S2460 Does not power up anymore (2466 swap doable?)

External Since: Jul 20, 2003 Posts: 8

S2460 Tyan Tiger 1.04 (or maybe later bios)
2x1800 MP
431 Enermax (Now 450 Kingwin: a supported power supply)
2x512 registered mem
Audigy
Geforce3
3COM 590c
21960 SCSI
60G IBM HD

ok i had my fair share of problems with the 2460, freezing the
geforce+audigy cards it was using, corrupting hard drives, but i had this
machine stable for nearly a year now, and it has worked pretty well.
But the other day i turned on the soft power and saw lights flast but
then nothing spinned up.

OK, must be that 431 enermax power supply, checked the 20 pin connecter for
burn marks (from the horror storries on cpu) nothing there. Replaced it
with a 450 kingwin with 45 on the +5 and 30 on the +12, and it still
would not power up.

OK, maybe it's the softpower switch gone bad, I reset cmos, and left the
switch connecter open and hard jumpered (and with the switch on the
soft power pins, not sure if it shorts the pins for a switch on or not),
neither config enabled power up, with both power supplies.

OK, i started taking out cards, i took out the Audigy, ethernet, SCSI cards,
and put the switch back on the soft power pins. Powered up (unfortunatley i
didn't have a montior connected to the gf) and it started spinning, and i heard
2 short beeps. Trying to look for the beep codes now, but the manual says any
beeps not recognizable are memory issues. So i Powered down, And tried each
of the 3 sticks i have (i was only using two 512s) in the first slot and
NO power ups. Yeah i'm pretty sure i seated them correctly when replacing.

Now i can't imagine ALL 3 memory sticks going bad at once, two inside computer
and 1 in antistatic bag outside, so i'm guessing this is a mother board issue.

I've emailed tyan support but i am not hopefully for a valid response other than
did you check your memory is ecc, and your power supply is on the list, and
have you tried our faq most problems can be found here, etc...

What i'm thinking on doing, since i can't find where to purchase a 2460, is
get a 2466 and repace it and hopefully all the drivers will work (save the TSM)

Any help is much thanked in advance.
