PC making loud fan noise and no display
I got this old PC but its still good and would like to use as a spare PC in my office room. Its an HP Pavilion machine and has a AMD dual-core processor with 2GB ram and 500GB hard drive. 750 Watt PSU and a 1 GB PCI-e x16 Graphics card from ATI. But when I go to turn on the PC, it starts up and has a loud fan humming sound, and has no video. So I took out the video card and tried it, same problem. I inspected the case fans or Processor fans for any dust, but none whatsoever. It baffles me because I haven't used this machine in a while now and its kept in a dust free location in the house, yet it just won't turn on.
Any advice? I know its an old POJ but just to use it as a spare PC for my documents I guess it'll be worth while. Not willing to spend extra hundred $$$ to purchase a cheap machine.
Please help, thanks.
