Hi all Basically the question is in the title. I have a Inspiron 5150 and she was working fine with xp pro on it but decided I would try 7. The install went along swimmingly but at first boot after the windows splash screen I got a BSOD. The error is driver_IRQL_not_less_or_equal. Start up repair It boots up fine in safe mode and checking the device manager I found that there were a few driver problems. So I went to the Dell site and got the few I needed and then found that according to Dell the 5150 does not support Windows 7, yet several searches over the last week has told me allot of people are running 7 on the same notebook. I installed all the drivers it would let me (some came up with an error saying "only for XP") and now the only two that are flagged are Network Controller and PCI Modem. I do not have the original drivers disk that came with it. The service tag number is GL6KB1S If anyone has any answers or things I may need to try I'd be more than happy to hear them.
