Solved Win7 Aero not working on custom-built PC with new components

February 6, 2015 at 12:38:20
Specs: Windows 7
Hi,
I have a problem with a new build: Motherboard Asrock 980DE3/U3S3, psu Arctic Cooling 550R. Windows 7 Ultimate 7 with the current patch level.

If I power up the system Aero Peek is deactivated. Desktop Manager runs, but now dwm.exe is running. Restarting the Desktop Manager has no effect. If I reboot the machine, all is OK, Aero Peek is running. But if I switch off the computer, I've the same problem. I tried it with 2 different graphic cards (Msi AMD Radeon HD 6670 and Asus GEforce GT 610) always the same. Can anybody help me? I always installed the lates driver versions.

Regards Klaus

@sluc: Battery is OK. Start time and date are always correct.

@Hopperfox: I tried also Microsoft fix it: No result.

@Fingers: I updated BIOS, but I had already the current version, no change

But, as I have said, all features run fine after rebooting. But if I shut down and switch on the PC-> the same problem. I removed now the mainboard and will send it back to the show tomorrow.

Regards
Klaus

Did you install the motherboard drivers too? Your hardware is newer than Windows 7.

I installed all motherboard drivers before the graphic drivers. As I have said, only switching on the computer, the problem exists, after rebooting everything works fine. If I remain in the BIOS mode 20 seconds after power on before booting, all is ok too. So, I think it is only a hardware problem either power supply or motherboard (I believe it is the motherboard because I found several posts with this motherboard and the same problem, but until now, nobody could solve it).

I tried all standard solutions, this one too, but without sucess. I tried all, including regedit and change of virus scanner, nothing helps. I believe, next step is to change psu or motherboard. One of them has a defect.

Ok. I tried now another psu, the same problem.

Therefore:
1. Graphics card is OK, I tried a 2nd one and the problem persists.
2. Windows I reinstalled, always the same problem
3. All drivers updated, the same
4. All the solutions tried which Microsoft offers (including registry edit)
5. Power suppler changed, same problem

I think it is really the mainboard which has a problem, and it is reproducible as often as desired. I will remove it and send it back.

Is the time&date on power up still correct?
The (coin) battery OK?
Anything in your windows settings that reverts back to "default" on power on?

Have you tried the Microsoft "Fix it" tool for it?

http://support.microsoft.com/mats/a...

Could be an icky driver issue, where windows 7 does not like the mainboards driver. It can't hurt to run the fix and see what that does.

To err is human but to really screw things up, you need a computer!

It is a bit of a stretch but you can try updating the BIOS. I recently built a machine which booted fine to the onboard graphics but would not show a display on either the onboard or the graphics card once the new graphics card was plugged in. After trying many things, I decided to ignore that for a moment and since I needed to update the BIOS for full function of the newest CPU, I decided to do that. After the BIOS update to the latest (Z97X-UD3H F4 to F7 BIOS), I tried the graphics card (GTX 750Ti) and it immediately worked. Since I did nothing else different, I have to conclude that the original BIOS or combination of it and that particular CPU (Devil's Canyon 4690K) was preventing it from properly recognizing the graphics card. (I included the hardware info in case someone who needs it stumbles across here.)

You have to be a little bit crazy to keep you from going insane.
