For some reason every so often I boot up my computer, I get a blue screen saying a problem has been detected and Windows has been shut down to prevent damage to my computer with the message at the top saying: DRV_IRQL_Not_Less_Or_Equal. All I know is that this is something to do with hardware. I am running Windows XP. Help would be appreciated.
to this problem will be given the keys to the kingdom - it's one of the most irritating error messages there is, and unfortunately it can be one of the most difficult problems to resolve.
Possible (and common) causes are:-
1. Nvidia graphics cards
2. Network cards
3. USB devices.
It's worth checking to see if you have several devices sharing the same IRQ - in WinXP go to Start/all programs/accessories/system tools/system information then click on the + sign for Hardware resources and click on IRQs
Come back to the thread and tell us what you see - I expect to hear that there are several things sharing the same IRQ - possibly IRQ 20, 21, or 22, depending on what hardware devices you have. It's common to see USB controllers sharing for instance.
I have checked the IRQ's and I have found that my Nvidia video card and my wireless network card both share the IRQ of 3. What I need to know now is how to change the value of the IRQ. Thanks for all the help so far guys
