Windows suddenly doesn't detect USB, Ethernet, Sound!

[TatesMan]

Hi,
yesterday night the computer was working fine and I didn't download anything
today morning when I opened the computer I found that it didn't detect any of my USB devices (including the mouse) nor the Ethernet cable nor the sound
I tried to do "sfc /scannow" but still nothing is solved
tried on safe mode but the devices still undetected there
when I tried to use windows repair the devices worked fine but I found that all restore points are gone and the devices stopped working again when I booted windows normaly
Now am scanning the computer for viruses but till mow nothing is detected and u doubt that there is any viruses
does anyone knows why that happened and how can I solve it?

I am on Windows 7 x64

thanks in advance

Wow, that's odd indeed! Do you see them in Device Manager? If not, try and do a search for new hardware. Also, if your familiar with navigating the BIOS, make sure those devices didn't get disabled somehow. You may even want to try unplugging those devices, and adding them back to the system one at a time.

I opened the device manager and
1. All network adapters has yellow triangle
2. Sound -> Realtek high difinition audio has yellow triangle
3. All USB controllers has yellow triangle

should I reinstall the drivers or there is another way to fix those ?

Though I do not think this is the cause of your problem, run a scan of your system using Malwarebytes.

Yes, try to reinstall the drivers with the automatic option (search your computer). Perhaps they will reinstall, and you'll be all set. I have no idea what caused this....yet.

If your system can't find the right drivers, then try and run windows update manually to see if they download once again.

Ok automatic install drivers said I already have the driver installed
reinstalling the drivers didn't fix anything
did maleware bytes scan, and 0 objects are infected
thanks for ur help but is there any other fixes?

And btw I can't connect to Internet since network adapters are disabled

My next step would be to try and uninstall one of the devices [in Device Manager] and then reboot to allow Windows to reinstall the device that way. If that works, then repeat the process with the remaining devices one at a time.

Ok thanks a lot for ur time I managed to fix it
I remembered that I installed a libusb for the iPhone but I guess it was a 32 bit verdin not 64 which made my computer act the way I said after turning it off and on

THANKS A LOT again for ur time and help

Peace...

That's what we're here for. Glad you got it figured out. Enjoy the rest of your SevenForums experience. I'll report this as solved.

 

[TatesMan]

Yeah do that, and thanks again

Can I suggest changing the thread title to " Windows 7 x64 suddenly doesn't detect USB, Ethernet, Sound! - because of 32-bit iPhone libusb" to help future searchers

 

[TatesMan]

That's longer than the title limit lol
