Beep code and random freezing

I've noticed my computer freezing a lot lately for no apparent reason. Its happened in Firefox when autoscolling with the mousewheel and when viewing full screen video. Running Prime 95 causes the machine to instantly freeze as soon as the test starts up. Memtest and the Windows memory test came back with everything fine. I reset and updated the bios with no luck.

I cannot start up the machine without having to press the reset button but starts up fine after I press it.
When booting up I get 4 beeps then the computer starts up. I don't know how to interpret these beeps so here they are.

Any suggestions would be appreciated.

You should provide the specs of your system.

I think you have a short ciruit issue, there might be a contact between your case and your motherboard. Screws that hold the motherboard might be too tight. Also check that you have connected the Case's wires properly to the motherboard's jumpers (power button, reset, lets, speakers etc).

Best thing to do, is take the board out of the case, and set it up out side it.

Carefully remove all parts from motherboard, leaving only the cpu, the fan. Then unplug all cables connected to the motherboard. Very carefully unscrew motherboard and take it out from the case. Place it on top of a wooden or plastic board. Try installing the components -One-at the time until you find out which is the conflicting one.

(Before you start to touch any electronic boards, dont forget to touch the metal case to remove any static that have build up in your body)

Took it out and running off the integrated graphics. It swiches between a "boop beep beep" and "beep boop beep beep". It then freezes after about 5 minutes with green artefacts on the screen. I will not load windows and am running off a linux flash.

I thought beep codes where when the system could not start up?

Is boop a long beep and beep a short one? What does your manual say about beep codes? Your description seems to indicate a video issue, but it could be caused by memory errors, etc. If the motherboard is under warranty, contact MSI.

There is no beep code in the manual and I'm having a hard time translating the beeps using the beep codes Outlander gave. I would say the boop is just lower pitched than the beep and not really any longer. I'm using the integrated graphics now (as opposed to my 4890) and windows will only last for ~5 minutes. I contacted MSI but havent heard a response, its a holiday.

I get the same beeps using either stick in either slot. With no memory i get three very long beeps, much longer.

It sounds like a motherboard issue, but MSI should be able to determine what the beep codes mean.

Okay, thanks a lot for your help.

I underclocked my ram to 800mhz and windows has been runing fine for the past 30 min and prime95 for 20 minutes. Windows would only ever last ~5minutes and prime95 would freeze either instanly or within 1 minute.

Would this indicate a ram issue? I still have the 3 short beeps of different frequency.

That motherboard might be different, but should have a single beep at startup indicating successful POST. Do you get a single beep when using only one memory module?

I did a one of the 50 restarts I did last night but I couldn't get it to repeat.

I'll go thought them again and see what I come up with.

Make sure that the contacts on the memory and the socket are clean.

Try removing one bank of memory modules at a time.

Try using memory modules from the same manufacturer with the same part number and speed.

Check for a faulty memory module by trying the memory in a known good system.

Trying known good memory in the system.

Check the power supply and check for power fluctuations.

If the steps above do not resolve the problem, the desktop board may be defective. Try a different desktop board.
