Lately, all my programs will stop responding, seemingly at random. This always seems to start with Firefox. It'll freeze with no warning, and I can't close the window. Also can't open task manager to end the process. If I try to close or interact with other programs, they also generally stop responding. If I try to open anything else, nothing happens. CTRL+ALT+DEL does nothing during this time. The taskbar also freezes.
Eventually, everything becomes responsive again, any programs I tried to open will appear, and the login screen will appear if I CTRL+ALT+DEL-ed during the freeze. A moment later, the problem repeats itself. This continues until I reboot, which takes an abnormally long time once the problem has surfaced.
Don't know if this is related, but I tried running a full scan with Microsoft Security Essentials overnight. When I came back, the monitor wouldn't wake from power saving mode and I had to reboot with the power button. After rebooting, I noticed I was suddenly using an extra 40GB of HD space. Ran Treesize and it reported I was using 718GB of memory, when Windows itself reported over 800.
Also had to reboot with the power button a second time, after which I logged on to a black screen and a cursor. CTRL+ALT+DEL worked, and I was able to open task manager from there, but I couldn't see my desktop or taskbar. Managed to fix this by loading last known good configuration from the boot menu.
Have run Malwarebytes. CPU usage, RAM usage and temperatures are all normal. Would appreciate any help.
