Today I installed a Samsung SSD 850 EVO and installed Windows 10 on it.
I soon noticed problems with the USB ports on my system. Let me mention I had similar problems in the past with Windows 7 but never so severe as this; and my Windows 7 system was running smoothly before this upgrade to 10, with no USB issues.
Now when I boot into 10, devices are not being recognized in USB ports when I boot the system, or they mysteriously "disappear" soon afterward and I begin to repeatedly receive the message: "USB device not recognized. It has malfunctioned and Windows does not recognize it." I have multiple devices hooked up via USB: hard drives, a sound card, a wireless card, keyboard. Any or all of them either won't work or will stop working after the system boots. I have installed all drivers available for my motherboard (ASUS M5A97 R2), and have also turned off all the power saving settings in Windows 10, for hard drives, USB, etc. None of this has helped.
I began to wonder if this was a problem with my motherboard, because a week ago the on-board audio seemingly died. Now I only hear silence and static if I insert headphones or speakers into any of the jacks. This is why I purchased the external sound card. But I booted up from the old Windows 7 system and USB seems to be operating fine there, so I'm guessing this is something Windows 10 specific.
Another worrying thing: on a restart, while I was trying to troubleshoot the USB problem, my system would not boot up but remained frozen on the Asus splashscreen. Before this I had booted numerous times to the new Windows 10 system on the SSD, without issue. But it just suddenly stopped for no explicable reason. I went into the BIOS and found it was not the primary boot device. So I made it the primary boot device. But the problem persists: the system will not boot to Windows on my SSD now unless I go into the BIOS and manually select the SSD.
Any help you can give me to solve these problems would be much appreciated! Thanks.
*Update: I can now longer boot Windows 10 from the new SSD drive at all. Previously I was able to get in by using the "over-ride" option in the BIOS but now nothing, even if it is set the SSD to first priority. If I disable everything but the SSD the BIOS doesn't recognize a drive there. I get the message: "Reboot and select proper boot device." If I enable my old Windows 7 drive the BIOS takes me to my old "boot manager" screen from which I can access Windows 7.
