My msi k9vgm-v will power up, as in the fans will start spinning, but the LED lights and beeps will not turn on and i have to use the switch in the back to turn it off. Recently i upgraded my CPU from a amd athlon 64 x2 4200 to a 4400 and tried to install a nvidia geforce 9800 gtx graphics card. My power source is working fine. Can anyone tell me whats wrong?

Unless the 4200+ was bad or you got the 4400+ for free, the upgrade was a complete was of money. You could have easily changed the BIOS settings to make the 4200+ run at the same speed (or faster) than the 4400+. Are you sure you installed the HSF correctly? The fact that you're not getting any beeps indicates a problem with the CPU, possibly the board. Try removing all the RAM, then try to bootup...it *should* beep continuously. "My power source is working fine" Maybe, maybe not. Is it capable of handling the requirements of the "9800 gx" graphics card?

First of all, the reason i upgraded is because someone messed with the inside of my computer and unplugged the cpu fan with me knowing and it overheated and didnt work anymore. Secondly, i am waiting to install the graphics card till this weekend when i can get an appropriate power supply. I tried taking out the RAM card and still no beeps or lights or anything only the fans blowing. And HSF? (not that good with )abbreviations

"someone messed with the inside of my computer and unplugged the cpu fan with me knowing and it overheated and didnt work anymore" AMD CPUs (like Intel CPUs) have built-in thermal protection circuitry. It's almost impossible to overheat one to death. If it gets too hot, it will simply shutdown & won't work again until it cools. "i am waiting to install the graphics card till this weekend when i can get an appropriate power supply" Hopefully you know what to look for & choose a good one. Amperage is what's important, especially on the +12v rail. Get a brand name unit & plan on spending at least $50 unless a rebate's involved. For example: http://www.newegg.com/Product/Produ... "I tried taking out the RAM card and still no beeps" Not a good sign. "And HSF?" HSF = heatsink/fan, in other words, the CPU cooler.

Ok. I dont know for sure all that the person who messed with my computer did so yeah. I already know what new power supply im going to buy. But still this isnt helping my situation, not to be mean or anything.

I can't do the troubleshooting for you, I can only give suggestions. If you're not getting beeps when all the RAM's out, either the CPU or board are bad, possibly both. My point about the 1st CPU is that it may not be burned out at all. Is the exact same thing happening with the new CPU? What does that tell you? Either both CPUs are bad or the motherboard is bad...or it could be all 3. Are you 100% sure the 4400+ is good? If you are, the board *may* be the problem but you still can't rule out the power supply...it may have suffered a partial failure. It doesn't take much juice to spin a few fans. Since you say you're getting a new PSU anyway, I'd say that will solve the riddle. If the system boots - solved. If the system doesn't boot (& you're sure the 4600+ is good), the motherboard is bad - solved.
