your problem is you installed win10 on a computer that is not compatible with it. according to dells website, they only have drivers available for win7 and give the following message
Product not tested for Windows 10 upgrade
Dell is not testing or developing Windows 10 drivers for this product. If you choose to upgrade, some features, applications, and connected devices may not work as expected.
My computer is Dell Studio XPS 9100 desktop and the operating system is WIN 10 Home premium.
From the launch of Win 10 till now, what do you think of this O.S.?
I should say that this operating system is still UNSTABLE and have my personal experience to prove that.
After upgrade from Win 7 till now I have to reinstall this O.S. 2 times. After upgrading for around a few months I found that when AFTER installing the new updates from Window Update the whole system would reboot to a "state" similar to "Safe Mode".
When I rechecked the system configuration I found NO check mark in front of "Safe boot" under the Boot options in the System Configuration Window. The system is NOT truly in a "Safe Mode" but in a "state" looked like "Safe Mode". This is very frustrated especially when I have to re-install the whole system again and again. Any technical help or prevention would be much appreciated. Thank you.
