I put together a system several months ago that experienced a long delay when first booting. I tinkered with the issue without success until a few weeks ago when I decided to do a format and clean install of Windows 7 x64. This solved the problem for a week or so, up until I continued to install software and update drivers. I have spent much of the last few weeks troubleshooting and I believe I've narrowed it down to an issue involving the graphics card, so I'm hoping someone can toss out some possible fixes I haven't come up with yet.
Gigabyte Z97-HD3 Rev. 1.0
Intel Pentium G3258
G.Skill Ripjaws X 8GB (2x4GB) DDR3 1600
XFX Radeon HD 6670
Thermaltake TR2 430W
Samsung optical drive
2 WD SATA drives
After I reinstalled Win7, the OS would load within 15 seconds of pushing the power button. But, then the delay reappeared and it's anywhere from 30-80 seconds after pushing power to the POST screen, which only appears for a few seconds before Windows loads normally. When I pull the graphics card and run off the integrated graphics, I can't replicate the delay. I have tried tweaking the BIOS with the card installed, although it's possible I overlooked something there. From the amount of research I've done on this, it sure appears that many similar situations of people complaining about boot delays have involved Gigabyte boards.
I would appreciate any insight into what could be happening during that delay before things finally start up. Thanks in advance.
