I recently bought a Gigabyte GA-970A-DS3 (rev. 1.0) motherboard, running the following config:
8MB 1333 SP Dram
Boot drive Samsung 830 SSD
Secondary 1TB HDD
Geoforce 8400 GE graphics
Nothing really radical, but worked well enough.
Running Win 7 pro, then last week I put win 8 on there.
The problems started when I wanted to move to having three displays.
I upgraded the Geoforce 8400 GS to a Gigabyte GV-r770C-1GD, thinking that Gigabyte VGA and MB would be a perfect match.
Now I just get the dreaded "Loading Operating System..." error
I have updated (and reverting) the BIOS, detached and reattached everything, including putting the old graphics card back...nothing, nothing nothing.
Tried a backup bootdrive drive with Win 7 (my old config) nothing.
Checked the boot drive on another computer...it's fine.
Apart from the fact that this MB might be a dud, anything I'm missing here?
My mistake, I was under the impression you got a new motherboard also... not just a new graphics card.
Another possibility may be your PSU itself, is it possible for you to check the voltages ? Just something to check before declaring the mobo dead
Hi - and thanks for your help - very much appreciated.
So, I have replaced the PSU - I think you may have hit on the problem as the new graphics card has a rating on 450W and my ancient PSU (virtually the only legacy part left from the previous 2 rebuilds) probably should have been replaced before now as it has a 400 rating.
I also should have checked this before installing the new card.
So, I now have put in a 550W unit with more cables than I can ever have things to connect to...
And there is some life back. But I think that it must be a problem with the boot drive. Everything looks right (the file systems) looking at it on another machine, but as this is a laptop I can only check it booting as a USB drive - which fails, but i don't know whether that's the laptop or the drive.
I can load the windows install disc (haven't done a re-install) via the DVD drive and can load Clonezilla (as an example) from DVD boot too, which suggests that the MB is actually OK.
So is there a way to recover the boot operation on this drive or is a re-install the only answer?
There must be a way to get your system to boot... I'm at a blank at the moment. I'm almost suspecting that some neccessary file(s) got corrupted on the HDD - did the system shut down (not restart, actual power off) while loading windows during your first boot attempts with the new GPU?
I think I figured it out, but the reinstall is probably needed anyway...
I figure the old graphics drivers were probably the issue, if they hadn't been wiped before the new card was installed, there was probably a conflict.
Don't know for sure, but that's what I'm figuring.
If you can, replace the old vid card, try booting... wipe the drivers for it then replace the new vid card - if you haven't already reinstalled
