Ive had the problem of my PC crashing few seconds after booting into windows, it usually happends when i start my PC fot the first time in the day, than i force shut down it, reboot it and it works perfectly fine for the rest of the night, sometimes it happends every day, sometimes it would stop for a week than the next week it would crash regulary... Ive tried a lot of things, i certain that its not the following parts : Motherboard, Ram, storage. Those things ive replaced and the problem was still there. From the testing ive done, im sure its not software based, ive done everything in that matter even reinstaling windows several times on a clean system, nothing made it go away. Im positive that its the PSU, i bought it second hand, its the Corsair RM750X (older version), but there isnt anything that can make me 100% sure that it in fact is the PSU, i dont want to buy another one to find out that it wasnt the problem, so today i took it apart to check for bloated capacitors or any signs that something might be wrokng, but nothing, carefully checked every part of the PCB for burn marks, and it was like new, the insides of it basicly look new. Thats why im writing my problem here, did anyone experience simular problems and manage to solve them, does anyone know that this is a for sure symptom of a failing PSU? Ive heard that if the problem is in the PSU and if it goes unsolved it could cause big problems to the system, even shorting of other parts? To be clear the problem is not anoying me it happends once in a day i just reboot and go on, if i knew that nothing bad can happen in the form of damaging other parts i wouldent be that woried.
