Tyan MOBO freezes on reboot, But will boot cold.

[ndemge]

Tyan board with 850cpu...

From Off, it will boot up, auto detect HD's and go on as normal.

If you RESET without powering down, it will freeze after the memory check when it begins the IDE autodetect.

Replaced bios battery, no change. Any thoughts?

I had an older one new out of the box with the same responce, not helpful but there it is. BIOS updates did not help. Most likely my last Tyan board.

I think I might have found the problem.... I let it sit for a long time, and it finally got past that screen. Light stayed on CDROM... unplug cdrom and it seems to keep going.
Pleanty of those sitting around.

Glad you found the problem. It's always best to disconnect as much as possible when troubleshoting a motherboard.

I'll tell you something else I run into from time to time with motherboards. Take a look at capacitors on the board. Mainly the row of larger ones near the CPU socket but really any of them. Look at the ends. They should be flat. If you see them bulge on the ends or even worse bulge with stuff leaking out they're bad and so is your motherboard.

FWIW, I've never owned a Tyan board, but I've always heard they were good. I know those and supermicro boards were in the top picks back in the late 90's when folks liked to build their own servers. Both were relatively expensive too iirc.

The only Tyan board I had before was when I was working on a dual cpu gaming system way back when in the day

Dual P2-450... spent a lot o cash on that thing. That was in the life before house/wife/kids when $ didn't matter. Wish I had that cash in my pocket now!
