System not working

[smahanty]

When I press the power button, it flashes only once. No fans are spinning. How to fix it ?

Try this:

Unplug your PC from the mains supply.
Press and hold the PC power button for approx 15 seconds.

Plug your PC back in to mains supply.
Now try the power button again.

Nothing happens sir, same result. It flashes only once and no fans spins.

Probably a faulty PSU then. You'll have to fit a new one and see if that fixes it.

Yup, the PSU is faulty. When I tested the PSU with a pin in the connector, the fan still didn't spin.

425W Psu was not enough for my amd fx 6300, r7 260x d5 gpu, gigabyte ga 970A ds3p mobo. Should I go for corsair vs550 ?
