I have a Gigabyte GA-MA790GPT mobo that I just installed an XFX Radeon HD560 vid card into. My problem is that when I put the computer to sleep the monitor won't wake back up. The reason I am thinking it is something to do with the mobo is that it would wake up fine when I used the onboard graphics. I have searched online for suggestions to this problem but have found no solutions. BTW, I am using Windows 7 64 bit and this seems to be a problem with Win 7. Any ideas would be appreciated!

Try disabling the onboard VGA in the Device Manager, and in the BIOS if possible {I didn't see any way}. Also, change the Init Display First -> PEG -- assuming the HD 560x is in the blue PCIEX16_1 slot as it's supposed to be.

Also, if ACPI Suspend Type -> S3(STR) fails the try the S1(POS) ; Sleep S3 is the 'ideal' setting and often I find GA fail so S1 is a workaround.

OK, I checked in the BIOS and I had the Init Display First set at PCI. I changed it to PEG and now the problem is gone:) !! Not sure why I had it set to PCI, my bad! Thanks for your help!!!!!!

I spoke too soon... put it to sleep for about 20 minutes and came back, the computer woke up but the monitor wouldn't wake up.

Also, I said -> "Try disabling the onboard VGA in the Device Manager"; open the Device Manager, expand [+] Display Adapters, right-click on the non'HD 560x' and select Disable then restart.

The only display listed is the HD 5670

Then your options are limited:

I assume there's no PSU '4 or 6-pin' PCIe connector off the HD 5670, if there is one then connect it.

Otherwise:
1. Update the HD 5670 drivers per your OS {32 or 64-bit} ; Windows has a habit of using the wrong drivers via Windows Update. AMD -> http://sites.amd.com/us/game/downloads/Pages/downloads....
2. Rule-out a conflict run MSCONFIG -> select Diagnostic and restart ; if problem is corrected then the task is to find 'what's the root cause.
3. Run System File Checker -> http://support.microsoft.com/kb/929833
4. BIOS Update; try the Beta. Use the Q-Flash with a FAT32 USB; it shows up as a HDD and don't forget to extract the BIOS file by running the .EXE file.

5. ACPI Suspend Type -> S3(STR) fails ==> S1(POS) ; sucky option.
