Windows 7: New fairly regular BS0D mostly when "idle", once whilst on youtube.

New fairly regular BS0D mostly when "idle", once whilst on youtube.

I've been getting a few BSODs recently.
Mostly when away from the computer, but once whilst browsing.
I have not changed any hardware.
I have moved the computer from one room to another and changed the ethernet cable connected.
I do not believe any damage could of been caused to the hardware when moving but I suppose it is a possibility. It took no noticeable bumps or shunts.

I have recently activated ssh with cygwin, which created a new privileged user. But I do not see how that should affect it.

I have also changed a setting in utorrent "Enable UPnP port mapping" and "Enable NAT-PMP port mapping" have both been activated. Again I don't see how this should cause BSOD but I'm trying to provide as much info as may be relevant.

I've attached the seven forums diag tool directory.

Thanks in advance for any help!

Not that I can weigh in on much here, but I can say that it's very unlikely that your uTorrent settings caused this; I use the same settings with no adverse effects :)

Cheers! Just wanted to include as much info as possible about anything that has changed.

I just want to also add that I've now set my dumps to capture kernel dumps in future in case this helps more. I'll upload if I've anymore.

You can upload it in mediafire, and post the link here.

► First of all, I will suggest a BIOS update.
BIOS Version/Date    American Megatrends Inc. 0507, 10/12/2008
► You need additional storage.
Drive    C:
Size    232.88 GB (250,058,108,928 bytes)
Free Space    39.77 GB (42,706,132,992 bytes)
Drive    D:
Size    931.51 GB (1,000,202,240,000 bytes)
Free Space    33.46 GB (35,928,895,488 bytes)
As well as outdated BIOS, Lack of disk space is also a cause of stop 7E.

Update the following drivers

Not that I object, but mind if I ask the reasoning for the additional storage? I've a few games I can remove from the C drive and I'm well aware of the fact that my D (media) drive is massively insufficient anymore.
I intend to get a 2 or 3 TB drive down the line to replace D. But in the mean time, how much would you recommend freeing up of each?

The rest I shall try and sort out and get back.


If you suspect that disk drive space could be an issue, then does the increased activity of my D drive (which has very little space left) present an increased probability of BSOD? I know that this will be a lot more active (although mostly reads) due to changed settings in utorrent mentioned in the first post.
