Woes after compressing C drive

[jivedadson]

I hope you folks can help me. I will describe the symptoms, then what I did shortly before they started, which may have caused the problem.

My computer becomes unresponsive. The light that indicates the disk is being accessed comes on solid. Cursor disappears. Ctrl-shift-delete is slow if it works at all. Cannot bring up process monitor. Cannot shutdown or restart. Must turn off power.

So far when this has happened, always I have been watching youtube videos in HTML5. It happens using Firefox or Chrome. Of course, I have no idea whether watching videos has anything to do wit it.

The most recent restore point I have is from a year ago. I use automatic updates, so I am assuming more recent restore points have been lost.

Shortly before this started, I did something that I regret. I compressed the entire C drive. (The process got interrupted once.) After the trouble started, I set the C drive back to uncompressed. Both compressing and un-compressing took hours. I have run check-disk, and it came up clean.

So here I am with an unstable system and no recent restore-point. What to do?

Windows 7 Home Premium 64 bit, service pack 1
Gateway SX2370, AMD A6-3620 APU with Radeon HD Graphics 2.20 GHz

Back up your data and restore the system to it's factory new state is what I'd do.

Greg's response much better than mine!

Can't provide much help as your System Specs are meaningless.
