hello Kai, welcome
the PC is an ASUS, one of the best brands for sure.
the drivers are at Asus.com from 1995 to now, every day, there.
all you do is go there , click your PC there
and see all drivers for every OS they support.
you said w10, so lets see what it there,
2nd google hit.
asus n76v laptop.

easy no>
then i click top right support
and then click drivers
we see no w10 drivers, so there are non for this model.
why not tell the helper which driver fail first.?
DEVICE manager errors or a device is dead?
are you internet connected? on that PC?, do so.
do you know how to force load w8 drives.
the trick is simple
download those drivers that are dead, now.
lets say. wifi is dead (the hard nut)
first connect a CAT5/6 standard ethernate cable from your router
ports to the PC 8 pin Lan port.
bingo you have internet.
then let plug and play work right for the first time.
if that works and wifi driver wakes up end story
if not force load the W8 wifi driver above.
Version V10.0.0.2632013/10/1239.42 MBytesQualcomm Atheros Wireless Lan Driver and Application
down load this.
then unzip the fail to a folder called wifi or what seems nice
then see lots of fails
then see setup.exe
the right click the exe, and pick properties, then tab compat.
and set compatiblitiy mode to w8
and then run the exe and it force loads, w8 into w10
there is no guarantee this works,
if it fails ask how to find a drive, that Asus does not support
nor MS. PnP servers.
we can do that, but you need to tell me the what is failing
first, then pick one to fix first.
we can do it 1 by 1 and never all at once in this silly text box.
you upgraded with out ASUS permission, that is what you did .
in fact most PCs do not run w10 (old ones)
if chip never had w10 drivers ever, that is a problem.
