There are a lot of causes of a STOP 0x0000007F: UNEXPECTED_KERNEL_MODE_TRAP
Usual causes: Memory corruption, Hardware (memory in particular), Overclocking failure, Installing a faulty or mismatched hardware (especially memory) or a failure after installing it, 3rd party firewall, Device drivers, SCSI/network/BIOS updates needed, Improperly seated cards, Incompatible storage devices, Overclocking, Virus scanner, Backup tool, Bad motherboard, Missing Service Pack.
First, I would say if you are overclocking any hardware, please stop.
Make scans with the following:
Kaspersky TDSSKiller -
TDSSKiller Rootkit Removal Utility Free Download | Kaspersky Lab US
ESET online scanner -
Online Virus Scanner Eset
Zone Alarm Firewall is also a possible cause of your BSOD's.
