I have a Power Mac 6500/225 that doesn't boot up properly. Whenever i restart it or shut down then start up i get the gray screen but the boot process just stops. The mouse pointer is there and moves so it isn't frozen but i never get the smily mac icon, or any icon for that matter, just a plain gray screen and mouse pointer. However, if I unplug it, wait a bit then plug it back in and turn it on it will usualy boot up just fine i don't notice any problems while it is running. Any thoughts as to what the problem is? BTW , I have zapped the p-ram, replaced the mother board battery and run nortan disk doctor and disk utility. Nothing helps.
