PC Restarting. Any ideas why?

post #1 of 12
Thread Starter 
Hi,

I recently upgraded my PC. I have installed cooling, and temperatures look ok. It is a good PC with an Intel i975 Extreme and an nVidia GTX 580. I have been playing Dragon Age II, and Mass Effect II for the last couple of months with no problem.

The other day I decided to play the Witcher Enhanced Edition (not Witcher II) and my system rebooted without warning. There was nothing in the Windows System log. It is like the PC shut down, and restarted a moment later.

Weirdly I found that the crash was replicable - I was able to duplicate it at the exact same moment. During the start of the game in Kaer Morhen it crashes at the same point in the cutscene where the sorcerer and the Frightener break through the wall just after you choose whether to fight for the laboratory or to kill the Frightener.

It is really spookily consistent. If I load a saved game at a particular point and then continue to the cutscene. BAM! Crash. Because Witcher (whilst an awesome game) was known for bugs I thought it might be the game.

However, whilst playing Fable III today I had the same problem again, and now I am wondering whether it might be my PC. I tried the demo version of SensorView and caused a crash in Witcher. These are the figures SensorView recorded right before the crash/reboot. Thing is the temperature numbers look quite healthy. I wonder if it is the PSU or some weird bug in both games?

In terms of the PSU 11.40 V is a little bit low but still within tolerances?

GPU*****CPU*****AUX******VCoreA
75 °C****59 °C****52 °C****1.22 V

AUX Fan*****CPU Fan2*****AUX Fan2*****HDD0

Thoughts, anyone?

System specifications
Intel i975 Extreme 3.33MHz
ASUS nVidia GTX 580
6 Gb DDR-3 RAM

No overclocking - everything at factory speeds (although factory speed for ASUS card is fractional over reference card speed).

Which PSU is it you have? Sounds like you don't have a good enough power supply

Welcome to OCN

Please fill in your system specs in the UserCP > Add System screen. We need all the details of your gear to best help out. Also, this puts the gear in your sig and makes it so that people don't have to track down where you wrote out what's in your system, since your system is in every post.

First question: what EXACT psu are you running?

+11.4V on the +12V rail is within tolerances, but also probably indicative of a PSU that's straining to deliver the necessary power. It may well be shutting off to protect itself, causing this problem. However it would be unusual for this effect to always happen at the exact same spot of a game, so it may well be something else.

Are you able to make it through a test like 3dMark11, or Unigine Heaven w/everything maxed out? If it's a PSU problem, it should almost certainly occur on these tests also, as they're far more demanding than The Witcher or 99% of other games.

Have you done a chkdsk on your system lately? Crashing at the exact same spot each time could be indicative of corruption in the game file.

Hmm.

I have filled in my system details. I have discovered that whilst the Witcher crash is replicable, it can be avoided by loading a later savedgame. I am going to run chkdsk, then test the memory, then run Unigine Heaven. In the meantime, any thoughts welcome. I could just buy a new PSU next week.

Thing is, it is allegedly a 1 KW PSU, and I only have one graphics cards, albeit a GTX 580 so the system should only be pulling around half the power it is rated for.

Ok,

Caused another reboot during the Unigine test. Annoying, 'cos that was working ok a few weeks ago. One thing I noticed was that CPU usage was pretty low. CPU heat only in the 40s. However power supply VCore amps were varying quite a lot, from 0.94 to 1.22V.

Running at idle / low load it is stable at 1.22V. PSU? Anyone able to form a view?

I do not know if it is relevant, but my PC and monitor etc. are all plugged into a 6-socket surge protector.

You may only be pulling half it's "rated" wattage but since you don't know which PSU it is, it's most likely of a lower rated tier meaning it's not close to what it's advertised as.

Can you please look and see exactly which power supply you have?

I'm guessing it was a prebuilt before? Do you have where you bought it from or anything about the PSU and RAM brands?

It is an Alienware.

It just says OEM 1KW ATX PSU.

RAM is Elpida DDR 3, 6GB in 3 2GB cards.

My guess would be either a faulty PSU or ram. Run memtest86 for about 10-20 passes and see if it catches any errors.

So given I have a single GTX 580 and no intention of going SLI or CrossFire would an 850W supply be sufficient or do I need a 1KW supply?
