I have an Acer Aspire 5100-3357 Laptop that squeals when it boots up. If I push some keys, and it really doesn't matter which, the squealing goes away and the computer boots to windows.
A little background info: When I first had this problem a few days ago, it was even worse. After the squealing stops and the computer boots up, the cursor would take off or skip a letter while typing a document or if in text box of any kind. I removed the keyboard and blew it out with my air compressor and it worked great for about three days. Now the squealing is back, but the typing is fine.
I'm not exactly positive the squealing is the keyboard, but it seems to be.
Thank You in advance!
