Hi Skenteris Kostas,
Error code 50 is related to the I/O Busses: PCI, USB, ISA, ATA, etc,
These are some recommendations for this issue:
- Test the system out of the chassis, minimal configuration please. (Motherboard, processor, power supply, 1 memory stick and video card)
-This document lists troubleshooting tips if your computer does not boot up properly.
Thank you for your concern and answer. I have already tried booting the motherboard out of the chassis, with one processor at a time, with different video card, with a couple of Ram module in various ram slots, but nothing seems to be working..I'll give another try soon..Thank you a lot! If any other idea comes up I would be glad to hear it. Have a nice day.
