I have built this computer with the Intel DZ77GAL-70K back in January with Windows 7 64-bit and had no issues up until 2 weeks ago when I re-installed with Windows 8 Pro 64-bit. This was a complete clean install, not an upgrade. Since then about 2-3 times throughout the day I hear the sound of a USB device disconnecting then reconnecting 1-2 seconds later. During this 1-2 seconds I am unable to use my mouse and keyboard. No messages appear on the screen that anything has been disconnected or reconnected, the only indicator is the sound.
I have ran the automatic drive update tool on the Intel Website and everything is up to date. All Windows 8 updates have also been performed. When I installed Windows 8 two weeks ago I updated the bios to the most current version at the time.
Does anyone have any ideas what could be causing this?
Complete system specs are:
OS: Windows 8 Pro 64 bit
Motherboard: Intel DZ77GAL-70K
CPU: Intel i5-3570k
CPU Cooler: Antel H20 920 (I mention this because it does connect to an internal USB port)
Memory: 4x4 gig DDR3 @ 1866 MHZ
Graphics: Gigabyte GTX 770 OC
PSU: Corsair HX750
Optical: Sata blu-ray drive
Boot Drive: 2x 128GB Samsung 840 pro's in RAID 0 (Using on-board Intel RAID)
Storage Drive: 1TB Western Digital Caviar Black
TV Tuner: Hauppauge HVR 2250
Connected USB devices include: Keyboard, Mouse, Wireless Headphones and Magic Jack.
Thanks in advance for any help that can be offered. Please let me know if there is any more information that I can provide.
After a few more searches I found that someone mentioned disabling USB Selective Suspend in the Windows 8 Power Options. I will give this a shot and report if this has any effect.
