motherboard help

[gt_cmpe]

I have a soyo dragon mobo with an athlon xp 190+ cpu and a 350w psu.
Recently I shut the system down and now when I turn it on you can HEAR everything begin to start up normally but nothing ever happens (no video...) Normally I have to hold insert to bypass the cpu fan speed checking (I have a large-fast fan) now I get no error beeps.
--I know the video card is good (I tried it in another unit)
--I tried starting-up with just video and memory, same result
--When I pull memory out I get the appropriate beeps.
--Clearing the bios yields different results, once it got the bios options and froze, once it gave an ORANGE screen?

Is the mobo/cpu toast? And how can I be sure?
Thanks...

I hope the mobo didn't take a nose dive. If you have different ram then try it or if yours is 2 strips then try them 1 at a time, if your psu is generic it could have given up borrow another one if you can to test at the least these may be cheap fixes if thats all it is or try another hard drive see if it boots hdd's have been known to do this also happened to me once, the hdd rom chip got fried.

I do have an antec 350w psu (forgot to mention that) and the fan I spoke of is a TT Volcano7+, It has worked fine for quite some time now with no power problems. There were 3 large transformers that blew nearby our house recently and I convinced the insurance company it was that that caused the problem SO... I have a new Asus kt333 mobo, XP2200+ cpu and 512mb of PC2700 cas2 coming today and I will see what happens, I guess it will be pretty obvious if it is a psu problem.

Any advice on hooking it up to narrow down the faulty component?? i.e. trying the old cpu in the new mobo??
THANKS!

well, it was the mobo that was damaged. memory and cpu came out ok!!! Heres a tip I thought might come in handy.

COUNT YOUR STANDOFFS AND HOLE LOCATIONS BEFORE INSERTING A NEW MOTHERBOARD! I proceeded (in haste) to take the old mobo out and never checked to see if the hole locations were different, I guess I always figured there were standard ATX locations for them. I was LUCKY and did not damage my new board .... this time!

Most newer motherboards can support the higher amperage. A bx6, on the other hand, is considered old, like my asus p2b-f. But if you're wary, you can always buy a 3-pin to 4-pin adapter.
