A friend gave me the above machine after local repair shops gave up on it. It will not boot at all, no fan or post, only shows power available led. I laid it aside for 3 months then thinking I would try to repair it plugged in the power, pushed the switch and bingo! it booted up after ScanDisk and seemed to run properly allowing me to remove some junk off the HD and defrag. At the end of defrag at "close" it locked up completely -- no cont-alt-del or power off. I had to pull the plug to shut down. I again tried to reboot a get nothing! Only a power available led showing. The machine has a AMD 475 k2-6 cpu, 60 meg mem, 4 gig hd and win98. I tried reseating the cpu to no avail and can see nothing obvious wrong. Can someone please point me in a direction to look for the problem?
