Hi fellow LTTers! On Christmas 2012, my father bought me a prebuilt Medion Akoya desktop PC (precise model: MEDION AKOYA P5394D MD8451, here it is on a French retailer website).

The thing is that since two days my computer suddenly became reaaaally slow. Using Ctrl+Shift+Esc, Task Manager took 200 seconds to load and VLC plays videos after 3 minutes. I had to wait a full minute staring at a black screen when I launched CS:GO (it even crashed later during the game). I also had some UAC prompts simply timing out without me being able to see them. Once loaded, the programs are smoothly running, so I guess they are queued but the computer "forgets" to launch them in time.
I don't really understand how is it possible for a computer to instantly become slow. My hypothesis is that either the HDD or the PSU is faulty: however, I have no spare parts at home and I'm a little low on cash. What can I do to turn it back in its glorious days' state?
