Why my PC switches off automatically?

My Pc switches off automatically. The technician replaced fan in the CPU unit a few months ago but its still getting switched off. Now the technician is saying that it's a hardware problem and need to replace the hardware inside the CPU. Whether I need to buy a new hardware for Rs 2800. Can any one help me.

My PC is 6 yrs old. OS is Windows XP

  1. how old is the PSU?

    how long does the computer stay running?
  2. That's most likely the Power Supply starting to go bad.
  3. BIOS setup CPU readings:
    System temp = 33 degrees Celsius
    CPU temp = 48 degrees Celsius
    CPU Fan speed = 2708 RPM
    CPU Vcore = 1.37V
    3.3V 3.44V
    5.0V 5.16V
    12.0V 12.09V
    Battery voltage = 3.44V

    Is this the PSU problem.
  4. Everything seems normal in the BIOS. From what I understand 6 years on the same computer with no upgrades or repairs. That's most-likely to be the Power Supply going bad. You need to replace it soon; in some cases it can surge out and fry everything (from what I've read/seen).

    If that's still not the problem then it's the CPU or Motherboard starting to give out. Either way, you can order a pretty cheap Power Supply from Amazon or Newegg. I would recommend a 250W to 300W power supply for a normal; everyday use computer.
