hello, Today i modificated DEP and since then if i restart windows all my apps crashing cant open anything. The original setting was: Turn on Dep for essential Windows programs and services only and i modificated it to: Turn on DEP for all programs and services except those I select: and i added 2 games exe files (did this because i read on several forums that the game crash to desktop with no reason if i dont do it (and it was crashed for me making the game unplayable) ) So if i start my computer and windows start i get Application Error - 0xc0000005 Usually with windows MSN, skype etc programs startup automatically, but now not and get the above mentioned error. At all i cant start Any of my programs or services, because get the same error. Tried the system restore in Repair Computer, but not helped at all. Googled for that but not found any real solutions. And next to my cursor the loading circle thing is always shows and blinks, like it trying to load something. It never stops. At the moment im really hopeless. Cant do anything. Really looking for some expert who can help me ! Thanks !
