Just got my laptop back from the shop with a new SSD in it, it was going great - so much faster than the old drive, instantaneous performance - but every so often it would just start running dog slow, all CPU cores would shoot up to 100% and there would be nothing running.
I tried uninstalling my Trend Micro thinking that was the problem, doing updates, starting in safe mode etc and I couldn't get to the bottom of it. I tried getting the chipset drivers from the HP website and loading them, no difference (when the new drive went in it was loaded with a blank version of Windows 7 Home Premium as opposed to the HP Recovery option, so all of the HP specific stuff wasn't on there). I was really starting to pull my hair out.
Suddenly it dawned on me though. I have a CPU meter running in the corner and I noticed my clock speed as only 120MHz... Then I realized that when I plugged my power in the clock speed would shoot back up to 2400MHz! So then I tried looking in the BIOS for the SpeedStep thing or whatever its called and couldn't find it, and so looked in to the Advanced Power settings and found the only difference between Plugged in and Battery was the fan control changing from Active to Passive, where passive means it slows down the CPU before increasing the fan speed. Switched it to Active, and problem solved!
It must have been on Active from the HP installation as it never did that before - so glad I found the cause!
Had to share because I'm not a computer savvy person so right now I feel like a genius
