off.
HDDLife says that the HDD is still on 91 % "life".
Error Rate is zero, the reallocated sectors are... zero. Spin up time is the thing that is on 91 %. Positioning errors: zero.
I felt couragous and tried playing the game again, until the hard drive turned off again, thus making everything hang up and finally the computer turned off flat again, with that turn-on-turn-off cycle going on. I removed the power, waited a bit, and started the PC again... Then this appeared on the BIOS screen:
"During the last start of the computer a power surge was detected. ASUS Surge Protect was triggered to prevent damages to the system (or something along these lines)".
Wow, it does feel like the PSU is dying.
