I left my PC in a perfect working condition 2 weeks ago.I came back today after the easter holydays and i realized that my PC is not booting at all.Blank screen i get the 52 Post Code.Thinking that it's smthing with my RAM sticks or with the slots i started to test them 1 by 1 in a diff slot.Nothing.Same 52 post code.Reseted my bios several times, took out the battery, nothing helped.Could it be that the bios got corrupted or smthing?
