It is a GPU issue -- unplug the system, hold the power button for 30 sec. Then remove and reinstall the video card.
See if it'll power up thereafter.
Is this a new card, or one you've been using for a while?
I got the system in february, I've already tried unplugging and holding the power button and turning on without and progress though( I didn't remove and reinstall card after doing this though) and for an update I booted it up with same results, but the power button turned white after awhile, nothing on screen, no lights on inside computer, and mouse and keyboard didn't light up. I read that it could be updating so I think I'll leave it do this for a while. Is that a good idea or no?
You stated, "pretty sure it is a video card problem", which is why I asked, "Do you have another PCIe x16 video card to test in there?". Meaning, do you have another PCIe x16 video card on hand to test? If not, disconnect the monitor cable from the video card. Open the case. Remove the video card from the motherboard slot, reseat it, reconnect the monitor cable, then retest.
