Hello

I own a 4320s HP laptop which I bought in 2010.

Recently, It started to work slowly So I formatted the hard drive and re-installed my legal copy of windows 7. The laptop ran better after it, but it still doesn't run as fast as it should.

It is especially noticeable when trying to play a video from my hard drive or Youtube. It just won't run smoothly.

It can't be viruses or malwares because I erased everything when I formatted and I installed softwares from a reliable source only.

I ran a series of tests on my hardware such as: Memtest, Hard Disk Sentinel, WD DATA LIFE GUARD, AIDA64, MHDD. All tests showed no malfunctions in my system.

Any ideas of what can be causing this problem or how can I speed up my computer to run videos smoothly?

Thank you,
Roman
