Can someone lend me a brick? I’m a windows 8.1 user. - 8GB Corsair ram - Samsung 840 Evo 250GB SSD - Asus Sabertooth 990FX R2.0 motherboard - Seasonic X-series PSU. Backstory: last night I was gaming over my living room TV. I played through a USB 2.0 Hub connect to a usb extension lead to extend the reach of my peripherals (I game this way most the time). I was using a G600 Logitech gaming mouse & Razer Tartarus keypad when I noticed my main keyboard (wireless Logitech K270) had stopped working. Since I couldn’t escape out of the game, I opted to rest the computer. The Problem: On reboot, I found that only my G600 gaming mouse & Razer keypad worked. Absolutely none of my other peripherals work at all except to access the Bios. Fortunately my G600 mouse still worked in Windows, but I had to log in using the “on screen keyboard” to punch in my password. In Windows I checked my Device Manager to find that all peripherals were recognized but unidentified, all except the G600 mouse & Razer keypad. All other peripherals were recognized as inputs by my computer, but unidentified within Windows 8. I have tried to access the peripherals properties to update & establish the drivers on each of the unidentified peripherals but Windows still won’t identify & establish their functions. Numerous resets & shutdowns have been made. Numerous shifting of dongles around USBs (both 2.0 & 3.0) have been made. For the record I have already tried: - Restarting the computer & switching power on and off, as well as unplugging the power supply. - Checking numerous peripherals on separate computers (Mouse and Keyboard Peripherals are all working perfectly fine on two other computers). - Using both wireless and wired peripherals of different brands. However I have not yet tried PS/2 Plug as I don’t have that kind of keyboard & mouse. - Moving dongles around USB ports to test both USB 2.0 & 3.0. - Accessing Bios (Asus Sabretooth 2.0) to ensure all USBs are enabled. (Clearly the USBs a reading the keyboards as I can hit F2 to access Bios. I have also used F5 in Bios to ‘optimize defaults on reboot’) – still Didn’t work. - Entering Windows to re-establish hardware. - I've tried entering safe mode, but between windows 8.1, the SSD & the UEFI bios - I couldn't be more up the creek regarding that course of action. - Finally; Installing Teamviewer for assistance from a friend - a qualified IT guy. Bad to worse: Despite his experience, my friend was as perplexed as I was. He recommended I take out the SSD and access my information on a different computer. I'm not experienced enough to do this, so I finally decided to cut my losses - I would backup my HDD and reinstall Windows 8 (Damn you, Microsoft). However, windows then denied my G600 mouse too! As well my Tartarus. So no peripherals work now. I am physically locked out of Windows (admittedly, it could be that with all the tooling around we did, we forgot to re-enable the G600 mouse in the device manager before rebooting). Be as it may - I'm locked out. …So, what now? Also, Am I able to upgrade to Windows 10 for free, or can I exchange it for a Windows 7?Anything but Windows 8. Some further Observations: Clearly the issue lies not with the hardware, but with the Microsoft Windows software. Interestingly, while the keyboards don’t work – the ‘sleep’ key on my Dell keyboard does work; causing the computer to enter sleep mode in Windows when pressed. So again, the hardware must at least be recognized by the USB.
