I ordered an SSD now, and got it today. Windows is giving me now messages every 5 minutes that the disk in question is faulty. I wanted to buy an SSD anyway at some point, so I will move my C: partition to it, then use that one as a replacement for the dead HDD, and just use the SSD as C: partition. I won't have time to build it in this week, but it will be the first thing I do next week, probably Monday.

I bought a Samsung 840 Pro 256, seems to be reliable and one of the fastest SSDs on the market. It got best reviews everywhere, only negative point it almost got everywhere, was the a bit too high price, but it's not that much more.
