    Okay, so here's the deal:

    Whenever the wife's playing Dragon Age or Tropico 4, after about an hour of play the system just dies. Power cuts, off it goes. Doesn't happen when I'm playing stuff through Steam such as Borderlands 2, but these two games are where it seems to happen.

    Any ideas? For a bit I thought it might be the graphics cards (5570 1GB) power draw, but it's a 500w PSU. It just seems to be these two games, though...

    They're good games, too, so little chance of your PC shutting itself off in protest.

    First things to check: memory, overheating.

    Is it a desktop? Open the case to help with the latter. Test the memory with memtest86+ (get it as part of Parted Magic).

    It's probably not the PSU, unless it's faulty.

    Different games stress the system in different ways, so it really isn't a surprise it only occurs in specific ones.

    Wattage isn't the only measure of a PSU's effectiveness - you need to ensure you've got enough amps on the 12V rail to support the graphics card too.

    That said, if you can play Borderlands then you should be fine on that front. Normally if there's not enough power then it will shut down a lot quicker than that, so it's more likely to be an overheating issue somewhere.

    Over heating is the only thing I've ever had to kill a system dead without any blue screen etc.

    Tropico 4 is quite taxing system wise too. Take it apart and give the bits a clean first. It's the simplest fix.

    Install MSI afterburner and Speedfan and see if your system is going bananas.

    Okay guys, going to do these one after the other. Thinking it's likely the GPU overheating, so will give that a clean out.

    Dragon Age and Tropico 3 both used to really cook my GPU. Tropico never crashed but Dragon Age would eventually cause the GPU to derp. Had to turn my settings down. GTA4 was a bitch for it too.

    Dodgy PSU imo.

    Is it rebooting straight away? Have you got your thing set to display blue screens? If it's a BSOD, it might be overheating or simply a driver problem.

    Dodgy PSU was the culprit when I had the same problem

    Might replace the PSU anyway then. Cheers guys!

    Good news is, I know what's wrong. Bad news is, it's the CPU; temperature under 20% load is 50C, when it should be about, what, 20?

    Keep looking. 50c at 20% is fine.

    It's 47-50C constantly, though. When it blacked out a bit ago, when I got back on it was at 57C, and the shut down temp is 65C...

    What CPU is it? If you're getting 50c at 20% load with a AMD proc with the stock hsf I'd suggest you are not doing fine, it it's Intel you are doing fine. Well alrightish anyway.

    Run a quick CPU benchmark like Cinebench 11.5 and monitor the temps and report back.

    Yeah, it's an AM2 5000+ and a cheap stock-looking cooler (has a white plus mark as a logo), so I'd expect far lower under low loads. Think it could be thermal paste issues, but it's better to just replace fan and coolant.

    Get some compressed air in there in the meantime. It can work wonders. :D

    I dimly remember having problems with DA because the frame rate wasn't limited, which put my PC's fans into overdrive after a while. Try to cap the frame rate in the graphics drivers menu,and/or enable vsync.

    So, cold boot from system being off overnight - 40C. It's the thermal paste. till, a 16 repair job later and the system should be good for a few years (which it won't need, as I plan to go for a refresh next time I have 200). VERY glad it wasn't memory...

    Update - PC has been off for 4 days. Took the fan off the CPU cooler assembly, gave it all a clean out, stress tested with a prime number generator - max temp hit 57C. Good times. 1 hour of MWO (which caused a shut down last week) hit max temp of 53C. I consider that fixed for now, then...

    It really didn't need that much time to cool down. You knew that, right? :-)

    Anyway, glad it's sorted. Dust build up can be deadly.

    I had the same. Temps were all fine, after a look at the log and a quick Google, seemed to suggest there was a random audio driver conflict. Reinstalled drivers and it seems to be fine now...

    Starcraft 2 menu melted a good number of graphics cards /o\

    I'd boot it up for a short while, see running Chrome was putting the temp into the 60C range, and switch it off...

    Am having troubles, across almost any game.

    To set the scene:

    Had a few crashes, very rare, on some titles: Guild Wars 2, RUSE, etc. Nothing too often. Crashes required hard reset.

    Got back in to Planetside 2. Had crashes within 40 minutes (usually) of starting play, sometimes as short as 5. Again, full system fuckups.

    Got another stick of RAM, and the crashes vanished. Kaput. No trouble - on any game. When I stuck in the stick, I also cleaned the system - dusty, but not choking any fans or vents etc.

    Returned from hols, and now all games are crashing after random amounts of time - same problem each time: total freeze (mouse sometimes takes a few extra seconds to jam), music/sounds snag/repeat and then disappear.

    No system changes.
    Ran PS2 in a window with coretemp next to it - crashed at 67C, and had reached 74C with apparently no real bother. Seemed totally random vis a vis temp - those aren't high temps, as I understand it. PC is also well ventilated.

    Have run system integrity checks, RAM module checks, etc.

    Specs below:

    AMD A10-5800K - normal speeds
    Asrock FM2A75M-DGS A75 Socket FM2 MB
    8GB RAM
    480W PSU
    Arctic thingy Cooling Fan (big one, not the shitty stock fan)

    As it's an integrated GPU, I figured the CPU temp also shows me, in effect, the GPU temp. I don't think it's heat - perhaps the hot spell has affected the PC more than I thought - but the temp readings seem alright.

    Any other clues? PC works absolutely fine when NOT in intensive 3D games - no crashes outside games.

    Driver conflict maybe?

    How is your pc placed? Has it got plenty of ventilation? If it's stuck in a cabinet thing or up against a wall or desk side then it might not be getting enough airflow.

    The heatwave atm probably won't be helping either.

    If it's affecting ALL games, it could be a problem with the GPU. How old is the system?

    Is 65-75C too much, though?

    I'm gonna give it another clean, and perhaps try to stay off intensive stuff until the heat goes.

    It's under a year old.

    I should add: can run Dolphin emulator with almost no trouble. Had one crash on that, otherwise, no bother - an hour or so, no crashes.

    Who told you 74c is no real bother? Unless things have radically changed in the past year AMD CPUs don't like it past 62c and get unstable at 65c onward. I'd suggest looking at getting the CPU temperature down to something like 50-55c at load. The most obvious place to start is getting some compressed air around the hsf, if that doesn't work replace the the thermal compound and reseat the fan and finally if all else fails replace the hsf with something better.

    Aha!

    Thank you for clarifying - the internet is full of idiots.

    Given that the system was fine when the weather wasn't crazy hot, I suspect the heat wave has something to do with it. I'll lay off until it passes. If the problem persists, then I will probe further.
