If your laptop sounds like this in the video then yeah it's a failure/corrupt.
Bluescreen could be or most likely a bad ram. To test for bad RAM download Memtest+ (32bit=86/64bit=64 for Operating System)
You must login or register to view this content. You will need to burn it to cd or just create a bootable usb with ISO file.
This test can take hours to find. Also remove extra RAM to get accurate test. Requires you to open RAM slot on bottom of laptop if there is one.
