I'm suddenly having a problem with my CyberPower PC (specs below). Previously I haven't had many issues other than one of the fans working intermittently. Today, I was working on the PC when the screen locked up. I went to power on the PC and power went to the unit, then off, then back on, and off, etc., until it seemed to boot. However, I am getting no display on either of my two monitors. I tried reseating everything (power plugs, hard drive connections, graphics card, etc.), unplugging an plugging back in connections, all with no luck. No bulges/burns on the motherboard. Most every time I started up I got the on/off/on/off/on/off/etc. and then it starts. I tried unplugging the graphics card and using the onboard motherboard display (HDMI) and removing one by one the RAM modules but that didn't work either. The graphics card fan is on, as are the other fans.
The only progress I have made is when I removed the CMOS battery and then put it back in again. This stopped the power cycling problem, but I'm still not getting a display on startup.
Everything powers (LEDs, multiple fans, etc.) so I don't think it is the power supply. The video does not work on either the graphics card or the built-in mobo graphics so I'm thinking it isn't the graphics card. Is it likely the motherboard?
