Just recently my computer started randomly freezing up, in game and out, sometimes on the desktop, very random.. then all the sudden the display stopped working, it says "no signal" when I turn the power on. The power button blinks consisitantly, it used to stay a solid color, Does anyone have any idea if this means my video card is broken, how do I tell, any help is apprecieted

Those symptoms may indicate a bad video card. They may also indicate a memory, motherboard, processor, power supply, or power problem. Really, any component problem that hangs POST can be a culprit but problems with hard drives, CD drives etc. don't typically result in catastrophic POST failure. It could also be an overheating problem. First try removing and reseating the video card and memory modules. Then if you have extra components, swap them out individually until the problem component is found. The computer configuration can be reduced to motherboard, memory, video, and power supply to simplify troubleshooting by disconnecting non-essential components.

If you have another computer, the video cards can be swapped for independent verification.

I suspect over heating. Has your graphics card got a fan? Make sure all the fans inside the PC is dust free.
Please don't use water lol

Hope this helps :)
