Windows 7: random BSOD, error 0x0000003B

Hi all, first post here.
Let me say i'm impressed with the organization level around here. You all are doing a great job here.
Now, to my problem: i'm having a seemingly random BSOD. It oftenly happens when i leave the notebook overnight downloading, but also happens when i'm using it.
Sometimes it also happens when i open the lid of the notebook after keeping it closed for a while.
I'm having more or less 3 or 4 BSOD per day.

Hello chatoalbert and thank you for your kind words.

BSOD Analyse

How long have you been running Windows 7 on this motherboard? I believe that your hardware barely can support running Windows 7. Your BIOS is from 2009 which could be problematic.

Here are some of my suggestions:

• Search your hardware parts on the Windows 7 Compatibility Center, and ensure that Microsoft has approved the product to be 7 ready.
  • (For an automatic check, you can use the Upgrade Advisor)

• Windows 7 Upgrade Advisor - Download - Microsoft Windows

I've been running for almost a year and half, without any major hassles. And it gets better: this notebook came with a Windows 7 Home Basic license XD. Anyway, I'll download the Advisor and let you know about the results. Thanks again.

Also, i've made a memtest during the night without any errors, as well as a sfc /scannow - also without errors. As soon as I get home i will proceed to run a chkdsk and a malware check with malware bytes, just to be sure.

Alright.
Thanks for the update.

Best Regards,
Frederik.
