Computer restarting when playing (some) games

post #1 of 12
Thread Starter 
I'm having a serious problem with my machine:

When playing some games, the system shuts down and restarts afer a good second or two, without any warrning or indication.
This only happens in some games while others work without any issues.
Everything else (all software besides some games) works like a charm.

I've found (Google) many ppl posting (on diferent forums) similar problems without a single solution
("experts" mostly blame underpowered PSUs)

My machine's specs:
MB Asus P6T Deluxe
CPU Intel Core i7 920
2x 3GB DDR3 RAM
2x DVD NEC 7203
HDD Samsung 640 GB and 1TB
Asus Nvidia GTX285 1GB (replaced in the first week as it was faulty)
PSU LC Power 1050W
2 big (200+ mm) and 4 small fans running in the case
Win XP SP3

I have custom heatsink and fan for CPU (Prolimatech Megahalems)
and GPU (Arctic Cooling Accelero Xtreme)

Like I've said it only happens in some games (Mass Effect, Splinter Cell, NFS Shift...)
while others run without a problem (Dragon Age, Madden 08...)

It can happen after 1 min or 1 hour.

Never had any problems runnig many applications at once (for ex. Firefox (with 10+ tabs open),
uTorrent, Photoshop, Illustrator, Corel, Acrobat and VLC with video playing)

Comp was in service, they changed RAM just to be sure and tested PSU and it was fine.

Temps are fine during gaming, about 40-45 on the GPU (I usually have display on 1600x1024 or 1900x1200),
between 40 and 50 on CPU. I've tested CPU with Intel Burn Test with no problems.
Tested GPU with Furmark, no stability issues, peak temp was 60, was 59 for the most part,
cooler was running on max - I never hear it as loud as this was when running games.

Any ideas?
Help me please.

Yes I would totally agree with the power supply. Its hard to determine what's your problem. Might be unstable system, might be overheating and you said there is nothing wrong with any of that but I 100% recommend you getting a good power supply. For me its like the heart of everything. Having a decent power supply will keep your system very safe and also good for overclocking in the future. You don't need a 1000w power supply. You can always get a true rated 750w power supply.

Here I made things easier for you.

I hope it helps.

But wouldn't this happen in all games (if it was PSU problem) rather than just some?

Like I've said I've had the machine in service and they tested PSU and said it was fine.

Also, I don't have a spare or can afford a new one.

If I would be able to, which of those from the link below would be recommendable?

Unfortunately not. I've seen this issue recently in person and it's a fascinating one as the only games that exhibited the issue were DiRT2 and Dawn of War 2. Metro 2033, Civ5 and other hard-hitting games were fine. There doesn't seem to be rhyme or reason to what games have problems or not.

Now, it might not be your issue, but it's another possibility on a long list. Does the Windows Event Log detail what crashed? Tried different drivers?

Driver for what? Graphic card? I've updated them about every 3 months since I've had this machine, and it has been happening with all versions.

Event logger - sometimes there are some X's, sometimes there's nothing
(for ex. time of last event than a few minutes later events of the system booting up)

So best thing would be to try and borrow some PSU somewhere and see if this happens with a different one as well?

And update:

I've switched the 2 cables for graphic card to two different outlets on PSU (there are 4).

Also, a suggestion from a friend, I've pulled out one of the 3 RAM modules.

No more crashes in one of the games I've had problems with for almost 2 days now. Will try other games as well and post results.

Same thing happend on my older rig and it turned out to be a faulty psu, Sometimes crash after an hour or 20 sec. Do you have another psu you could borrow? switching cables probably will not help atall as they run on the same rail

Well, a good week after plugging GPU into two different PSU outlets,
the restart still happens now and then, but a lot less than before (once every couple of days versus every half/full hour)

Restarts seem to happen more when my comp is running for a while.
I get hours of uninterrupted gameplay when turning on a 'cold' comp.

And no, I don't have a replacement PSU (or can afford one right now).
I've also figured out that the majority of noise is coming from the PSU fan
and PSU vibrations transferring to the case...

Time to grab a good PSU. Check out PC Power and Cooling for recertified units. I've been using their 750watt unit for 5 years with zero issues.
