2011 Macbook Pro running Bootcamp Windows 7 Home Premium 64 bit freezes randomly, beeping crackle sounds

Question:
Hello, my 2011 15in Macbook Pro running Bootcamp Windows 7 Home Premium 64 bit experiencing hard freezes randomly, sometimes with loud, beeping crackle sounds.
This can happen while playing games or while simply browsing the web, but it's only happened
on the windows side of my computer.
Not in Mac OS X.
Sometimes the computer goes into sleep mode and can't be woken up, other times it just freezes with the loud distorted sound.
It happened once shortly after I reinstalled windows on the computer.
I considered
faulty RAM as I have recently upgraded from 4 to 8 gb and attempted to test the computer with memtest 86+, but the test interrupts and halts almost instantly after the test begins.
Running Apple Hardware test for 3 passes brought up no memory errors.
I've
also run chkdsk and sfc /scannow and everything has checked out.
I've also noted that when the computer freezes when it is plugged in, removing the plug causes the computer to turn off.
If it is not plugged in when it freezes, plugging in the cable and removing
it also turns off the computer.
I've also run RegCure to see if any registry faults could be the culprit to no avail.
Any help would be greatly appreciated as this issue has proved frustrating resilient to all my attempts so far.

Boot into safe mode with networking and see if the issue persists.
 
If the issue does not occur in safe mode, boot your system in a clean boot state (in normal mode) to troubleshoot the issue.

Shut down the programs which are running in the background - 2011 Macbook Pro running Bootcamp Windows 7 Home Premium 64 bit freezes randomly, beeping crackle sounds


Part of the reason why old PC take so long to start and various errors is because of all the applications you've installed. Reducing the number of applications which start-up when Windows boots enables you to get to the desktop faster and increases the memory available.

At the right side of the taskbar, click the arrow to display the notification icons. Each is a program that loads with Windows. Some are essential - antivirus software for example - but others may not be. Right click each one and if there is a Settings menu, select it and turn off the option to start automatically with Windows. Some programs, such as Google Drive, can be manually started when they are needed instead of running all the time.


Reinstall your Windows


When you have tried the above methods but can't seem to fix your problem, you can reinstall your Operating System and install a "clean" copy of Windows onto your computer again. But this should be the last resort to fix your problem, as this will completely erase everything on your hard drive and it will take you a lot of time to reinstall all your software back to your system. It's very necessary for you to back up all files, pictures and personal information before you do that.
