Hearing 1 long and 3 short beeps after starting PC

[Mohammad A1i]

This happens when I turn on my PC for the first time in the day. After that if I shut it down and turn it back on I hear the single beep like usual. I'm not sure why this is happening as this has started happening out of nowhere. After the 4 beeps the PC starts up normally and I can use it. The motherboard is an ASUS Crosshair VIII Hero Wi-Fi and this is what their site says about this:

4. "One long and three short beeps" from speaker

An anomaly is detected in the graphic card. If the graphic card needs an extra power supply, please ensure the power supply can provide enough wattage.


What should I do?

Try turning the monitor on first, before you boot the PC

I always turn on the monitor first. I've turned this PC on in past before turning on the monitor so I doubt that's the issue but I'll still keep an eye on this. Thanks for your reply

Remove and reseat the graphics card.

My guess is that when it's cold some pin is not making proper connection but once its warm it's OK.
