I bought a hyper212+ in hopes of overclocking my cpu later. I installed it to what seems like correct as this is my first after market heatsink and in the bios all my components look to be recognized, my hdd's cd drives and ram and even the cpu shows a lower temperature in the bios. When booting up everything looks fine its just that windows 7 doesnt load (colored balls dont show at all) and then I get this message where software or hardware might be the problem and error code 0xc000000f. I tried the boot cd thing but that did not work either. My bios is up to date and that is about all the info I can think of right now. Thanks for all you help.
