Hi All, I've had this issue ever since I first built my new PC 2 months ago. Below are specs... i7 4790K Haswell 4.0 GHz G.SKILL Ares Series 16GB (2 x 8GB) 240-Pin DDR3 SDRAM DDR3 1866 GIGABYTE GA-Z97X-Gaming 5 LGA 1150 Motherboard Gigabyte Radeon R9 280X GDDR5 3GB (GV-R928XOC-3GD REV2) Seagate Hybrid Drive ST2000DX001 2TB MLC/8GB 64MB Cache Windows 8.1 64bit So like the title says...games are a chop fest from a cold boot. I get about 10-20 FPS. However once I restart Windows, everything plays just fine indefinitely. I bought a new power supply but that doesn't make a difference. I really don't have much software on this PC because its so new and I'm very careful about malware. So I'm thinking... Motherboard - The computer boots differently between a restart and cold boot. When I cold boot, I get options to enter Bios. When I restart, I don't. Maybe a change in Bios settings could address? A bug? I did reflash with latest Mboard bios but it didn't help. Video Card - I'm really leaning towards this. I stupidly bought the card on eBay from a miner and had to reflash the video bios with VBE7 because he undervolted the card. Also when I start playing games from cold boot, I don't hear the Video Card fans kick up like they should. I've tried a few different Radeon Drivers; no effect on problem. I should also note that this FPS issue also comes back when I wake the PC back up from Windows Sleep. Anyway; booting a PC twice everytime I sit down is annoying and if anyone has some advice to address; I'd sincerely appreciate it. Thanks
Did you try a fresh Windows install before thinking it is hardware ? Updated all drivers for chipset etc ? Checked Event Logs ?
No Windows fresh install but this problem has been happening since I first built computer/installed windows. I did update all drivers/bios. I've never checked "event logs" and I wouldn't know what to look for.

I had a similar problem with my older pc... basically If I just cold booted my pc would slowly start to stutter (both audio/video) till the moment where a reboot was necessary. I remember reinstalling windows, change PSU, change GFX but I never was able to identify that problem... always had to cold boot -> restart to have my pc work like it should have.
