Constant Crashing with multiple .dll faults

I have been having a constant "App has stopped working" error for the past few days. It happens on every app I try, IE, BF3, TS3, Steam, Origin, basically anything. I checked the event viewer, and I seem to get alot of d2d1.dll faults, ntdll.dll, msvcrt.dll, QtCore4.dll, bf3.exe fault, nvwgf2um.dll and several others.

Ive reinstalled Win7 on my SSD and a different HD as well, still no fix. Replaced both ram sticks with known good sticks, no fix, and also replaced Graphics Card to known good Radeon HD 6870 and same issue.

Ive done the sfc /scannow, no fix.

Im leaning towards the Mobo being bad, but thats just a guess. Any help would be greaT!

Are you sure you "reinstalled" the OS? If not, follow this guide: Clean Install Windows 7

Before doing a clean install, try doing a clean boot and the run your apps and see if the problem persists: Troubleshoot Application Conflicts by Performing a Clean Startup

Of course I'm sure I reinstalled windows 7? As a matter of fact I did a clean install on 3 different hard-drives. I run Microsoft security essentials, and I'm worried about using a registry cleaner due to the fact that I've heard try cause more problems than they fix. Besides, the problem persisted right after I re installed windows 7, before I even could download drivers. So how can a registry be messed up the moment it's installed?

You say you installed it on to other hard drives? Do they work fine?

This means some hardware is being bad, but I'm afraid I don't know which (might be one of the RAM sticks).

Hey wait! How do you know the problem persisted just after a clean install? You didn't have any apps, so what was crashing at that time (just after reinstall)?

If I tried to use internet Explorer, or try to install drivers off a cd, they would crash.. I pushed through it and was able to get steam and origin installed, and it would shut those down randomly as well. And yes all three HDDs are good, and have been in use. RAM checked out fine on memtest 86.

The crashing is so bad, I cant even use the computer. Im curious if it might be a problem with my motherboard, between one of the bridges not communicating with the CPU very well. But I also thought if that was the case, then why would Windows load up just fine?

Ahh I'm pretty sure it's the standard version that comes with a biostar 880g+. I've never flashed it if that's what you are asking.
