Loud PSU fan. PC shuts down at startup. Need help!

post #1 of 8
Thread Starter 
Like the title says.

This is my brother's computer being used as a dvr for security cam.
He explains that it is loud and turns off after a few seconds after being powered on.

So I tested it. First, only the PSU being powered on with a molex fan connected to it. It turned on but the PSU fan was loud. But when I applied pressure to the rear grill of the PSU, the noise was gone. I guess something is rattling inside...could be the fan, but it didn't shutdown.

Second test, I connected the 4pinATX and the 20pinATX to the mobo. Then turned it on and the screen booted up and after pressing delete to enter BIOS setup it just shut itself down. I powered it back on again, but after 3 seconds it shuts down. I couldn't even get to see the boot screen anymore. Tried once more and same thing it shuts down after 3 seconds.

After 20 mins, I tried to power it once more, saw the bootscreen but when I press Delete to enter BIOS it shuts down. Then after that the 3 second shutdown is back again.

I could easily purchase a new psu from newegg/craigslist/ebay, but I was wondering if there is a fix without me replacing anything?

Here is the system specs:

PSU - Rhycom ATX550D
MOBO - Asus P5PE-VM
CPU - P4 3.06GHz
RAM - Kingston KVR400X64C3A/512MB

I appreciate any helpful comments/advice/suggestions and thank you in advance.

Try removing power and pulling the battery on the mobo to reset the BIOS. Sometimes that can clear up issues. Worth a shot before you go out and buy a PSU.

I tried that, but no go. It was a repeat of my Second Test.

I'll wait a bit for more people to comment or shed some knowledge before I buy a PSU.

btw the noise is always there, but if I hold down the rear grill it quiets down. The noise is back once I let go .

I might be wrong, but it looks to me as the PSU is failing. Its most likely using max peak power and unable to power the system, or something of the sort.

before my PSU blew up on me during an end of the year important project that I didnt save it made a loud screeching sound, And started smelling like burning metal.
Then it blew up and smoke started coming out. Luckily it didnt damage any of the other parts

And you should probably just replace it. Its old, and PSU's usually need replacing after 3-4 years. Especially if there crappy OEM.

As you know any efficient 300 watt+ power supply would do just fine.

a new PSU sounds like an order, a good Antec 430w or so should be more than enough for your system.
