You are a marginal on RAM, see
The processor is fine though, so you might well benefit from some more
RAM if you can fit it.  It might dramatically speed up your system.

I don't know whether RAM shortage might cause this sort of issue or not.

Sorry, I can't help with that.  You might be better to start a
separate thread with a meaningful subject for that.  Some readers just
skim through the subjects looking for those that interest them.  Your
subject line is not very helpful.

Following on from what others have said, did you upgrade in one go or
in steps?  If you upgraded in one go (and I don't know how you could
do that) then you may be in trouble.
