No Signal From My Computer To The Monitor

Ok well i have a little problem. my computer will turn on and the fan will work all looks and sounds well no beeps.
i turned on my computer after not being on i for like 3 days and it worked fine for about 10 minutes. then it froze and then i turned it off. I turned it back on and i got a "No Signal" on my TV. i didnt even get a bios screen. i tried a hdmi and the monitor cable but still no signal. i made sure the cables worked by plugging into another computer and they both worked. i read other posts and it told me to unplug everything and still nothing. i had just the motherboard power supply and my CPU plugged in and still no bios. i was hoping if someone copuld help me figure out my problem.
