Windows 7 64bit freezes when moving files

I recently upgraded to Windows 7 from Vista, clean install. I moved all my important files to my external hard drive before the install. Now after installing, whenever I move large files from my external to my internal, 7 freezes up on me. After about a minute or so transferring, 7 completely locks up.

This even happens when installing new software. I've tried installing iTunes on my internal and about half way through, 7 freezes up again.

Sometimes it's a complete freeze, other times I can still move my cursor but the only way out is a hard reset. I've tried upping my RAM voltage but I've gone up +.2 volts and nothing has changed. I've never experienced freezing without either installing something or moving files. I've played games, run Firefox, Ventrilo, etc without any freezing. It's just moving and transferring files.

On Vista, I could move 120gb at once while playing games and running Ventrilo, but on 7 if I try and move just a gb and open Firefox, everything freezes on me. Is there any way to fix this?

EDIT: System Specs:
Q6600 3.00Ghz
8gb DDR2 RAM
SLI 8800 GTS G92
EVGA 750i SLI FTW Motherboard

I'm overclocking my CPU, but I can't see how this is a problem in 7 without it also being a problem in Vista.

I left 7 on idle for about 5 hours to come home to it frozen again. No downloading or anything, completely idle. Does anyone have any ideas?

I've actually been having the same problem. I did a disk check, no dice. It happens sporadically.

I haven't overclocked at all yet.
