I had to reinstall W7 after repeated BSOD shutdowns. It seemed to be OK for a while but after installing hundreds of windows critical updates the BSOD appeared again. A system restore got things working. I have gradually installed updates in batches until today I again got a BSOD. I can do another System Restore but will be left without a load of Critical Updates installed. I'll probably live with that but be extra vigilant. However the problem recurred after replacing MSE with AVG and I'm not sure if AVG is the problem! After the last crash Windows referred me to a temp file in AppData but since the reinstall I no longer have that showing. If I remember it used to have program data files that resided under Users. It also referred to dump files but they cant be opened. I have the Blue Screen View program which indicates that a driver ntkrnlpa.exe is the cause. Any suggestions?
The BSOD closes too quick to see an error code.
Blue Screen View: 3 Parameters -
0x00000061 0x00000000 0x807c0120
Caused by ntkrnlpa.exe address ntkrnlpa.exe+dedd8
It hasn't crashed since I uninstalled AVG but MSE is taking ages to download updates.
The bad publicity about SE was why I 1nstalled AVG. I had used MSE for years without problems but I carried out a daily scan with Malwarebytes as well.
I suspect my problems with W7 occurred after installing AVG and replaced it with MSE as a temporary measure. I'll investigate other free AVs once I complete my W7 Updates .
