Random BSOD

Please update your BIOS, you have version A12 but A13 is available.

Code:

BIOS Version:              Alienware A12, 8/20/2012

Very odd, I see an update.

How so?

I have an M17xR3, the BIOS options you found are for an M17XR4

I searched for M17xRx, that is what is in your specs.
But I see it yes, no BIOS updates available.

Please reinstall every driver from Dell, this replaced any corrupted driver, possibly updates some and may help something.
After that, try to run driver verifier.

Diagnostic Test

 DRIVER VERIFIER

   Warning

Please make a backup of your important files and get your rescue media or create one.
Please create a restore point.

Please follow this tutorial to run driver verifier.

Driver verifier stresses your drivers and will crash your pc if any driver fails due to a violation.

Driver verifier should be performed for a max of 48 hours, or when you have a bluescreen, whatever comes first.

If driver verifier has found a violation and you can't get back into windows normally, try to boot into safe mode and reset in safe mode driver verifier, or in the troubleshooting options open command prompt and type verifier /reset.

   Note

Your system will act very sluggishly while driver verifier is enabled, this is normal as your drivers will be being subjected to heavy testing in order to make them crash.

Looking at the usual causes of the most common crash, the 0x101(CLOCK_WATCHDOG_TIMEOUT), which are

• Device driver,
• BIOS bug,
• hardware defect

if drivers reinstalling/updating doesn't help and driver verifier doesn't flag anything we are probably looking at a hardware issue.

With the 0x101 it would be the challenge to find software causes.
