hey guys, i recently built a new computer and i sometimes get a code on my motherboard saying "99" and i just have to press the power button to shut it off and try again till code "a2" which means i can go on the computer and use it i dunno what to do Asrock told me to try this "Problem related to PCI-E devices. Please re-install PCI-E devices or try installing them in other slots. If the problem still exists, please remove all PCI-E devices or try using another VGA card." but ive done that and it hasn't worked like i said i sometimes get code "99" and a 50/50 chance i will get it when i boot up if anyone could help that would be greatly appreciated!

i7-4771 cpu
16gb ram
amd radeon hd 7850 graphics card
asrock z87 exstreme4 motherboard
