My computer became more slower and laggy after I upgrade the RAM.
My computer has 2GB RAM and I upgraded it to 6GB RAM, which means I added 4GB RAM.

Before I upgraded it, my computer runs normally, without any lag and not slow.

And after I upgraded it, my computer runs slower and laggy.

I've tried to take out the 4GB RAM (the new RAM). My computer still slow and laggy. Even more slower.
I've tried to clean with CCleaner, fix the registry errors/issues, defrag the C: .
It doesn't do anything, and it's still slow.

My computer specification is :
Windows 8.1
Intel® Core™ i3-4130 CPU @ 3.40 GHz (4 CPUs), ~3.4 GHz
Intel® HD Graphics 4400

Can you solve this, please?

:welcome:    Lance Versailles,


Most likely a coincidence that the computer slowed down when you added more ram.


I've tried to clean with CCleaner, fix the registry errors/issues, defrag the C:



Using CCleaner to get rid of unneeded/orphan files etc is fine but the average user should not go anywhere near the registry and while defragging a HDD every few months may help with performance it will not resolve the type of behaviour that you describe above.


Note, you mention defragging the C: drive but no mention of the type of the drive itself, if by any chance it is an SSD then it should never be defragged and doing so will damage it.


Post back if you are still around and we will take a look for you.
