Purchased a refurbished laptop and mesh items shoot random spikes?? Any ideas on how to fix this?

Its not the entire screen it seems to just be the mesh attached to my body.

Spikes Going Off to "Infinity"

If you are using ATI/AMD graphics and drivers, certain non-rigged mesh items may display as a long stretch which points to the region coordinates 0,0,0. If you observe such long spikes, then try:

• Ideally, you should update your Catalyst Drivers Version 14.4 - or better yet, one of the latest 15.x drivers, if they are available for your graphics card. Visit this page more on this.
• Otherwise, go to Preferences - Graphics - General subtab - disable Hardware Skinning. (This may result in a loss of FPS. Turn on the Statistics Panel using Ctrl Shift 1, disable Hardware Skinning and monitor your FPS.) As this bug affects some non-rigged mesh items, and not all, you may determine that disabling Hardware Skinning is not worth the loss of FPS.
