After I installed a second hand i5 2500k and a brand new ASRock Z77 Extreme3 motherboard (as upgrade from an FX-6200 on an ASRock 990FX Extreme3), I'm having some problems with my computer. One of my case fans doesn't run anymore, the fans of my CPU watercooler are running at full speed (even though they're set at low speed), but most of all: my computer doesn't get any further than the very first boot screen (the ASRock logo with text in the lower right corner, indicating what buttons to press for instant flash, boot preference, and entering UEFI). After that screen has shown for a few seconds, the screen goes black as if it continues booting, but instead shows the exact same screen again. I am able to enter EUFI as usual and selected my boot drive to boot from. All hardware is detected as normal for as far as I can tell. So here are my questions: -Am I correct to assume the problem is with the motherboard or is there a chance this might've been caused by the processor? -Could this problem be caused because I didn't uninstall the previous motherboard drivers (which were AMD) or is the motherboard just busted on arrival?
