after i get to the windows loading screen my mac just throws out a consistent high pitched sound and shows a black screen, i can only get into bootcamp windows when i unplug the computer and start it up with the running windows normally option. is this a virus?

p.s. macOSX works perfectly without problem.

What type of mac?

Are you sure the squeal is coming from the mac and not the monitor. Some monitors if you send them an unsupported resolution, they show a black screen and squeal like they're going to die.

Probably not a virus.

I've got an intel 24" imac, cant tell if its the mac or the monitor since they r the same thing lol, i dont think its the resolution tho, it has been fine for half a year until i installed assassin's creed II on it, but then it didnt happen right after i installed it, it happened after like a few days after.
 
no, it worked perfectly until, i think after i installed the crack for assassins creed 2 lol
 
I have the same problem. It's only in Windows - both when I boot directly from the bootcamp partition and from VMware. Has anyone figured this out?
 
Old thread, but the problem still lingers, it seems. I've also been experiencing this problem since right around Thanksgiving 2021, both with Windows 10 and Windows 11 on a 2019 27" iMac. I've tried various things that were suggested across the internet, but of course it always comes back and sometimes it is harder to remediate than others. I tried installing Windows 11 and that seemed to initially fix it, but then it came back twice more. The most recent incident had me reading a message thread over on Reddit that seemed to be suggesting that resetting the PRAM might help -- that is, hold down Option, Command, P, and R on reboot until the Mac chimes again. That was what fixed it, this time.

It was suggested in the other thread that the problem is specifically related to swapping back and forth between Windows and MacOS. I'll be keeping track of the issue to see if it reoccurs, but my latest reboots back and forth have not yet triggered it again... so it seems to be a very specific scenario that causes it, possibly something to do with the Windows Bootcamp Control Panel.
