First off Congrats on installing 2 Antivirus ..... Avast and MSE !!!! What were you thinking ????????
Second the startup list .... what do i say.... Are you expecting this laptop to run like Usain Bolt !!!
Third the BSOD's are Power state failure errors caused by the Authentec fingerprint drivers, memory corruption caused by the display driver (nvidia)...
Do the below first
1. Since the drivers at HP are pretty old and try reinstalling the drivers and then go to device manager and right click on the authentec driver and select properties and go to power management ...uncheck the "Allow the computer to turn off this device to save power"
2. Remove AVAST and keep MSE
3. Click on start > run ...type msconfig ... uncheck all the items from startup and only keep MSE...
4. Do a memtest
for atleast 6-8 passes for each RAM
Do these and let me know
