Hey ive got the same problem, (that my computer gets to the irql not less or equal blue screen)
cept my situation is a little different...
it only happens when i try to start in safe mode but its not just occasionally.. its everytime, ive never been able to boot up in safe mode. i also thought it was my ram except ive taken out a stick at a time since i have two... and i try booting up wiht one. and with both sticks, it still got to that blue screen.
i was trying to boot up in safe mode to delete something by pushing F8 cept i kept getting to that blue screen so i tried setting the computer to boot up in safe mode from msconfig not realizing i wouldnt be able to change it back after shutting down the computer...
so my real problem is that i need to restore the msconfig file back to the original one. i found the command for system restore from command prompt except i cant figure out how to get to the command prompt.
what ive done so far is.. my friend has used the recovery console and did "fixbootmbr" and then after doing that.. it said ntldr is missing which really pissed me off cuz he said he knew what to do.. but i got the ntldr file back and im back to where i started.. now i just need to get the msconfig file back. or something...
ne ideas would be sooooooo appreciated
i do remember running chkdsk except i dont recall what it said ill do that again and repost it.
