Windows 7: BSOD randomly on fresh Windows install, BAD_POOL_HEADER and others

Hey guys. I've been running this computer for about a year and a half now problem-free, and all of a sudden BSODs started popping up like white on rice. Typically they're either BAD_POOL_HEADERS or CDD.DLL, but there have been a couple more I didn't catch the full name of. I've also gotten the whole "file may be corrupted, checksum doesn't match up" message. I figured I just needed a nice clean install of Windows, but even after reinstalling the BSODs continued. I will say that they happen a lot more frequently playing vidya games--the first occurrence was during Borderlands, then CS:GO, the Binding of Isaac--but they happen just browsing the net as well. Any suggestions? Thanks in advance!

Also, I should probably add that I've already uninstalled DaemonTools--immediately after posting that .zip, as a matter of fact.
