I have a HP Pavilion 6540C with Windows 98 SE on it. My system will not bootup after it is shutdown. This happens when I do a normal shut down. If I need to bring the computer back up it won't start. The computer light comes on but that is it. I have to wait about 10 to 15 minutes before it will bootup. I get nothing on the screen,(and it is not the monitor) I can't get into safe mode, the bios or anything. It doesn't matter if I have been on my system for 1 minute or 4 hours it does the same thing. I have wiped my harddrive and reloaded 98, I tried to upgrade to Windows 2000 and it still does the same thing. I have done the scanreg, disable things for the startup menu, system file checker & etc. There isn't a Bios upgrade. I have installed new RAM and a new battery. Can anyone Help?
