Please remove Avast and use Windows Defender as alternative.
Programs that claim to update your drivers install either the wrong or corrupted drivers.
If you have installed any driver with Driver Booster 3, please remove them as it may cause trouble.
An easy way to get remove these drivers is by using a restore point prior the installation.
Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 10 Forums
MemTest86+ needs to be run for at least 8 complete passes
for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero
errors here. Even a single error will indicate RAM failure.
Make a photo of the result and post it.
If errors show up you can stop the test, remove all sticks but 1 and test this single stick in each slot for 8 passes or until errors show, switch sticks and repeat.
If errors show up and you see them a lot later, no problem, the errors don't affect the test.
