Now everytime I boot it gives me the error:
ERROR
Warning: IRQ not configured - PCI
Bus: 00 Device: 13 Function: 00
ERROR
Warning: IRQ not configured - PCI
Bus: 00 Device: 0A Function: 00
Press F1 for IBM BIOS Setup Utility
So I entered the BIOS by F1 and I reset the PCI config to default. When it reboots it works fine. However the clock is reset and if I turn it off and unplug it, the same thing happends again.
The fact that it resets the clock and starts again each cold boot made me think it was the CMOS battery so I got a new one. Same problem happends. Any suggestions? Thanks for your help.
