This is a carry-over post from the old forum.
Originally I thought this issue was a video card issue but now I'm not so sure.
On the advice of Flurk--2008, I set my colors to 256 but this did not resolve the issue. Then I got a pointer to verify I was not having any bulging or leaking electrolytic capacitors. I verified that this is not occuring.
Looking for advice on next steps such as tools/software diagnostics or other things to try.
Restating what's going on:
My G5 has been starting to act up again.
Problem started 3-4 weeks back where on startup i'd get apple splash screen / spinning bar or loading / then screen gets the fuzzies white/gray on top with black background, seems to roll down the monitor then it just shuts down
searched the mac forums and based on findings, I removed all I/O devices except kbd & mouse. still had same problems, then Reset PRAM and this got me further still lots of horizontal lines but I was able to bring system up and lower resolution.
now I have a semi functional machine most of the time but 800x600 stretched on this is not very fun.
still getting intermittent horizontal noise & really need to get resolution issue resolved.
Latest behavior is that the system is shutting down more frequently.
Any ideas?
Joe
