View Full Version : New 8800 GTS crashing - blue screen 'IRQL_NOT_LESS_OR_EQUAL'

I need help solving an issue that may be due to a new 8800 GTS 512MB which has replaced an 8800 GT 512MB.

Previously my system was stable with an 8800 GT 512MB running stock, not so stable overclocked in some games.

I have had the card for a week and have had about 10 crashes with accompanied by the blue screen IRQL_NOT_LESS_OR_EQUAL message. The first 2 days everything was stable with no issues and now I am crashing about every 2 hours of gaming (Vanguard and LOTRO) running the card at stock.

Another issue that arisen which may be related is that I cannot unpack most compressed files. I became aware of this when I tried to install various NVIDIA beta drivers downloaded from various sites. I cannot open them with Winrar or Winzip as I keep getting a corrupted message. I am even struggling to open self extracting files. There is however no issue with unpacking smaller compressed files.

I have run Orthos Prime for 2 hours and Memtest overnight with no errors.

At first I was thinking that it was the new GTS, but due to the unpacking problems it may be a hard drive issue. AOC is to be released next week and I donít want to miss out so any advice would be appreciated.

Download speedfan and check the SMART status of your drive:

That won't guarantee that the drive is fine, but SMART generally picks up any serious problems a drive might have.

If that checks out fine, try putting in a different video card (preferably your GT if you still have it).

Try uninstalling your video drivers completely, downloading them fresh and then reinstalling them.

The only other thing I can think of that could be an issue is your power supply, but I doubt the GTS uses too much more power than the GT. What kind of PSU you do you?

Other than that... its hard to say. If your system is stable in Orthos (I'd run it longer than 2 hours just to make sure) and memtest but crashes in games its most likely a video card or driver issue. If no drivers fix it, you've either got a problem with a lack of power or a dead card.

I'm not sure about those compressed file issues... all you've done is switched your video card, right?

I have already reinstalled the 169.21 WHQL drivers which are the only drivers that I can install - the more recent beta drivers could not be installed due to the above unpacking issue.

I have previously run a heavily overclocked 8800 GTS 612MB which draws more power than the 512MB card. My 480W Tagan power supply is at least 4 years old so it is possible that it is playing up.

Would the Atitool stress test only stress the Graphics card as that may possibly help with isolating the problem?
