Comp crashed...3 long beeps and shut down upon start up

hey guys...heres the deal

i was playing call of duty, had been playing it for weeks at this problems
all of a sudden the game freezes then crashes
turned the comp off and on..played again...freezed the crashed

this time, i turn the computer on, i get 3 long beeps, each about 15-20 seconds long, then it shuts down

i took out the vid card/hd/everything, each time it gave a diff beep error so after trial and error i concluded it was the ram
i have an asus mother board, and 2 1gig sticks of ram
i moved them around, eventually got the computer to boot up, but it only stays booted for maybe 30 seconds then shuts down
itll start loading windows...everything, then it shuts down

i ordered new ram, 2 2gig sticks, put them in (left both old ones out), and the same thing happens

whats wrong with my computer!!!?

  1. What does your manual say three beeps means? (Download copy says there is a table but . . .)
    What power supply are you using, and how old is it?
  2. Thermaltake toughpower W0103RU 600W ATX12V / EPS12V SLI Certified CrossFire Certified 80 PLUS Certified Active PFC Power Supply - Retail

    bought it in 07 with the rest of the parts

    ive been looking for 3 long beeps, didnt see anything in the manual about that

    it just occurred to me it might be 1 long beep and repeats?
  3. you have to look up in the motherboard manual

    you can look at

    from what i know it can be: motherboard video or memory defect

    good luck
  4. i figured it was memory, but even after i replaced the ram it did the same thing

    is there a way to test if its the motherboard?
  5. Unfortunately, once you get down to the core components (motherboard, CPU, and PSU). the only way to tell is to test by substitution.
  6. for how long your pc stays on before shuts down ? it got this problem before once with mine (after 15~20 mins on working well it just shutted down) and it was not the mems, it was the cpu was getting heat and the coolling system was not working well.
    so i used artic silver 3 between the cpu and cooler and i fixed the problem.
  7. try this: unplug everything inside and leave plugged just the minimum to boot: cpu, mem (just one card if possible) and the onboard video card (if u can set up it in bios). check if the system boots.
    your power supply could get a problem. try also this: unplug everything, leave nothing plugged but just the motherboard. turn it on and smell your PS from behind, where the air comes out. if you get a smell of burnt you wil need to replace your PS.
  8. the pc will stay on for no longer than a minute before it shuts down

    im not certain if its the power supple...the computer boots up, goes through the loading screens, starts loading windows and will get to the login and as im typing in my password it shuts down

    i figured it could be the ram, not having enough to run vista, but it seems that wasnt the problem

    when i start it up i dont smell any burnt stuff and ive tried starting it up countless times

    so im thinking its the cpu or the mother board

    but again, why would 1 of these just stop working because of call of duty? there were no other signs of a problem
  9. Probably has nothing to do with Call of Duty. That was just the time that something broke down.

    Your problem sounds like heat shutdown or a psu problem.

    Could you have disturbed the heat sink? If its the push-pin type, its possible one or more of the pins wasn't fully seated and it has chosen now to come loose. Check it. Check and see if your heat sink fan is spinning properly. If your BIOS shows temps, boot into BIOS setup, let it sit there, watch the temps.

    It's likely one or the other.
