well all my problems are solved...!!!
All I had to do is delete the CMOS by hardware... it just happened.. I was playing around with the multiplicator in my BIOS because I wanted to run my C Athlon at 1400MHz and 100Mhz FSB (some heat issues) but I guess that's not possible... well the computer would not start anymore so I had to do the cmos deleting via jumper... that was fast and solved a bunch of problems!!
