Gateway froze and wont boot

[mdegood]

Hello all,

Ok here it is, have had this gateway performance 500 since birth. Always a fast (then) and dependable machine. It's running a pent III slot A 500 mhz. I had reformatted and install new OS a couple of days ago and all was well. Had computer on and running last night, left it alone for @45 mins. came back to find desk top froze, had to hold power button to shut down. On reboot all I got was the start of the boot screen. would show the tnt2 video card and that is all. Hard drive light would come on for @10-20 secs then go off, screen would go blank.

I put a known good hard drive in, no joy. checked the fans, all running. removed ram one at a time, no joy. replaced hd cable, no joy. removed all non-required pci cards and drives, no joy.

I would understand that maybe it could be the cpu, if I had been working on it and zapped it, but to freeze up and not boot even into bios screen.

any and all help sure would be great.

Thanks
Mark

Could be power related. Remove the memory and boot, do you here the mem beep code?
