Hello,
i just set up my new system with a 4770k + new MB. Some strange things happened then, the boot device led + the vga led stays on. When i pull out the graphic card (hd 7970) and only use the onboard graphic i actually get into the bios . However the boot (with no led staying) crashes at windows logo, i think that is caused by my old drivers so i may have to reinstall windows. But thats not the main point, as soon as i plug in ANY graphic card the boot device led + the vga led stays.
I managed 3-4 times to boot WITH my HD7970, i cant reproduce it, but it was when i switched the pci slots several times and reconnected the power cables and then it gets really strange, when i change nothing, just restart from UEFI i get the 2 leds again and it only works again if i use onboard graphic. Once i could restart 2 or 3 times with graphic card, but then it fails.
Things i tried out:
Using different graphic cards.
Using different slots.
Using a graphic card, which only takes power from MB.
Using only 1 RAM.
Using no graphic card -> works but its still weird, sometimes the boot led stays
Using no boot device, using only hdd, using only ssd, using both.
Using MB without case.
All in all i think its the old PSU, which is on no z87 supported list. However i tried to disable the new energy features. Using a silent pro 700w. The CPU-Temperature is fine. I dont think its the MB, because the rest seems ok to me.
Any tips on that?
PS: Im really frustrated, spend so much money for not working ****
