Problems Booting with new A7N8X

I need help!
This is my setup:

brand new Asus A7N8X
brand new Kingston DDR333 256 Memory Stick
Athlon T-Bird 1 Gig (yeah I know it's really old)
(1) 80Gig Western Digital Drive
(1) 20Gig Western Digital Drive
Audigy 2 Sound Card
Geforce 4 Ti 4200 64mb
NIC Card (i forgot the brand but it's good)
almost new Power Supply from Antec 430watts

So let me explain about the CPU. I am working on upgrading but couldn't afford it all in one shot. And after reading a guide at this site I decided to get the motherboard first because I would get at least some performance boost out of it till I could get an Athlon XP. So I installed everything and it posted but 2 interesting things happend. First it kept posting at a speed of 750mhz no matter how high I set the cpu multiplier. So then I turned up the CPU External Frequency (the FSB I think) to 133 from 100 and it finally got up to 1000mhz. Then I let it run and when it went to load Windows, it reset. I tried all Safe Modes and the system will just not boot. My friend thinks it's just Windows and that I should just do a clean install. I obviously would love to NOT have to do that so any suggestions would be greatly appreciated.

Thanks!

I'd have to agree that you will probably have to install windows over again to get the proper performance out of your new motherboard.

Also, you can buy an XP 1800 Thoroughbred core from newegg for like 65 dollars. That'd be a good boost till you could save more money for a better processor
