Using an asus z270h motherboard. The pc worked for about a year with no issues. Today I tried overclocking, and I set the ram and cpu frequency up. Clicked save and reset. Pc turned back on, but worked normally, but suddenly turned off. Dram error light turned on. Did many types of fixes including resetting cmos battery. Now all the error lights turn on in a sequence from cpu, ram, gpu and then boot drive. As soon as it reaches boot drive, the fan slows down. Nothing working. Please help
