Old Pentium 2 if I do is single power on NO INITIAL BEEP OR SCREEN!

When do a rapid on off on then get initial beep and post in all boots correctly and continues to work!

I am suspecting a weak power supply?????

I am using Windows 98 SE with no special features but I noticed this problem when I had to install a pci addon card to give 2 usb ports since this old mother board I was unable to obtain correct usb cable to mother board.

I will very much appreciate any ideas!!

With sincere thanks in advance!!!!!
