PC is INSANELY slow, really need some help

[HenrikM]

Hi guys. Not long ago my PC shut down and it wouldn't boot whatsoever. I've replaced the motherboard and CPU and I got it to boot into windows. However loading windows takes about double the time and sometimes 4 times the usual.

Whenever I try to open any software, it show's "not responding" for a while then opens the software.

Specs at the moment:
Win 7 64-bit
AMD Phenom II x4 955 Processor 3.20 Ghz
Radeon 6870
4x4 (16) GB Ram DDR3 (Kingston HyperX blu)
Asus M4A79XTD EVO motherboard
Seagate Barracuda 7200.10 (320GB)

I've installed the necessary drivers etc. Did a Malware scan just now and deleted a bunch of threats, still slow as fuck. Troubleshooted my HDD as well while rebooting.

Here are a reports from the performance log:

The most obvious thing to try is to format the hard drive and reinstall Windows. Have you done that? I'd certainly have done that *way* before replacing the CPU and motherboard, which are the last things to do. And after that, I'd probably replace the hard drive as aside from any viral issues, the slowness of starting could simply be it failing.

Before I replaced the CPU and Motherboard I couldn't even get into BIOS, it would just be powered on and the GPU fan would be running but the CPU fan wouldn't be. Just "dead" u know.

You likely had multiple problems. If you can boot up and it's just insanely slow, did you reinstall Windows? If the CPU/MB isn't the exact same as the old ones, you should've done a fresh install of Windows in any case.

run hdtune check your drive health. also run seatools or wd tools depending on who the drive vendor is see if they pass.

re install windows if you didnt when you added the new hardware..
reason.
the hardware abstraction layer that windows uses will still be trying to find the old hardware and load driver for it. resulting in reduced perfomance. poor stability.
if a gresh install will kill your key (due to you adding a different motherboard) then do a repair install it should renew the hal info and speed things up again.

Reinstalled Win 7 64-bit on a completely wiped drive. Problem still persists, when I benchmark my CPU using CPU-Z it's only on about half of the reference levels. Would this cause my PC to be that slow though? It's a AMD Phenom II x4 3.2ghz
