BSOD after software/program install or Windows Update

After installing a fresh copy of Windows 7 Pro 64bit, my Media Center PC is crashing either every couple of hours OR after a new program installation OR windows update. At first AVG antivirus was installed, I removed AVG and replaced with Windows Essentials. Seemed to lessen the hourly BSOD, but still having issues installing new software.

Since this PC is feeding every single TV in the house with Live TV it is getting annoying.

Thanks for any help!!
