Have you tried to contact Dell to query the updated BIOS message?

Hello Kamranashraf2,

I am from Dell Social Media and Community.

Blue screen errors may occur for both software and hardware issues.

First you can follow the link below to run a basic hardware test, if you get any error you can associate it to in the list

provided in the link.

Pre-Boot System Assessment (PSA) Diagnostics and Error Codes For Dell Computers | Dell

If the tests pass, follow the link below to repair your operating system.

Let me know if you need any further assistance. I will be glad to help you.

Windows 7 Ultimate x86

For anyone who is getting similar problems by installing Win 7 on this laptop (Dell Inspiron N4050). I've made this, and it solved all my problems:
- Change AHCI to ATA mode on F2 Bios Setup.
- Format then install Windows 7 (i used Ultimate x64 SP1). When the setup is finished, do not restart.
- Downlad the Bios update and install it (Drivers & Downloads | Dell US)
- When the bios setup is complete, reset and then install all necesary drivers.

Additional: I only downloaded and installed the WIFI/Bluetooth driver (the 311mb one) and then update the others drivers from Windows Update.
