Games crash to desktop ! PSU problem ?

i personally can't help you, but i can guarantee you no one else can if you don't post your hardware details (and maybe OS?)

c'mon....

i think it is a software rather than a hardware problem. i used to use the GUI version of folding@home and had problems of games crashing to the desktop. mainly it was bf2 and also civ4 before i adjusted my ram timings. then i switched to the console version and it all works fine now.

what i'm basically saying is check to see if any programs/background services can be switched off and if they make a difference.

sry no, but i seen one not long ago. AFAIK if you only delete services started by yourself you can't do too much harm. try googling it. people have guides to this sort of thing. also use spybot for ad-aware. its one of the best free utilities.

As others have said, Google is key here. There is a free program called Process Explorer that gives ALOT more info than windows task manager. It runs out of a folder and gives info on all processes including those running in a shell(i.e. svchost). Then to turn off start-ups, run msconfig and go down the list looking for the executable file name(*.exe) Then enter them in this website http://www.sysinfo.org/startuplist.php and shut off unnecessary ones.
