Other thoughts.... you can clear your BIOS by turning off the computer, unplugging it, (press the power a few times while it's unplugged to drain leftover charge), then open her up and find the watch battery on the motherboard. Pop it out. Press the power button a few more times, give it 2 minutes, pop it back in.
Lastly, I'd check for overheating... which is really probable considering it doesn't give you the beeps when you boot it up. The fan on top of the processor needs to be firmly seated. If even one of the pegs are loose... air can get between the fan and the processor... drying out the thermal paste... and making it something you could cook an egg on.
Other very helpful way to find out what's wrong... If you're on windows... hold down the windows key on your keyboard, and press R. WINkey+R. Type eventvwr.msc. Expand windows logs, look under system for errors, and application.
Hope it helps.
Btw... if it's your video overheating... you could download MSI Afterburner... an overclocking tool that aside from it's overclocking nonsense, can usually give you a temperature readout. If it doesn't work for you, can just uninstall it.

Lastly, install and run this. Rule out a virus that could just be messing with you:
