How does a mobo touch the PCI slots? Lol. Only the PCI cards and graphics cards should be touching them.

I'm like 100% sure the I/O shield is conductive, It's made of steel. I have no multimeter around to test it though.

well it is, so if theres something wrong with the mobo, like the electricity flows through the i/o panel, and the electricity gets onto the shield, it'll go to your case you know, and thus your mobo is grounded,

and mobo's can touch the pci slots, some mobos have an onboard sound card which fits into the first pci slot instead of the i/o shield, so hah, im not wrong. though i meant the grafix card which is hooked to the mobo.

i was going to suggest just that actually. scary:wtf:. so this means that the problem isn't with the standoffs so it might be the i/o sheild, try putting the i/o shield onto the mobo when its outside..

Check your HD connectors and maybe swap the cable. Also check the jumper settings in the back of HD.

:toast:

Thats not a problem i just got that error because i didn't have it plugged in. I get something on the screen outside the case but nothing when the mobo is in the game.

has anyone thought about the gfx card not being slotted in correctly when the mb is installed in the case..

maybe it is not engaging the pci slot enough and therefore not working...

Well.... grounding is so that IF there is electricity flowing throughout the motherboard in an unordinary fashion... it will go straight to ground and prevent any injuries or shock or fires.

Graphics cards and sound cards are supposed to be grounded like that. If there is something wrong with the hardware then it needs to be replaced, not ungrounded.

it tells you when your gfx isnt plugged when it posts.
It tells you to hit any key then it shuts down for you to fix your card.

You have to be installing it wrong.. there's no way a motherboard could work outside of a case just fine.. but not inside of a case.

I'm sure you're grounding something that you're not supposed to be... or shorting something out somehow.

The back of the motherboard is not touching ANY metal?

I had the same kind of issue. The mobo drived me nuts for a month and then I gave up. RMAd it and got a replacement that works fine. Its the internal circuit that is shorting when it is placed in a case.

Any other ideas?

Is it a refurbished board u got as a replacement? Call them and explain. Create RMA and get another one. May be another defective one.


My first mobo (Biostar Tforce S754) overclocked like mad. This replacement (I think is brand new mobo) which is a newer version is a dum ass. Doesn't want to overclock the RAM past 200 FSB from 166. For some reason in CPUZ the ram frequency keeps changing when the processor is in load (memory speed goes down when on load and goes up when not). The first one took all the way to 240FSB.

BIG UPDATE: i just pulled the mobo and everything out of the case i don't get anything on the screen.(from outside the case). I also tried a pci gpu and i still get nothing on the screen. I think i am going to rma the mobo again.
