With a very gloomy face, I headed over to Goris electronica today, to get my PC fixed. Phoning ahead, I was told fixing my PC could take as a long as a week. However, they were able to fix it in 10 minutes, replacing the CPU fan.
I was afraid the CPU had burnt out, but it seems all's working fine: I'm typing this now, no?
Kudos to Goris.
