No but it does not Beep every time ... The errors you where getting referred to the USB Ports and sleep problems the Chipset Driver Update should have taken care of the USB Ports ... I looked at your Model Number seems a lot of them Computers had problems with the PSU ...
What's the PSU?
Oh okay. Well, it's still under warranty. I hope that's not the case here.
We will need to do more testing before the end of the year to figure out what it is. Because, if it is the Power Supply, then Acer needs to fix it.
Can do Ram Graphics Temperature Tests etc Can also do PSU Voltage tests ... Can start when you get back from Church ?
Okay. That will work.
This is what I found online about Power Supply Issues. The computer doesn't make a whining sound, but the monitor does.
The monitor has always made a high pitched buzzing noise. It gets higher on certain screens of the display.
