OK what exactly do you mean by “scrambling“?
Customer: replied 5 years ago.
the content of the page is pixelated, in largeish blocks - color intact. The screen is also freezing on and off and the response rate when I click on something is slow.

First let‘s check some things:

Please go to the Apple logo on the upper left of the screen, go to About This Mac (DO NOT Select More Info), and tell me the Version (under Mac OS X), the Processor and the Memory, it is all right there.

Then go to Macintosh HD, then go to Applications folder inside that is another folder called Utilities inside that is an application called Disk Utility. Double click on that and when it opens you will see your hard drive (usually Macintosh HD) on the left. Highlight your hard drive and click on Verify Disk on the right. If that is OK and only if that is OK click on Repair Permissions. If Verify Disk is not OK try to Repair. If Repair is successful then Repair Permissions if it is not successful let me know.
