What are your system specs and what PSU is that?
I am certain this will be a low quality psu that has 'given up'
It's a COOLER MASTER eXtreme RP-500-PCAR 500W ATX12V V2.01.
The rest of my specs:
-COOLER MASTER RC-690-KKN1-GP Black SECC/ ABS ATX Mid Tower Computer Case
-AMD Athlon 64 X2 5000+ Windsor 2.6GHz Socket AM2 89W Dual-Core Processor Model ADA5000CSBOX
-BIOSTAR TForce TF7025-M2 AM2 NVIDIA GeForce 7025 Micro ATX AMD Motherboard
-Sony Optiarc 18X DVD±R DVD Burner With 12X DVD-RAM Write Black E-IDE / ATAPI Model 7170A-0B
-A-DATA 2GB (2 x 1GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400) Dual Channel Kit Desktop Memory Model
-ASUS EAX1950PRO/HTDP/256M Radeon X1950PRO 256MB
-Seagate Barracuda 7200.10 ST3320620AS (Perpendicular Recording Technology) 320GB 7200 RPM
As you can see I don't have a super high-end computer, but I'm happy with it and I'd like it to go back to being fairly quiet like it used to be.
Oh, another thing this computer does, and I guess I'll give this its own thread, is that when I power it up it takes a few tries. The fans come on for a second and it sounds like it's starting up, then it just goes back off. I usually have to push the power button 2 or 3 times then it starts all the way up. Could this be related to my power supply? I don't mind this as much as the loud fan.
Any input is much appreciated!
