Mysterious issue when going to sleep/hibernate

Whenever I send my Windows 7 computer to sleep/hibernate for the first time, it will act normally. It goes straight to sleep if I have hibernation turned off, or goes into hybrid sleep if I have hibernation turned on. Waking works normally. However, on the second time, the computer will not go to sleep. It sits and spins for about 5 minutes before throwing a BSOD and shutting down. My only workaround is to shut down instead of sleeping on the second time. This has happened ever since I built this computer.

Here's the odd thing, though - a few months ago I had one good streak where I could send my computer to sleep consistently, with no hardware changes. Eventually it did crash again, but I didn't save the dump before I ended up cleaning them out.

What I've done

• Here's my BlueScreenView entries. For all entries, the crash address is ntoskrnl.exe+6f4c0.

• Ran memtest - all of my memtest tests came away clean.

• I used my Win7 installation media to try and repair the OS, but nothing appeared to be wrong.

• Installed any and all updates to see if the issue was patched at some point.

• Short of reinstalling the OS, I do not think I have any other options.
