Hello, i was just wondering, with all these wont boot up , no usb power topics, i have a problem of my own i quess, yes it is simial to all the other stuff, there is Just one stange aspect in my problem: I Can get my computer to boot and and have running it for 30 days straight(i quess this is the oddpart, (cant be from ram/electric taking contact somewher it should/psu nor motherboard), cause i think it should be able to run up if there would be problem in these? The thing = only way all most 95% of the time i get the computer booting IS turning the power switch on, pressing the power button on front of the computer, all the fans start to roll and stuff, but it wont boot up, heres the trick i do: Quickly turn the power from PSU off and the back on, like 4secs after, the fans slow down like they should run normaly, and the computer boots up just fine, Just that this allmost feels as a luck when it happens, all the random, tryed unplugging rams, removing GPU and stuff, have changed thermal pastes even from CPU, But if there would be power outtake, the computer should boot up under any circustances? Any Ideas? i can live it with but i quess this is no good for the computers part, and yes, the computer is homebuilt, problem occurd after like half a year of usage, didnt happen Just after i build it up, can anyone help.?
