Here is the tutorial for disabling DEP.
DEP - Enable or Disable


But heed the warning in the tutorial.

You can disable it and play the games but I would re enable it after playing the games, doesn't solve the problem but in the mean time it might temporarily help.

have you tried just enabling DEP for essential programs and services and not games? look at image attached

Or might it be that secure rom is destroying my game experience?

instead of trying to work out how to disable DEP why dont you ask yourself why your getting DEP warnings, maybe you have a virus or a hacker has manipulated your system, can you do a virus scan and a malware/spyware scan?

DEP sees secure rom and anti theft programs as mallware (can't even start to guess why that could be the case) or it might have to do with a hardware failure. I read an hour ago that the DEP is directly linked with your hardware configuration so it could be an unknown hardware malfunction. The question then is. How can I find out if there is something wrong with my hardware....

try the hardware in a different machine, and if DEP sees securom as malware, wouldnt it come up on everybodys computer who plays GTA4 and mirrors edge? i have no problems with it whatsoever and heres a video to prove it http://www.youtube.com/watch?v=g3xzZTKyflc (yes bombhead is my alias on GFWlive)

Drives just drop out of exictence and also my ram kept acting crazy. 100 euros and a new motherboard later and everything runs smooth as silk. Thanks anyway for al the support.
