Oh I guess I should have mentioned that sorry, it's a Macbook pro 2.5GHz running Lion
Thanks for the info…yes that helps us "visualize" what you have.
- How long have these lines been appearing?
- How often do they appear? For example how long can you use the computer (on average) before they show up?
- Can you be more specific what model MacBook Pro 2.5ghz it is (there have been a number of them over the years)? Or just tell us approx. how old it is.
- Have you tried booting the computer from an OS CD/DVD, or an external HD with an OS on it?
- Have you tried a PRAM reset?
- Have you tried an SMC reset?
- Have you done anything to it such as a hardware upgrade (ram or HD)?
- Have you cleaned it ever (dirt/fuzz)?
- If this computer is not too old…does it still have Applecare remaining on it?
Just a bunch of stuff to throw your way to see if anything helps. I could just say that your logic board or graphics hardware are going bad (which is very possible)…but wanted to cross some other stuff "off the troubleshooting list" first before declaring the worst!
