Essentially, long ago I was stupid enough to run a trial of a registry fixer. Through the test time of, the battle of computer viruses here and there, my 6 month old computer has essentially turned into a brick.

My two main problems being:

* DEP seems to be preventing me from opening any browsers as well as disallowing me to write files onto CD's, USB's, etc.

* Now, approximately 30 min. after I try to use an internet using program such as uTorrent or play a computer performance demanding game, I get a BSOD.

The BSOD being:
driver_irql_bot_less_or_equal

STOP: 0x000000D1 (0x000000000000, 0x000000000002, 0x0000000000000, 0xFFFFF88001A8BEE0)

tcpip.sys - Address FFFFF88001Q8BEE0 base at FFFFF88001A01000, DateStamp 4e83eb7f
.
Specs:
AMD Radeon HD 6870

kingston 1333mhz 4gb ram
Windows 7

Tcpip.sys is a network driver, but I doubt if this is the main cause of your troubles. You have damage to the Windows installation from malware. Can you re-load Windows fresh? What antivirus program were you using?
