Hi, just recently with any sort of game I play the comp decides to shutdown instantly. This happens randomly whether it will be the first 10 min of gameplay or 2 hours. Is this problem due to heating? Or graphics card issue/ power supply?

This only happens playing games and not at the desktop, downloading, burning etc.

My comp is running Quad core with windows 7 64 bit, 4gb ram, 550 watt power supply, geforce 9800gtx card (its old now) etc.

Any suggestions would be helpful.

i had a similar issue with my laptop where during anything with a high memory usage (such as playing games) it would shut down. it was an overheating issue due to the heatsink being full of dust and fluff so airflow was dramatically reduced. when playing games, etc the fan was always roaring. even just using photoshop made the fan roar. cleaned out the heatsink and it's all quiet again and haven't had any issues with overheating or switching off. also when i got this current computer off my brother the fan was loud to start with so i cleaned the heatsink as it was moderately dirty. made it run a bit quieter.

whether that is the same problem as you are having i don't know, but it would be worth opening the box up and just seeing if the heatsink is clean and the fan is able to get enough airflow through it to keep it cool

How long has it been since it was given a proper clean/dust etc?

What games does it fail on?

What screen resolution?

As for the rest, as Jacob said, have a crack @ those two and let us know.

By the sound of it i'd be surprised if Furmark doesnt make it fail in mins :)

Although you'll need to rename furmark.exe as the Nvidia drivers look for it and fudge the GPU via the drivers IIRC.

All solved, my comp is dust free and there was shit loads of it. I'm assuming the dust was trapping the heat in and hence why I had those random shutdowns. Thanks for everyone putting in useful suggestions.

i think the ur pc is trying to hint u should go out and see some light...come back to civilization

Like you can talk when you actually made the effort to post petty crap like that.

    • Bit of a pity we don't have good images of the back/front of the PCB ~ that said, I found a YT vid of a teardown to replace dicky clock switches, and got enough of a glimpse to realize this PCB is the front-end to a connected to what I'll call PCBA, and as such this is all digital on this PCB..ergo, battery voltage probably doesn't make an appearance here ; that is, I'd expect them to do something on PCBA wrt power conditioning for the adjustment/display/switch PCB.... ....given what's transpired..ie; some permutation of 12vdc on a 5vdc with or without correct polarity...would explain why the zener said "no" and exploded. The transistor Q5 (M33) is likely to be a digital switching transistor...that is, package has builtin bias resistors to ensure it saturates as soon as base threshold voltage is reached (minimal rise/fall time)....and wrt the question 'what else could've fried?' ....well, I know there's an MCU on this board (display, I/O at a guess), and you hope they isolated it from this scenario...I got my crayons out, it looks a bit like this...   ...not a lot to see, or rather, everything you'd like to see disappears down a via to the other side...base drive for the transistor comes from somewhere else, what this transistor is switching is somewhere else...but the zener circuit is exclusive to all this ~ it's providing a set voltage (current limited by the 1K3 resistor R19)...and disappears somewhere else down the via I marked V out ; if the errant voltage 'jumped' the diode in the millisecond before it exploded, whatever that V out via feeds may have seen a spike... ....I'll just imagine that Q5 was switched off at the time, thus no damage should've been done....but whatever that zener feeds has to be checked... HTH
    • I think Fitmit had some, have a look on there (theyre Australian as well)
    • Hah, fair enough! But if you learn with this one you can drive any other OEM manual. No modern luxury features like auto rev-matching or hillstart assist to give you a false sense of confidence. And a heavy car with not that much torque so it stalls easily. 
    • Actually, I'd say all three are the automatic option. Just the different trim levels. The manual would be RSFS, no?
