Yeah, I kind of made the mistake of installing the wrong bios update on my motherboard... My fault though, but I get the fans spinning, and everything has power, but I don't get a post screen or anything, and it happened after updating my bios with the wrong ones.Well, here are the specs.

CPU-AMD Sempron @ 1.5 ghz, read as Athlon XP-M @1.5 ghz
1024 ddr 333 mhz
Syntex KT266AD Via chipset
ATI Radeon 9000 pro
Sound Blaster Live!24-bit

Basically, what can I do to get my computer back? How can I get the old bios back on it?

Forgot to mention, there are no beeps either.

Hello Vbetts

Welcome to PC Help Forums

Well unless I'm very much mistaken your in the soup.
Our tech team may have other views of course, please hold on.

Well, anything will help right now. But, I'm not on the ball today, because I forgot one more thing. Rofl

But, the bios I installed were the KT266A bios.

You may be able to reflash it with the correct bios. Maybe go back to your mb mfgs website and get the correct bios, or check here and see if its listed. Also it would be a good idea to get one of the bios utilities , so you can copy your existing bios next time, in case of a snafu you can reinstall it. ;
Flash BIOS upgrades for almost every motherboard.
Also, you can check here for a bios chip already loaded with the most current update, if your mb has a replaceable eprom . Its not free, but if you have a high dollar mb, you can save it sometimes:
PC BIOS reprogramming, replacement, recovery

Okay, that sounds good, but how do I update or change the bios if I can't get a post or anything?
