Trying to figure this one out, it's really been bugging me.
P8Z77-V LX with a 3570k, stock everything with a CNPS10X cooler.
Symptoms and what I have done so far...
Will boot 100% of the time using onboard video with no issue.
Will boot 100% of the time using an old GTX8800 and the screen connected to it.
Will not boot using a GTX460 or a GTX560. Both have been tested in another working system(the 460 is out of my wifes). When this happens, it is reverting back to the onboard video, if I connect the screen back to the onboard connector it's working properly even with the videocard installed.
Tried to force PCIE on booting in the Bios. I had to reset cmos after to get back into bios since I could not see anything.
Fans do turn on(including video cards) when I power up the system.
What I have done so far...
-disconnected everything but my SSD(HDD< dvd, etc...)
-reset cmos
-cleaned contacts on the video cards while swapping them.
-swapped ram with another known good set from other PCs(corsair, gskiil and mushkin)
-triple checked PSU connections, swapped PCIE power connectors.
-used another known working PSU(again out of my wifes computer)
What's left to do tonight...
-remove battery to "reset" everything
-remove and inspect the motherboard from HAF-922 for anything odd, damaged PCIE connector?(bad luck happens) reset everything up on my desk instead of the case.
-I read someone had to boot to windows and install all drivers before putting a videocard in? First time i've heard or seen this.
-Open up a bottle of whisky
