Computer freezing during games, beeps on restart.

Hi, my power supply blew up on me the other day, so I put in a backup PSU of mine. It is an Antec 500w, and was my previous PSU, and it performed up until I got a better PSU for SLI'd GFX cards. My original PSU was an Antec TruePower Quattro 850w. I am currently waiting for a replacement PSU from Antec.

The trouble is that whenever I am playing any game, the computer ends up freezing entirely. Now this is not a huge worry to me, as I can live without having games to play, but the part that worries me, and the point of this thread, is what happens when I restart from this freeze up. Both drive bays light up as if they are being read by the hard drive, and then the beeper makes one long beep follow three short beeps, like morse code.

Is this something I should be worried about? The computer does start up fine after being completely shut off with the power switch and/or the power button on the front of the case. I thought perhaps it was a problem with the PSU only being able to barely power the computer, but after some research that does not seem to be the case.

My system specs are as follows:

-AMD Athlon 64x 6400+ socket AM2
-Asus M2N SLI-Deluxe Mobo
-4 gigs OCZ SLI ready RAM
-Nvidia 9600 GT Overclocked Edition (Removed one due to backup PSU)
-Soundblaster Extreme Music
-2x SATA Hard Drives
-2x DVD-RW/CD-RW combo drives


Any suggestions as to why the game freeze-ups are happening and what those beeps mean would be much appreciated.

Actually, the manual has nothing on that topic, other than where to place the speaker....

Yes, the freezing does involve repeating audio. I just recently updated my drivers, so I doubt that is the problem. The power supply is what I was focusing on. According to the tool on Antec's website, this 500w Power supply is enough to run this computer. I could be wrong and so could Antec, but the computer runs fine except when playing games and that little beeping thing on restart.

I checked a few websites on beep error codes, and they all seemed to say that the long then three short beep code meant bad RAM. Luckily I my original RAM that I have installed and we'll see if that fixes the problem. If not, I'm completely stumped.

try 1 stick of ram. Try it in another slot. Try a different stick...put that in different slots. Swap out video cards. try that in either slot.. try plugging the key board in a different usb port... all boards have different codes which means different things. I saw 3 different problems with that same code with different bioses. keep trying.

Well, I finally solved the problem! Just took out the current vid card and put in my second 9600gt. Started up fine, no beeps on startup, but on restart it was doing this. Moved my RAM to slots 2 & 4 and reset the CMOS. Runs fine one more! Thanks for the help and tips everyone!
