ok just finished a problem with my gpu worked fine restarted it a couple of times and now wont turn on the power light on my pc is on but wont start anything no fans no hdd nothing. my pc had a 13a fuse plug and my screen had 5a now i get those 2 wire mixed up cause they look and fit the same so im not sure whats wrong as i should think the pc would have a higher amperage fuse so please help!!

have you blown the 5 amp fuse? or maybe the psu?
