A customer phoned up earlier today with a strange problem. He just purchased a Gainward ti4400 to use with his Epox mobo, XP2000 and Windows XP. But whenever he tried to play a 3D game the computer crashes with a blue screen error which "says something about an IRQL". It's had XP reinstalled, and had 3 new motherboards - previously had an Abit and an MSI with same problem. Anyone got any ideas before I go round there tomorrow? EDIT: He has already had 2 people round to look at it, and both gave up and left! I want to be the one that fixes it really.
Do what BradfordPimp said , ive had similar problems recently , moved sound card to another pci slot (all fixed) For some reason i had 4 devices sharing the same IRQ line , moved the card and all devices now have there own IRQ line and no more crashes/freezes/blue screens of death.
i would guess its the card, try it in another system, if ithe same happens, RMA it for him. Check CPU temps, RAM, all the usual stuff. .icecube
modem / sound card /network card etc all on pci not the graphics card. The pci slots and the agp slot can be allocated the same IRQ . This can cause a conflict. By moving the cards that are in the pci slots this can ensure that the devices are not using the same IRQ line as the AGP slot.
yea, didnt read whole thread. btw, proberly isnt the problem, as Adams told me it only happens when the person is playing games. i think its a fault in the build of the card, maybe overheating GPU? .icecube
i actually edited it before you posted, because when it went back to the thread, i re-read it. my bad... .icecube
Its a very similar prob to what i had , it only happened when playing games or 3d mark etc . Changing the pci cards around solved it for me. It was getting to the point where i was about to throw the bloody thing out of the window - but im all happy now .
Hope it is the problem cos at least its an easy fix , but if not a bit more head scratching required !!!!
I'm going to try swapping out his RAM, and rearranging the cards - thanks for your input bradfordpimp. Any other suggestions very welcome.
A friend had the same problem with his GF2 Ti, turned out to be the PSU. He had a cheap 300w thing installed so he upgraded it and it worked fine ever since.
Just noticed that in my profile it says adamjsmith.com it should be .co.uk - what is on there is equally funny but unfortunately not my work.
it's possable i had the same problem, when i upgraded from my old gf2 ultra to gf4 ti4600, it would give me BSOD'd with "irq is equal to or less then" simply install the latest 4 in 1's (4.38s) and install 29.xx drivers... that is if thats the problem.
An "IRQ is equal to or less than" is a driver issue. Somewhere on www.microsoft.com there is a little guide to decyphering blue screens. Might be worth taking a look at.
Hmph - installing the latest 4 in 1's and detonators didn't help me! I'm still getting IRQL_LESS_THAN _EQUAL and PFN_LIST_CORRUPT BSOD's. Does moving PCI cards actually work? this and black magic are the only things I havent tried yet....
