everything else on the computer looks fine.
its weird. histograms show in devolop module, and the folders show on the botttom.

Your monitor profile is corrupt. Ideally, you should get a hardware calibrator and calibrate your monitor.
As a stopgap measure until you can afford the $100 for the calibrator, go into Control Panel/Color Management and set your profile to "sRGB IEC6196-2.1", which is the vanilla sRGB profile. This won't give you "correct" colours, but it will at least let you see your images in "reasonable" colours. ![]()

It might be that the monitor profile is broken, try changing it to sRGB and see if it fixes the problem.
If it does, it is not a permanent solution but confirms that the monitor profile is the problem. You will need to create a new monitor profile with a hardware device like Spyder one or Eye one display. See the screen shot for the lcation of the monitor profile.
