Win 7 Pro - Auto rebooting after BSOD

Win 7 Pro Pc started rebooting unexpectedly. I tried uploading the file but its 657 meg. I compressed it but its still 200 meg. How do i get it to you.

It's in a Windows 2008 R2 domain. it's a dell desktop that's been working well until a few weeks ago. No idea what caused it to start. Your suggestions are appreciated.

Yes, I just set it to create a mini dump instead of a large dump. I'm sure it will be created in the next 24 hours.

Ok I will also have a look in 24 hours :-)
Ok, the screenshot shows 2 bluescreens in the last 24 hours, causes are different. With recurring bluescreens that don't point to the same driver, normally, the first step would be to test the RAM for errors with offline tools such as the boot CD from here:
Do that, test it, no errors means it's probably not the RAM. One or more errors normally means it is the RAM.
Since you seem to have several problems and if the cause is not hardware, I suggest a Repair Install.
This should not affect your personal data or installed programs but a backup first is always a good idea.

I looked around and found dumps in the minidump folder. let me know if these point to a common problem.

Look like a hardware problem. Did you run Dell Computer Hardware Diagnostics?
Please run also an advanced diagnostics, if there is no error in the quick scan.
the 2 last ones are different - so i would start with a ram test; i use the UBCD for tthis:
Hardware diagnostic CD    UBCD

go to the download page, scroll down to the mirror section, and  click on a mirror to start the download
Download the UBCD and make the cd   <<==on a WORKING PC, and boot the problem PC from it
Here 2 links, one to the general site, and a direct link to the download

since the downloaded file is an ISO file, eg ubcd527.iso - so you need to use an ISO burning tool
if you don't have that software, install cdburnerXP :

If you want also the Ram tested - run memtest86+ at least 1 full pass,  - you should have NO errors!
For disk Diagnostics run the disk diag for your disk brand (eg seagate diag for seagate drive)  from the HDD section -  long or advanced diag !  (runs at least for30 minutes)                        ultimate boot cd             download page

**  you can make a bootable cd - or bootable usb stick

for completeness -here's how i handle disk problems :

I tried running the Dell 32 bit diags from the Dell diag partition but the diagnostics partition was deleted when the hard drive was replaced.

I download a dell 32 bit Diag iso file (cdd_1284) from dell's site but when I booted from it, it said it didn't support that Pc.

Can anyone direct me to the proper ISO for the dell 32 bit diag? Service Tag 5P3D8P1

i ran memtest on it at 6pm last night.  It was still running this and had not found any errors. attached is the pic of the results at that time. the user restarted the Pc because he needed it at 9AM this morning.

Even if memtests come up clean, it could still be the RAM. If you have spare RAM, exchange all modules. If it still bluescreens then, find out what is going on when the crash happens or resort to your latest healthy image backup.

Yesterday he was out of the office for a few hours and left his Pc logged in. When he came back, it was locked up had to hold the power button in and then do a cold start. No error messages on the screen when it locked.
looks like hardware problems -  so start swapping parts to eliminate possible causes
-Ram, PS , disk,
-or run with a minimum setup

i never use the Dell diags - they're not as good as the UBCD imo; so use it
