I unplugged and plugged the PSU cable back in 2 times and the second time it just started working, problem was really weird but good its solved

No mention of the manufacturer and model number of the PSU, just 750W. Ditto your RAM.

Please could you provide more details.

What motherboard are you using?

Hope that a loose power cable was the only problem.
