I have recently been having screen freezes and when this happens all audio is gone, my keyboard and mouse do not respond (even when i press caps lock the light does not show up). This happened before but I replaced my old WB hard drive that worker for 5 years. I bought this new Seagate last year and it hasn't been giving me any problems. I used SeaTools for Windows and tests for my hard drive showed it passed all of them. What else could this be?

When i go to Event Viewer the last thing i see before the crash is this: The application-specific permission setting do not grant Local Activation permission for the COM Server application with CLSID { a long string of numbers and letters} and APPID {another long string of numbers and letters} to the User from address LocalHost (Using LRPC) running in the application container Unavailable SID. This security permission can be modified using the Component Services Administrative tool.

The next event viewer is just saying it shut down unexpectedly because i had to restart my PC. What could this be a symptom of? This computer is 5 years old. The only thing i replaced was the Hard Drive and Graphics card a year ago. Possible Motherboard of Power Supply problem? How do I tell or find out?

well you can easily do it by leaving one stick. and boot up and see if it still freezes.
and check with the other RAM stick and doing the same process.

and sometimes reseating RAM will fix itself. in mechanical parts that has electrical flow may not function well anymore due to oxidation. esp if the PC hasnt been used for a while. so try reseating both RAMs first and see if it still freezes your PC as well.

these are generally the train of thought :
if it freezes and you can find error in your event viewer, its your drivers/BIOS/HDD.
if it freezes and you find nothing, its your RAM.
if it restarts itself without warning, its overheating/clocks too high.
if it restarts with BSOD, its a driver/BIOS/RAM.
if it shutsdown, could be your PSU/hardware.
if any of the above doesnt make sense, i check the motherboard cpu bent pins, so i can rule out a faulty motherboard. :D

you can try to do a memtest86. follow these steps here. to check your RAM.

Hmmm. The event viewer thing i posted was 20 minutes before the actual freeze. I would assume its the Ram then. How can i test which of the 2 sticks it is because it might be cheaper to buy 1 instead of 2.
