BleepingComputer.com: Laptop's OS will not load

So I was playing a game when my laptop's screen suddenly went totally blank. I tried to reboot, i was able to start up in Safe Mode with Networking. As soon as Windows was loaded, I started AVG to do a scan, but as soon as it loaded, the screen went into a still scrambled pattern. i hard-booted it down and started it up again, but this time it did nothing. The hard drive light flashed around 3 times, and that as it. the HP sign didn't even show, it's just a blank, lifeless screen. that's how it has been every time i try to boot up, the lappy would turn on but never load anything. I have an idea of what i should do, but i want to hear others' opinions before i make any decisions on how to fix this problem.
