BSOD error code help

I've had crashs and BSOD recently (BSOD a few times, once playing Guild Wars, once while watching a video on VLC) and once it restarted by itself, no BSOD.

checked event viewer, found the error code for the last time it BSOD'd on me, and it said

Error code 100000d1, parameter1 00000004, parameter2 00000002, parameter3 00000000, parameter4 ba61304b.

I googled the error code and as far as i know, its most likely a driver or ram problem, I'm unsure on how to check what's wrong and fixed it, so can anyone help me on this?

thanks.

Have you updated drivers lately if so try reverting back to the old ones that you updated from if not then try updating your drivers thats one of the most common problems.

if there's a problem with your ram, you can try borrowing ram from a friend (assuming they will fit into the same dimms).

BSODs are usually either a sign of failing hardware or bad drivers. Ensure the drivers for all your hardware are up to date. To test the stability of your ram and processor you can use a program called Prime95 (use google to dl). The second post here http://www.tomshardware.com/forum/24...ablity-prime95 explains what settings to use to test stability. To stress test your graphics hardware run loops of 3dmark. To exclusively test your RAM google memtest86.

I hope you had not updated your video or sound driver. If you have, uninstall it then install the previous version. I would also report the errors to the manufacture.
As for stress testing the hardware, If you have not changed any drivers that would be the next step.

Just to give you the standard blurb about d1 errors (which you probably already know)

DRIVER_IRQL_NOT_LESS_OR_EQUAL (d1)
An attempt was made to access a pageable (or completely invalid) address at an interrupt request level (IRQL) that is too high. This is usually caused by drivers using improper addresses.
