I recently had a computer crash on my machine that resulted in it powering on with 1 long beep and 3 short beeps. I begin to troubleshoot the hardware and find that the video card's gpu fan is caked with dust. knowing that was not a good sign, i started to clean and inspect the card. turns out that the card overheated and the capacitors started to pop, literally. the tops were all busted open. to varify the problem, i put in a video card from a know working machine in the computer and it booted up no problem. this card has never been overclocked, on for extended periods of time, or over strained with high demanding games/programs. this happened because it was in a closed space and never cleaned out. things to remember from this experience: -asus mobo 1 long 3 short beeps means video card not recognized. -clean out inside of case regularly (i use canned air for my computers) -keep case it well ventilated area i hope this helps anyone running into a similar situation later on.
