Windows 7: Random BSODs related to "ntsokrnl.exe+7cc40"

Random BSODs related to "ntsokrnl.exe+7cc40"

Is Windows 7 . . .
- x86 (32-bit) or x64 ? x64
- the original installed OS on the system? It wasn't prebuilt with an OS, if that's what you mean. This hard drive is brand new.
- an OEM or full retail version? Full retail.

- What is the age of system (hardware)? About 7 months old.
- What is the age of OS installation (have you re-installed the OS?) A couple days old. I just reinstalled because my old hard drive failed and I had to acquire a new one.

Today I've had two random BSODs, both apparently related to ntoskrnl.exe. The first happened when I signed in to Windows, and a couple seconds later it went kaput. When it restarted it suggested I do Startup Repair (or whatever it was called), and I restored it to an earlier (by early I mean like one from yesterday, considering this OS install is new) System Restore point. The second one just happened a while ago when I was playing Borderlands.

Well, I just had another BSOD today. This time it happened randomly while I was playing Portal 2. 2/3 times so far it's happened while playing a game. Not sure if coincidence, since this seems to just be random in general.

Anyway, here's an updated version of that one report. And there's the old PERFMON HTML in case you didn't get it from the first post.

Well, thankfully, I haven't had a BSOD since 4 days ago. Still, I'm really wondering what caused these ones. Doesn't anybody have an idea?
