OS: Windows 10 Pro AU x64 from Dreamspark (issues occur with both an AU updated from a recent pre-AU installation, as well as a fresh AU installation)
Age of hardware: Purchased in early Aug, started using in late Aug
RAM: Corsair Vengeance LPX 32GB (4x8GB kit) 3200MHz C16 (using XMP profile)
GPU: EVGA GTX 1080 FTW * 2 SLI
MB: Gigabyte X99 Designare Ex
OS Drive: Samsung 850 EVO 500GB, and an extra Sandisk 960GB for data. No HDDs.
PSU: Seasonic SnowSilent 1050W
Update before the issues:
Update 1: Just realized that I've been mistaking the XHCI hand-off as the XHCI setting, but there's actually an XHCI Mode setting on another page. I've changed XHCI Mode from Auto to Enabled, so far for one hour there has been no BSODs yet. The Sensei Wireless still freezes though, so there's probably still some issue remaining.
Update 2: Just noticed that when I turn on my webcam (while Skyping), all USB devices would be force disconnected after a few seconds. So USB devices are definitely still in trouble.
I've purchased some new hardware over the summer, but only had time in late Aug to actually assemble all parts. When I first got the parts in early Aug, I ran Memtest86 where it didn't fail any test for an overnight run. At the time, Memtest86+ did come up with CPU failures though, something about not being able to start additional threads apart from the first one. But IntelBurnTest doesn't result in problems in Windows, so I ignored that.
Windows 10 AU was installed on Sept 1, my cursor occasionally froze, not moving and not registering clicks at all, until I unplug and replug the Steelseries Sensei Wireless (~2 years old). This problem happened on multiple USB ports, and happened both in wired or wireless mode, with or without Steelseries' software installed.
I did a lot of Googling, and found someone reporting freezing issues with Windows 10 AU, so I got an ISO of a pre-AU Windows 10 for a clean installation. Same issue. Upgraded back to AU through Windows Update. I have to note that the Sensei works perfectly fine on another computer, while a friend's Logitech G502 seemed to work on my PC in a short test. Under immense frustration, I went out and bought a Logitech G900.
Except, after using the G900 for a day, a weird periodic mouse freezing problem started showing up. This doesn't always happen, but when it does, every few seconds the cursor would freeze for a second or two. After the freeze, the cursor teleports to the correct position (which means the PC still receives signal from the mouse during the freeze, but it's not reflected on screen). During the freezes, Windows menu still comes up when I press Win key, so it's just the cursor that freezes, not the entire screen.
The problem intensified over the past week. Sept 5 saw the first DRIVER IRQL NOT LESS OR EQUAL BSOD, BlueScreenView shows USBXHCI.SYS and ntoskrnl.exe as the culprits. XHCI handoff is enabled in BIOS. Disabled USB selective suspend setting to no avail, more crashes came. Over the days, I've been getting DRIVER IRQL NOT LESS OR EQUAL about once or twice a day, and occasionally WHEA UNCORRECTABLE ERROR. None of the WHEA could create a crash dump, the screen just freezes at 0% indefinitely every time.
I used to have a bunch of Gigabyte Apps installed, but I saw a post saying they cause BSODs, so I uninstalled all of them. Didn't help. Tried disabling Thunderbolt, for science, but that didn't for either. Installed, uninstalled, and installed Realtek Drivers, no use. No 3rd party antivirus, only Windows Defender. Went through f3 and f4-beta BIOS on the GA X99 Designare Ex, no dice. I haven't really been gaming, but the PC never BSOD'd during the short and sparse gaming sessions. Usually happens when I'm web browsing (ironically, when looking for solutions to BSODs) or when the PC is completely idle.
Stuck at "collecting data for 60 seconds".
Please let me know if I could provide any more information to assist with diagnosing the problem. I've been sitting here pulling out hair ever since getting the computer built, I've spent many hours Googling but nothing solved the problem. I'm suspecting a motherboard fault right now - I really hope not as this would mean dealing with Gigabyte's customer support and potentially a lot of loops to jump through to get this board RMA'd. I gotta admit I've also been avoiding another Windows reinstallation over the week, as grad school just started and I've been scrambling to get my life together. But I will do another clean Windows 10 AU installation if really need be. Thank you very much for bearing through this long post. I'd really appreciate your help, thank you very much in advance!
