Random restarts while playing pandora and web browsing

Alright lets have you runs some virus scans to make sure there is no infection. please use the following tools to check for root kits, and tough to remove viruses:

Windows Defender Offline

Anti-rootkit utility TDSSKiller

Try running the system file checker and a check disk:

SFC.EXE /SCANNOW
Go to Start and type in "cmd.exe" (without the quotes)
At the top of the search box, right click on the cmd.exe and select "Run as adminstrator"
In the black window that opens, type "SFC.EXE /SCANNOW" (without the quotes) and press Enter.
If the command finishes with anything other than"no violations found" run the command two more times
If on the third run there is still corruption it can not clear up run through this tutorial: SFC /SCANNOW : Run in Command Prompt at Boot

once that is done, from an elevated command prompt run this command:

Code:

chkdsk /f /r

then simply for the sake of testing please run through some hard drive diagnostics to make sure you dont have a failing drive on your hands:

Hard Drive Diagnostic Procedure

Do you use Ccleaner? If so it could be cleaning out your memory dumps.

Well that sounds good, it sounds like there may have been some system file corruption so lets wait now and see if the system stabilizes. Sometimes corrupted file systems can cause BSODs and since it seems that has cleared up hopefully we will at least be getting dump files if/when the system crashes.
