Question

Computer Will Not Post - 3 Short Beeps

Jun 26, 2013 1:04PM PDT

So here's the deal: I had to reset my bios because my bios was stuck on an option only enabling 3 out of the 4 cores of my CPU. I pulled the battery, switched the jumper and put the battery back in and such. When I turn on the computer, it makes its regular beep, plus 3 short beeps after. I've read that there's a problem with the RAM, which honestly isn't possible because moments before, the computer was working fine.



I really need help with this as it is urgent. I have a feeling I may have done something wrong with the battery replacement or resetting the BIOS.



Motherboard: M4A89GTD Pro/USB 3.0

CPU: AMD Phenom II x4 Black Edition

RAM: AMD Entertainment Edition 1333MHz DDR3 4GB

I didn't see where you removed the RAM

and tried to reseat it. How many RAM modules do you have and do you know if you need at least one pair in order to start the PC. Depending on how many modules and the MB requirements, you should see if you can test the modules individually to see if one has failed.

As a note, there are no standard beep codes that are valid for all BIOS but RAM or an unseated video card are two common problems associated with what you are seeing.

Check and verify

If the jumper was the CMOS clearing and you pulled the battery, that's really redundant. You only need to do one of them. If the jumper is returned to proper location after such as well. You REALLY NEED to check your bios, what those beep sequence means. Always recheck your work, because sometimes you introduce a problem fiddling inside the PC, unknown to you, thus recheck your work. Don't take anything for granted, just verify it all again. When you updated the bios AND removed the battery you cleared the bios of all setting, it returned to "defaults" so recheck those setting, it maybe wrong for the ram timing, like X-X-X-X values, so see what's present or finding some mismatch.

Make 100% sure of your cpu stock#, it maybe actually a 3-core cpu, as failed 4-core cpus were sold but ID'ed as such. So again, verify unless it was working as 4-core prior to your bios update. In other words, you seem to want 4-core, how did you know before the bios update it wasn't OK or needed an update. Understand, some cpu checkers like CPU-Z, etc. need be the latest version in order to properly check whatever. Thus, use the AMD own cpu checker to verify what you have.
