Can i upgrade my processor from 1.9ghz to 2.8ghz?

the word is optimization
or better , 99% of users see no better performance with that upgrade. A fact!
a HDD to SSD upgrade, is 10x better.
even better than that OP tell the helper what was slow first doing what.
then we work that angle,
PCs are complex what if the problem is cheap and easy free fix.?
are you gaming and dream of 1 easy fix to make a $60 game run right? oops (if yes)

that is correct, never let facts get in the way of progress...LOL a joke to the OP
not Ryan, you nailed it Sir.
in fact the BIOS must support your CPU
and the limited clock rates all PCs have
and the processor must be in the qualified
list of processor allowed.
only Acer.com has that information, not us.
and acer does (peepee)poor job of that.
unlike say ASUS.
also you will have to update the BIOS
for then newer processor to work if infact the BIOS update (details)page says it does
so call them ask them.

worse yet this is only TOY grade PC
better PC have a huge list of qualifed processors even fastest Core i7-9nnn
best is leave it alone,
the OP never once told of one APP that ran slow
not a clue at all.
but if it needs more power buy a real PC.
ok, or buy used gaming PC.

i build them.
