Windows 7: Windows 7 pro 64 slow down running moderate number of apps

Windows 7 pro 64 slow down running moderate number of apps

I've been experiencing major slow down of my system and can't figure out why. Here are some details:

Computer is a HP Pavilion Core i7 Q 720 @ 1.6 ghz with 8gb ram

I'm using Performance Test to benchmark the system in different states

My baseline is Win7 Diagnostic mode (no services, no startups) - let's say that is 100% (quite fast)

Running only windows services and Eset - it drops to about 60%

But then when I'm working running several MS Office apps, Firefox, Skype and a few smaller programs, it drops to 5%!! Quite noticeably and frustratingly slow for what is supposed to be a very speedy computer.

The CPU usage is not high, memory is fine. But it is just SLOW.

Any suggestions how I can diagnose this further?

Windows 10, Home Clean Install

I would start with a complete and upadated anti virus and malwarebytes scan
Then , I would try the clean boot procedure to help diagnose
How to troubleshoot a problem by performing a clean boot in Windows Vista or in Windows 7

I would then read this fine tutorial to see if any changes are applicable.

I had done both antivirus and malware scans, plus registry cleaning to no avail.

I am now trying to run with limited services and so far its been better.

Windows 7 Home Premium 64 bit

Isn't that a processor with hyper threading?
Is it enabled in the Bios?

Hyper-threading is built in to the i7 cpu and does not have to be enabled in the bios.

Try replacing Eset with MS Security Essentials or Avast 5 with the Win7 Firewall for best performance.

Try using IE8 instead of Firefox.

Do NOT use 3rd party optimisers - they are the cause of a significant number of BSOD's. My recommendation is to start with Greg's suggestions in post #7.

Running 64-bit apps in Windows 7
I hope this isn't an especially 'dumb' question. I just upgraded to Win7, and I installed the 64-bit version. This is my first time using a 64-bit OS. My question is this: I've installed a few programs that are made for a 64-bit OS (like Cubase, and After Effects CS4), but Windows installed...
