Is my mobo fried???

[Oot]

I have a tyan 1854 and it will not power up. I havent changed the wiring in it, and i tested the PSU on my bro's computer, and it worked fine. But the board will fire up for a split second, then turn back off... which.. isnt normal, i've never had it do this before.. I think its fried, as its been acting up forever, but i dont know what to do to make sure..

Save yourself alot of headache and spring for a new mobo, if its wont boot up now but would before and you haven't changed anything and your psu is good , chances are its fried for whatever reason.
