Help! Crazy pixel mess!!!

[HydroMac]

Hi I hope someone can help. A while ago I installed some stupid screensaver from Mac downloads page, and ever since, my Mac has these dots all over the place, especially the desktop. I have attached a screenshot of a section of my desktop.

How can I get rid of this?

Forgot to mention, I have deleted the saver, ran repair permissions, disk first aid, but to no avail.

I have G4 Quicksilver with Apple Cinema Display (the old glass looking type).
OSX 10.4.10

Thanks

Have you rebooted since?
Have you changed the desktop picture?
Have you checked Login Items whether something's still automatically loaded on login?
Have you created a test user to check whether it's connected to user settings or system wide?
Have you reinstalled the system?

(If you say no to a question consider doing it.)

Hi, thanx for the reply, I have done all of the above, and even did an 'erase and re-install with my new copy of Leopard....its great, but looks so lousy due to this pixels problem...have another look....another pic...

Ive also zapped the pramm to reset the VRAM...no change. Is it that the monitor has gone on the blink? I dont think so, as the pixels move about so cant be burnt into the display..

I am sooo stumped..

during bootup try holding Apple + Alt + P+R. let it chime 3 times. . that should sort you out

Cheers CJ, but as I mentioned, Ive already tried 'zapping the pramm'.

Anyone else got any idea's?

I'm borrowing another monitor tomorrow to eliminate either the Macs disc or if its the LCD.

Cheers

The only thing I acn think of is reseting the pmu as follows :

Here is Apple's instructions (http://docs.info.apple.com/article.html?artnum=95037) for the procedure:

Resetting the PMU Chip Procedure

1. Disconnect the power cord and check the battery in the battery holder (BT1). The battery should read 3.3 V to 3.7 V. If the battery is bad, replace the battery, wait ten seconds, and then reset the PMU (refer to the next step). If the battery is good, go to the next step.

2. Press the PMU reset switch (S1) once on the logic board. Do not press the PMU reset switch a second time because it could stop the PMU chip from responding.

3. Wait ten seconds before connecting the power cord and turning the computer on. If the computer turns on, go to the next step. If the computer does not turn on, there is something else wrong with the computer.

If memory serves me the pmu switch in a Quicksilver is near the battery.

Hey Tommo, thanks for that. Before I do it, are there any complications I can cause by doing so, as documentations suggests only qualified technicians attemt this process?

Also, is the battery likely to cause this? I have no signals suggesting this. i.e. time and date are always correct?

Thanks for the help, Im just a bit precautious.
