Should I replace my PSU?

What is the make and model? This is not sounding good what you describe. A good working PSU is the backbone of any system.

Give us the rest of your system hardware including make and model of your motherboard, amount of RAM installed, harddrive and video card. This will help us help you if you feel you need it.

 

Hi and thanx for the reply..

Motherboard : ECS 661FX-M7
Memory : 1024 MB DDR RAM
Hard Drive: 80GB 7200rpm UDMA
Video / Graphics Card : Integrated SiS Mirage graphics
DVD Drive: Lite-On SOHW-1633S DVD-RW
Sound Card : Realtek ALC655 audio system.

Ive had this PC for about 4 years (as you can probably tell from the specs). I did have 2 GB memory, but took out one slot after i noticed this PSU fan problem two days ago. The PSU fan problems persisted.

 

Okay, thanks for the information. Did you have someone build it or did you purchase it from a PC manufacturer such as Dell, HP, etc.? If you purchased it please give us the model #.

Now, again, what is the make and model of your PSU? Also, how many watts does it supply?
