BSOD - Running out of ideas

I seem to be forgetting when these crashes happen.

What is the make/model of your PSU?

Do you have another video card you can try? Try borrowing one from a friend or another computer.

...Summary of the Dumps:

Code:

Built by: 7600.16617.amd64fre.win7_gdr.100618-1621

I have to suspect some sort of video memory corruption. Try taking the computer to the local PC shop and having them test your card.

Did your computer have the BSoDs since you built it?

If not, what software and/or hardware was installed before the blue screens started?
List everything, even if it seems un-related.

Did it start out as very seldom and slowly increased or start all of a sudden?

When you updated the BIOS, was this around the time the blue screens started?

Check your graphics card manufacturer site for FW (FirmWare) updates.
This has to be done separately, it does not come with MOBO BIOS or any drivers.
What is the brand and exact model numbers of your graphic cards?

When you ran memtest86+ was this with all the RAM cards installed?
How many runs did you do?

Do you have 6GB RAM?
What size are the cards? (3X2GB, 2X2GB and 2X1GB?)
How many cards are installed? (3 or 4?)
Did you buy these all at the same time? Same brand and P/N?
Have you ever bumped the north bridge voltage?

Check everything in the case for loose connections, possible grounding points.
Re-seat all cables.
This could be a grounding issue.

Check your MOBO for bulging or leaking capacitors.

What version is your MOBO?
P5E3 Deluxe?
Version E3468 or Version E3366?

If anything here doesn't help then you should do a bench test, take everything out of the case and set it up on a table.
PSU, motherboard, one RAM card, one graphics card and one monitor.
Take everything else out, no sound card etc.
Test if it will load BIOS.
Add HDD, see if it will run, test for BSoD.
Then add one component at a time until you get the blue screen.

Edit:

Just noticed this:

I have now uninstalled Rainmeter and disabled driver verifier.
I have also run another sfc /scannow and have attached the log as it said there were errors it was unable to repair.

You should resolve this issue before doing any hardware tests.
Try a restore point, run sfc /scannow, if you get the same message, choose an earlier restore point.
If this fails to resolve the problem, try a Repair Install.

Sirik, Dave's advice is spot on. You must get your system files properly working.

Among other things, the bench test will eliminate any grounding issues, you can save this step until you have checked everything else.

You should follow Jonathan_King's advice and find a way to test with a different graphics card.

If you get another crash, uninstall Windows 7 Universal Theme Patcher, check if you still have crashes.
Have you checked for an updated version of this program?

You need to eliminate any possible causes of the crashes.
