I am running Win98 on a KT133TX board. When I turn on the computer the Cpu fan is working and also the other case fan too. I can also get my cd-rom to open. So I know there is power. I do not hear my hard drive spinning or my see my floppy light go on when I have a floppy disk in there. I've taken out all the PCI card and even diconnect the cables and I still don't get a post. I've swap hard drives and video cards too.... Any solutions?

try temporary switch of cdrom and hard drive data and power cables. Also, check in bios if the hard drive is detected.

read your motherboard manual there is a reset for the cmos on the mb pull the powercord and move that (reset) in position and have it there for about 6sec then try to restart your computor when doing so hold down the delete key that will hopefully get you to the Bios screen there look at your processor settings make sure that they are correct if not change to the correct values "if they are" then u could try to turn down the setting ,, example u have a p3 500 that u run at 100Mhz then choose the option 500/66 then press F10 and c what happens if the computor starts then i would think that there is a problem with your memory .. then get Doc memory tester at http://www.simmtester.com/PAGE/products/doc/docinfo.asp and run that ( it will take wery long time ) and u dont want to c errors of any sort in the report good luck

try putting some known to be good ram in it and retry, sounds like a bad ram problem.

If you have pulled all the cards and disconnected all the drives and don't get a POST beep, your motherboard or CPU is probably defective. But just in case, reseat the power connector to the motherboard and also the CPU.
