I just installed a new CPU, Motherboard, and RAM into my PC yesterday, and the CPU is performing very badly. It's an i7 9700k. Games are running poorly and I'm getting bad benchmarks on it, but the whole rest of the PC is running perfectly. Haven't yet reinstalled my OS, could that be the cause? EDIT: Reinstalled OS, CPU still running like crap. Not sure where to go from here.
