Pc won't power on

HP Recommended
Hp pavilion 590-p0027na
Microsoft Windows 10 (64-bit)


Any help would be greatly appreciated. After updating drivers using iobit driver booster (I now know not a wise decision but has always been good in the past) my pc won't power on. It powers on briefly for about 2 seconds then goes off. If I then try to power again the led flashes &  it makes a clicking noise. If I then try again all it does is flash & click. If I reset the cmos it'll try to power on again then goes off without the clicking noise, but flash again & click if I repress the power. I've tried taking out the ram & it'll beep code to confirm but stay on. It's been working fine until this happened.

Thanks for your time on this matter

First:- Turn off the computer, press and hold the PWR button for 4 seconds.

Then - Leave only keyboard and mouse connected, disconnect all externally connected
devices such as Docking Station, USB storage devices, displays, and printers.
Unplug the AC adapter from the computer.

Next - Press and Hold the Power button for 15 seconds to Hard Reset.

AND/OR - Power on your PC, press Esc (repeatedly), then F2 at the prompt.
Choose System Tests (Fast Test does a 4 minute hardware check).

AND/OR - Windows Logo key + Ctrl + Shift + B
(This key sequence actually restarts you graphics drive(W10 only).)

AND/OR - If you’re using multiple displays, try projecting video to a different monitor.
Press the Windows Logo key + P, select a display, and then press Enter.
