Pc won't boot into windows after PSU replacement

[Showall]

So,a week or so ago,my brother's PSU died,it was an chineese unit,it was packed with dust,and it suddenly died,with no signs of life.Anyways,i bought a Be quiet 550w 50plus PSU hoping that it will solve the problem.
The first boot after the replacement it went well,everything worked,it was excellent!But after a couple of days my brother noticed it was booting slower and slower,day after day, until one day it decided not to boot into Windows.
The PC itself work mighty fine,but it won't boot into windows AT ALL.The windows logo startss sshowing up,then it freezes,restartss,and offers me to do a Windows Repair Troubleshoot with no Safe mode. Just normal mode and Win. repair. So if anyone has had the same problem,if you can help me i'd be gratefull

I always recommend people reinstall windows and check if it fixes the problem. If that doesn't fix it, then we can talk further

The trick is it worked before,normally,and the day the pc died with the new PSU i noticed one of the two RAM stick has died. So could it be a bad PSU causing it or perhaps a bad MOBO?

IF two ram sticks also died, you might want to test and make sure the PSU didn't take the motherboard and CPU along with it as well.

Might be that the good ole chineese PSU has killed the mobo/ram,cuz the PC worked fine for a cople of days after the replacement and the decided to slowly die,as mentioned before.

Yeah the Psu probably fried the motherboard and everything else
