Irq_not_less bsod :(

46 BSODs / 22 days ~ 2 BSODs every day.

You're doing very well so far, compared to your average, but of course this thread will always remain open, so you can update it if need be.

Happy computing!

Test your hard drive too, using this tool: | Seagate

I just noticed your Atheros NIC drivers are old:

Hello again, welcome back!

I'll just explain the dumps, that will give you your conclusion. The latest dump blames hardware outright, but mentions that the nVidia display drivers were somehow related. The middle dump blames hardware again, with a specific bugcheck that means hardware failure. The third dump doesn't blame anything of consequence, but shows that dwm.exe (the Windows graphics effects process) was "on top" at the time of the crash.

As you can see, this is most likely a physical hardware issue, specifically video card. Before going out and purchasing new hardware, though, give the drivers an update:

Code:

nvlddmkm.sys         Fri Jul 09 17:15:58 2010 (4C37918E)

New drivers can be found here: NVIDIA DRIVERS 266.58 WHQL

If that doesn't help, you might as well just run a couple of diagnostics just to make sure. I recommend the Blend and Small FFTs Prime95 tests, and 7 passes of Memtest86 overnight.

I suggest you keep the new drivers for a time, until you determine whether they have solved the problem or not. If do, feel free to play around with different versions; there are many driver releases between July 2010 and March 2011!
