That message normally means that your monitor can't handle the resolution being output by the video card. What display are you using and how are you connecting to it?

When you disconnect the 80Gig drive - do you connect the other drive in its place?

I'm inclined to wonder if/think that your hdmi tv in vga mode doesn't like what your sending it... It doesn't recognise teh default vga o/p from the motherboard...

Connecting the 80Gig back in - it fires up; - does that mean you can enter bios OK from power up - or does it mean the hdmi displays OK from the OS on the 80Gig when you boot through to the desktop etc/??

Have you got another "more conventional monitor" (not an hdmi tv) to test with?

Do you have an HDMI output on your computer? If not you may have to get hold of a proper monitor for a little while. TVs can be very fussy about what resolutions they will display.

Long shots...

What happens when you install the 500Gig drive (blank/unformatted etc. or otherwise); can you get into bios then - using the 19inch display (for simplicity)?

If so... what are the various bios settings then?

I am wondering a little if your default bios settings (for the display at least) have been altered/lost in some way? Typically it is vga at least (days gone by it was ega/cga even); and I think there may even be an option for non/absent?

A post fram a while back (in a Ubuntu forum) found he could only get into bios by removing the graphics card he had installed; and then rebooting - at which point he could access bios settings OK?

Per chance when you can boot into whichever OS on the 80Gig.. can you reset display back to on-board vga - even un-install the drivers for your card (which will do the sam thing) .

That "may" allow you in?

Have to admit I'm not that au-fait with what's amiss here; but looking for ideas at least...

I am leaning towards a bios reset - if you cannot get into the bios withe either the 80 or 500Gig drive installed.

I have had quick look at the manual for your board; particularly bios area of course...

Pages 25 and 26 are to do with the on-board vide settings etc... Might be worth a careful read - particularly near the top of page 26...

I'm wondering which mode you are in of the three?

Incidentally way back (in an old post on the www) someone resolved a similar situation with a bios update.. Not sure I'd go there yet... But perhaps call (and/or email) to the Gigabyte tech support might also be in order - to see what they can suggest?

is the manual

And can you confirm you're running windows 7 not windows 8?

i can not get into the bios no matter what i try i have tried to put my os on the 500gb (win7 ultimate) i have managed to get it to boot from cd rom now (god knows how) and windows starts to load files but when it gets to the hard drive selection its telling me i cannot install windows on this drive when clicking on detail tab it tells me that the hdd controller in the bios is turned off but i cannot get into the bios. i have reset the bios via clr-cmos jumper and still no joy. also my board is only 4mths old

Sounds like time to talk seriously to Gigabyte and request a replacement board - as this one clearly has an issue or two...?

I'd be loathe to entertain a bios update as it may make it worse...

Lean on Giga and tell them the board duff (dodgy/faulty etc...)

Boards fails out of the box; after a short while in use, and so on as I'm sure you know.

I wouldn't waste anymore time with it... A warranty is for such a situation as this?

Thank you for the feedback and update.

Hopefully the new board will last considerably longer than its predecessor...
