So today I was just booting up my desktop like any other day then a few minutes after I booted it up, the computer just shut down and it won't boot back up. Instead, there was the beeping sound when you turn on the computer but with a higher pitch. So i decided to take out the RAM, and my graphics card and put it back in again. No good. But now this time, the computer turns on, there is no beeping sound. The fans will run for a few seconds, the computer stops, then the computer starts up again with the fans running but no booting. Is it a PSU problem or is there some other problem.
Computer won't boot up. But fans and lights are on.

When you say no booting do you mean the screen stays black? Or does it get to the BIOS and then shut down?
The fact that your fans are running means the motherboard is giving the "All Clear" signal to your PSU. That likely means your motherboard (and CPU) is fine.
If it's shutting down again after powering on for a few seconds the likely culprit would be a faulty power supply or faulty RAM or both depending on if your PSU fried your RAM.
If you've got some old sticks RAM lying around, try sticking them in instead of your current RAM (if it's not the RAM, you don't have to do anything special to put your old sticks back in, just do a swap again).
If the RAM seems fine, I'd try testing your power supply. If it's fully modular, unplug if from your computer, bring it down to your local BestBuy or tech store and ask if you could get them to test your PSU with a motherboard 24-pin cable and their power supply tester.
A standard power supply tester looks like:
They're only around $20 and invaluable when it comes to testing a first time build or confirming a dying power supply.

Oh wow. I didn't know there was such a thing! Thanks a lot! I get the feeling its most likely my PSU. So I'll give it a look.
