Hi All, Just built a system for a friend.AMD XP 1600+,the rest is not high end so the parts aren't mentioned.The idea was to build a good cheap upgrade from a K6-2 system.The Mobo is a K7s5A Elite(ECS).Everything went fine,Win2kPro got installed and all peripherals as well as cable modem work perfectly.The problem is I can shut down the comp but it gets no beep codes at all when I reboot and just churns away between the cd rom and cdrw with the hard drive light staying on.When I reach around back and shut off the power switch and turn it back on and then press the power switch on the front of the case it boots up no problem.It will restart ok.Oh yeah I know I shouldn't shut the switch off while it's spinning.I've checked the lead wires,and changed and removed pci cards,reinstalled windows start up files.Anyone ever run into this problem before?I have but it has always been like polarity on the lead wires or wrong voltage.I have an idea it might be the power supply or one of the switches.
