I've been having a problem for months now where my mouse will still move but the background freezes and I am unable to click anything or ctrl-alt-del. This doesn't happen when I run games or applications, but rather randomly when I do things such as install or surf the web on Firefox. Sometimes it happens on the login screen and I cannot enter my password to log into window due to a frozen desktop. I cannot reproduce the problem reliably because no specific thing I do causes a crash. Eventually, the system inevitably BSODs always with the same stop code 0x000000f4. This computer is a laptop.
Video Card: NVidia GTX 580 M 2GB
Processor: Intel Sandy Bridge i7 2860 QM @ 2.5 gHz
Memory: 12 GB at 1600 mHz (2 sticks of 2GB, 2 sticks of 8GB added after purchase of the computer)
Hard Drive: 750 GB 3gb/s SATA HDD + 120GB Corsair 6gb/s SSD added after purchase)
I am going to run mem86 ASAP, but some of my research seems to suggest my hard drives are improperly configured. I boot off of the SSD, and when I installed it I simply plugged it into the second hard drive bay and booted windows 7 onto it and continued to use the HDD for storage. Tips on how to fix this? It's quite frustrating and has been persistent for a while.
The code may indicate that the registry is in error, but you have to ask why the registry is in error. The chances are you have a memory problem. Download and run memtest86 for at least three passes to test your memory.
