New mobo install hangs on boot screen

[Lee M.]

Went from an Epox 8KHA+ with 1800 chip to 8RDA3+ with 2700 chip. Runs fine
once it boots up (WinXP home) but sometimes hangs on the BIOS boot screen.
Sometimes the whole screen doesn't even display. When it does, all the
voltages appear ok. Power supply is a new (< 6 months old) Raidmax 400 with
two 12 volt rails. Sisoft Sandra and MBM both report that the 3.3v rail is
only 2.6v. Could that be part of the problem?

Btw, I have built many systems and never had a problem before so I don't
think I did anything wrong (although operator error is always a
possibility.)

Any sugggestions are appreciated.

Have you checked Epox for a newer bios?
You're not overclocking?

I have the latest BIOS (7/29/04) and I am not overclocking.

If the 2.6 is accurate it's a very real problem. Check it with a 3.5
digit VOM. Spec is 5% 2.97 to 3.63.

I've got a 9NDA3i that is six months old and used to hang every couple three
weeks or so. Bothered me at first, but it seems to happen less as time goes
on, so I'm not all that concerned with it.

I checked the output at the 4 pin connector of the 20+4 main power supply
connector and it read 3.33v so I guess MBM is reading at the wrong location.
The 12v and 5v outputs were also close to nominal.

If it was every 3 weeks it wouldn't bother me but it's more like every 2nd
or 3rd boot.

 

[Lee M.]

Yes, and all the voltages look good on the BIOS screen. The 3.3v rail read
3.33v on the unused 4-pin PSU connector. I'll check out those links.
Thanks.
