After solving some BSOD problems with my computer, I was confident that my computer was back to normal. I returned to my normal PC habits.
I was playing Batman Arkham Asylum and, during a cutscene, the screen froze and the speakers produced a cackling sound. I could not ALT+TAB or CTRL+ALT+DELETE out of it so I shut down the computer manually. Since then I have been unable to restart it. Thinking it might be overheating, I've let the computer rest for an hour (this worked the last time it wouldnt restart) but it still doesnt boot up. All the components and fans seem to start up but nothing is displayed.
I thought it may be a faulty graphics card (this would have explained the previous BSOD problems I had which were graphics related) but then I realized that the computer doesnt make the usual beep when booting up nor does it make that beep to signal something is wrong. What is the issue?
I am trying resetting the CMOS to see if that works but I don't think it will. Is it really possible that a game can cause this much havoc? These problems seem to arise when playing this game so this leads me to believe so...
EDIT: btw, I have run graphics stress tests (furmark), an HDD diagnostic test (HD tune) and some CPU and RAM tests (Prime95, though admittedly only for 15 minutes)
