Computer boots to desktop, then freezes. Maybe a Graphics problem?

Running Win 7 Home Premium 64 bit on a Lenovo Ideapad Laptop

Note: I'm not particularly tech-savvy, so I apologize if this seems incoherent to you.

Two days ago, I was trying to make my monitor display just a little less contrast, so I opened a utility called Intel HD Graphics that I found on the bottom right toolbar, and it had sliders with which I fixed the problem. But then I noticed a slider called "Hue", and by moving that quickly from side to side, my monitor went from blue to green to pink to yellow and back again, what can I say, I'm easily entertained.

Anyway, the computer froze up, and I had to rude boot it. From then on, I would start the computer, and it would look good, like it would start for real, and I would even see some icons on the desktop, but then it would freeze up and I'd have to rude boot it again. It still works in Safe Mode.

Any help?

In Safe Mode, open a Command Prompt, type chkdsk /r and press Enter.
You will see a message like this:

>chkdsk /r
The type of the file system is NTFS.
Cannot lock current drive.

Chkdsk cannot run because the volume is in use by another
process. Would you like to schedule this volume to be
checked the next time the system restarts? (Y/N)

Enter Y then reboot normally. Let chkdsk run to completion. This can take and hour or more.

See if that fixes the problem.
