I'm having a difficult time troubleshooting this one. My computer when restarting will not post most of the time. Everything powers up, but no post. HDD light lights up solid for about 30 seconds, then goes off. The only thing that solves the problem is unplugging it for a couple of minutes, only then it will boot up. I'm not overclocking anything. Once up and running, everything works great and stable. Please let me know what other info I can provide to narrow this down. Thanks in advance!
