BSOD in normal and clean boot, runs fine in safe mode

Hi, after connecting and disconnecting some external HDD using USB to my pc, BSOD keeps showing constantly after 5 minutes from booting to windows .

I checked RAM, and it urned out to be in good shape, then i tried Registry cleaning, but nothing changed .

It works very well and stable under safe mode only, and my best guess that it's my HDD which is not in good shape, but that doesn't explain how it works fine under safe mode, it supposed to crash also, right ?

I have :

Pentium 4 3.00 GHz
4 GB RAM
Nvidia 8400GS

OS : Windows 7 Ultimate 64bit
Sorry for my bad English

Here is my SF_Diagnostic_Tool results

But i don't have an activation problem, and i have the windows disk from an HP laptop is used to have so it's legit .
