Hi all,

Here is my problem. I have a MacPro 2.66 with 3gigs of ram, a RAID 1 setup for OSX and a separate HDD for XP Pro SP2. I use Bootcamp to swap between the OSX's. The Ram is 2x1 and 2x512 megs. The GPU is a 7300GT

Here is my problem :

I recently opened my Mac Pro case to have a look inside. Up until that time OSX ran extremely well on high resolutions using the correct DVI port on the card (the right one if you are looking from the back)

Put the cover back on, put all the inputs in and boot up.

The Dell screen suddenly displays this awful screen of lines, blocks, different colours etc.

I turn the comp off, do various tests - no problems (nb I didn't do a full hardware test). After awhile the screen boots into 1280x800 mode but nothing else. The other side works ok, but it is fixed at 1280x800.

When I go to change the resolution, the display goes into that awful screen gibberish corruption etc.

Any ideas? Methinks perhaps the card is faulty.

Also, XP Pro only recognises 2gigs of the ram, not 3gigs - is this a OS side issue. I also note under Bootcamp, certain devices are not recognised.

Thanking you.

You could do worse than pull the card and put it back in again. Could be some dust got in where it shouldn't when you opened up the machine.

Will give it a go and see.

If it doesn't work any other tips?

Yeah, make sure there's no dust or crud on the card connector strip. Is it possible you zapped the card with static electricity? What sort of flooring do you have next to your Mac Pro?

Modern electronics + static electricity do not mix! (Although they are much more resilient then they used to be, semiconductors can still get zapped)

If static did kill it, don't tell whoever is fixing the computer that
"Oh, it just stopped working, I don't know what is wrong." is what you say to Mr. Apple
