ECS K7S5A not Picking up amd athlon xp 1900+ correctly

Recently upgraded my CPU from 1100 duron to athlon XP1900+   . Initially it was picked up as an athlon 1200, i upgraded the bios, upgraded my memory from sdram to ddr ram pc2100 133mhz, and in the bios changed the settings from 100/100 to 133/133. That does work and the cpu is picked up correctly by the motherboard, however the boot process never finishes, it stops approximately halfway through, meaning i have to reboot, and change the settings back to 100/100 and that reads my cpu as an athlon 1200.

My system
ECS K7S5A motherboard
512mb of DDR pc2100 133 Ram
Win98se
Radeon 9200SE 128mb AGP
120gig hd
60gig hd

I dont understand why my pc wont pick up the cpu as what it is?
thanks for any help

Do you get any error messages and/or beeps when the computer freezes?

Do you know the BIOS version you have now? What core does the new CPU have (e.g. Palomino or Thoroughbred)?

Does it make a difference if you take out 1 stick of RAM (so run it with only 1 stick installed)?

Could it be that your power supply can't supply enough current for the new CPU running at full speed? What's the maximum current on the various rails?

Have a look at items 13 and 14 on this page: http://www.ocworkbench.com/2002/ecs/k7s5aguide/psuFAQ4.htm

ok Bios Version is 30811 taken from ECS website, core is a  palamino core. i only have one stivck of ram in at the moment, (no i havent done a memory test, wasnt sure how to do it or which one to use).

Power supply is a possibilty, i dont know how to test the current on the rails, sorry.

And i have used silicon heat paste....what temp should my cpu be running at?

thanks for the answers

Antons answer was brilliant thank you i will probably be loking to upgrade again soon so no point fiddling around with just a new psu.
Yes, it does freeze at the same point now, just after the AVG has run whilst booting and before it gets to the desktop screen.

Thank you for all the help its much appreciated
