BSOD Driver irql not less or equal

[weniar]

Hello,
My computer had it's power on but the monitor was saying the VGA cable wasn't plugged in. After unplugging the monitor from the computer and plugging it in again, it worked normally. But later the screen just distorted and the computer froze. I started it again manual, but after a short while, the BSOD appear.

The other details as suggested in the guide are?:
Is Windows 7 . . .
- x86 (32-bit) or x64 ? Windows 7 Professional 64 bit
- the original installed OS on the system? as above
- an OEM or full retail version? OEM

- What is the age of system (hardware)? 7 months
- What is the age of OS installation 7 months
Help will be really appreciated. Thank you!

Try updating your Display driver from the Dell Support Downloads webpage for your model. If the latest one still causes problems, roll back to an earlier one. Keep any eye on optional Windows Updates for the driver Win7 wants used.

Was Windows installed with a factory disc? Or was it a disc that was burned? Sometimes the burning process gets messed up and the install will be damaged or not proper. Very unlikely but something to think about if you didn't actually use a factory disc.. The only reason i'm suggesting this is because I had the exact same issue.
