My computer has always been very fast since I formatted and reinstalled Windows 8 x64. Yesterday I did some things - the result is that my computer became VERY slow.
- Game performance is greatly decreased - even Doom 2 stutters.
- CPU and disk performance is greatly decreased - compiling my C++ projects takes 3x the time it took before
- Applications and explorer generally feel slower and sluggish
So, what did I do yesterday?
- I bought a new microphone, and plugged it in
- When I plugged the microphone in, I moved the case around (gently)
- I installed Windows 8 x64 on my old laptop, logged in with my Microsoft account, and the setting synced between my desktop and my laptop. This is when I noticed the slowdown. I used system restore in order to go back to 28 February - this restored the original theme I had on my desktop. I disabled syncing on my desktop. Slowdown was still present. I cleaned the computer using CCleaner and Glary Utilities. Slowdown was still present. I booted in safe mode, cleaned Startup applications, Automatic services and unused drivers in the Device manager. I updated my video card drivers to the latest version. I ran Windows Update. Slowdown was still present.
- Went to bed.
Today, I turned off the computer, unplugged all cables, opened the case, cleaned up the inside, checked if any cable was not connected properly. I plugged everything back in. Slowdown was still present.
I don't know what happened, and I don't want to format my computer again - there has to be a solution to the problem.

I noticed RAM frequency (MHz) was way lower than expected. It should be 1600MHz, but it barely reaches 600MHz. I tried removing 1 stick of RAM, changing places, checking BIOS information. Still a lower frequency.
I tried a completely different stick of RAM (taken from another computer), that should be 1333MHz. It barely reached 500MHz.
Is it possible that an hypothetical electrical shock generated when I plugged in the microphone screwed up the motherboard? The microphone wasn't working right at first - I had to open it up and touch the cables to get it to work.
