My newly built computer is misbehaving. On a cold boot the video, sound and general responsiveness are choppy. However, after an immediate reboot it works fine. I don't wish to be in the situation where I always have to boot the computer twice so I'm seeking guidance on the root cause and how to fix it permanently.

First... The specs:
  1. ASRock 980DE3/U3S3 AM3+ AMD RX881/760G SATA 6Gb/s USB 3.0 ATX AMD Motherboard - BIOS at 1.60
  2. GIGABYTE GV-N75TOC-2GI G-SYNC Support GeForce GTX 750 Ti 2GB 128-Bit GDDR5 PCI Express 3.0 Video Card
  3. Rosewill R519-BK Black ATX Mid Tower Computer Case w/ 500W Power Supply
  4. AMD FX-4300 Vishera Quad-Core 3.8GHz (4.0GHz) Socket AM3+ 95W Desktop Processor FD4300WMHKBOX
  5. G.SKILL 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Dual Channel Kit Desktop Memory Model F3-12800CL9D-4GBNQ
  6. ADATA Premier Pro SP600 ASP600S3-128GM-C 2.5" 128GB SATA III MLC Internal Internal Solid State Drive (SSD)

  1. NS-40D510NA15 (1980x1080) refresh=60Hz
  2. DELL 2007WFP (1680x1050) refresh=60Hz
  3. Dell E156FP (1024x768) refresh=60Hz

The things I've tried but haven't worked:
  • Updated ALL drivers, Nvidia, Windows, ASRock Cd
  • Backed out Nvidia driver
  • Installed USB Wireless N card
  • Turned off Microsoft Bridged WLAN service
  • Set VSync for Nvidia
  • Disabled unneeded Windows settings such as indexing, pre-fetch, etc
  • Disabled antivirus
  • Turned on antivirus
  • Rain dance in living room
  • Rabbits foot

I'm hoping someone here can help.

Thank you!
