Question Please help :(

[GamerGuru420]

I recently cleaned and wired up my pc but then it started acting up by randomly shutting off, so i redid the wiring making sure everything was properly connected but it was still acting up by randomly shutting down whenever it was idle (yes i checked the power plan) today i decided to look back over it and see if there was anything wrong but now it wont even post instead just turning on showing rgb and fans spinning but eventually shutting off. Weird thing i noticed if it helps is the power button does a light blinking blue :/

Any help would be appreciative really dont know what else to do was thinking it could be the case because thats the oldest thing in the build,being almost 7 years old, or the PSU but thats only a year and a half old

You might want to see if the system without the discrete GPU has issues powering up.

Have you tried clearing the CMOS?
