My PC has been freezing a lot during gaming lately. I did a fresh re-install of Windows 7, which did help somewhat, but I am still freezing sometimes during games.
I have been testing the freezing by playing Fallout 3 until I get the freeze, and troubleshooting by installing certain drivers and tinkering with BIOS and other settings per advice I receive from this forum.
What I ask is this; why, when my games freeze, does the system not show a blue screen? Nor does it reset. This leads me to believe that only the game freezes, but I am unable to see anything but the image of the frozen game. The keyboard sometimes still "functions" i.e. the Caps Lock and Num Lock lights go on and off when I touch the keys, but it won't do anything, CTRL ALT DELETE doesn't register. The power button usually won't shut the system down either, so I am forced to (reluctantly) hold the power button and force shut down.
Also, the audio from the game still sounds. The music will play like normal, or sometimes play on a short 1-2 second loop. Reasons?
My guess for your freezing issues would be your computer's age. Recently, my computer died, but before then it would freeze a lot during games. It worked fine for an 8 year-old computer, but began to crash. It froze a lot. Therefore i believe a new computer maybe in order depending on the age but if it's not that old ignore my reply. Hope this helps.
to see your bsods boot the pc and press f8, when you see the boot menu theres and option there to turn off automatic restart. use this and the next time you crash you will see the bsod.
you can also use bluescreen viewer because even though your not seeing them the computer is logging them. http://www.nirsoft.net/utils/blue_screen_view.html the DL link is about 3/4 down the page.
