Weird problem with Intel 810 Motherboards - Help!

[2336]

Folks, I'm trying to set up a little MicroATX system and just went through three different motherboards. All with either the 810 or 810E chipset, all three are integrated (onboard video, audio, etc). Whenever I try to boot up I get nothing! Blank screen, no beep(s) but you can hear the HDD spinning up, the HDD LED flashes, the power LED is on, CD-ROM activity LED flashes, case fan is running and the fan on the cpu HS is running. In fact one of the MoBos, a Tyan S2054S, even has a power LED on the MoBo and that comes on! Any ideas folks? I hooked the monitor to another computer and it powers up just fine, so I know for sure it's not the monitor.

Are you using a CuMine CPU in a board that doesn't support it?

 

[2336]

The first two that I tried were Gateway pulls - MSI 6312s that support up to 933 FC-PGAs and all Celerons and I had a Celeron 600 mounted in there. The Tyan MoBo supports up to 500Mhz PPGA Celerons and I've got a Celeron 433 in there. The Tyan is the one that I still have mounted in the case.

ok, sounds like you know what you are doing... It there a jumper for onboard video?

Do you know if the MSI/Gateway boards were previoulsy overclocked on? I've used a few MSI 810-based boards (6182D and 6182E) that were kind of funky to overclock on. Went something like this...

Boot at default speed
Enter bios and change FSB
Reboot and watch computer hang before POSTing
Turn computer off
Move the FSB jumper from default to whatever you need it to be (66, 100, or 133. Smaller increments in BIOS)
Finally reboot again at the new speed

Stepping the speed back down is equally a PITA. Maybe your problem is related. Do your MSIs have the diagnostic LEDs?

 

[2336]

RGN, there are no jumpers/dip switches for the onboard video for any of the three. ObiDon, I can't even get into the BIOS to check anything like what you suggested. Also, no diagnostic LEDs. I wish I was working on a 6309!

Are they shorting out on the case?

 

[2336]

If they're shorting out on the case wouldn't they just not power up?

 

[ObiDon]

No FSB jumper at all? When I had mine set "wrong" (going 66 to 100 or 100 to 66) then the MSI 810/E systems I built would look dead would act as you described in your original post. No video, drives spin up and I don't even recall a beep. I think the beep comes sometime after the CPU is properly detected and you get a video display...

 

[2336]

I'll check again for a jumper for FSB or anything else. Just got finished putting washers on every mounting point and nothing. I've even tried clearing the CMOS and trying over - no dice!

Okay gang! Here's an update! Just tried motherboard number 4 and it booted just fine! It too is an integrated motherboard but is based on the VIA ProMedia (TekRam) and I immediately got the bootup BIOS identification and it ID'd the cpu and started counting up the RAM AND I got a very audible single beep! What I'm afraid of now is that the other three motherboards are all dead! Do you guys think it would be worth the effort of plugging in a PCI video card and trying? Or is there something I can do to positively verify that they're DOA? I should have no trouble getting my money back on two of them, the third was an "as-is" buy. Silly me!

 

[2336]

Any input gang?

 

[odog]

got a pci video card lying around? if so try that?


other then that try to boot the board outside of the case, and without using the case switch(just short the jumper with a screwdriver)


try booting the board without a cpu and or without ram, and see if you get any beep codes.(hey anything will help)

Yeah, try PCI Vid cards, and do the ol' process of eliminatino (take everything apart and together again)
