That's a spectacularly old laptop, fyi. The video card manufacturer went out of business a decade ago.

Seems like you have a pretty old laptop. I'm guessing its got a wireless B card installed internally. And wireless B supports WEP most of the time. And if you're lucky the manufacturer of that wireless card may have an update to patch your card so that it will see WAP. Otherwise you can replace that internal card or get a usb / PCMCIA wireless card that supports at least wireless G standard.

It is one of two things and that is hard drive or motherboard. To see which it is, take the hard drive out and start the computer. When it starts, tap the F2 key, if the computer gets into the BIOS and you can make changes, then I would venture to guess the problem lies with your hard drive.
