Custom PC Build - for parts or repair.

Selling an as is custom-built PC. It features a Zotac graphics card (GTX 780 amp edition with 3gb) and a Corsair RM750 power supply and at least 24 gb of ddr3 ram. The PC is power cycling (turning on and off immediately when powered on.) So I am unable to get the full specs on the CPU. I just don’t have the time right now to tinker with the parts to see what is the issue. Let me know if you have any questions, I can provide specific images if needed
