Please test your memory using MemTest86+ if uninstalling AVG doesn't help.
Run MemTest86+ to analyse your RAM. MemTest86+ - Test RAM - Windows 10 Forums
MemTest86+ needs to be run for at least 8 passes
for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for zero
