Computer - 3 long post beep
Posted on 2011-02-28
I have a computer with a MSI G31M3-L V2 motherboard. It was working fine until yesterday when I boot up the PC, I get 3 long post beep and then nothing. The monitor is blank with nothing. I tried swapping new working RAM as well as a known working video card with no luck. Normally, from my understanding with 3 long post beep is issue with RAM. Yet, replacing it with a known working memory stick yield no result. Could it be issue with the motherboard? I took out all components, blow dust, and reseat it back with same result. I tried swapping the memory stick from one slot to the other and same thing. Tried clearing CMOS as well with no luck.
I'm out of option other than get a replacement motherboard. However, most stores won't let me return the motherboard if I do find out it's not the motherboard after getting it. Want to figure out what other options to try before going that route.
