Okay My rig is kinda old, G41-P23 motherborad, xeno quad core e5420 cpu, geforce gt 440 gpu, and I just bought a new HDD an a SSD and a new power supply as well. The thing is 1 month ago my old hdd died and i just left my rig to bite dust, until I buy new HDD. I bought it installed it and a new SSD, tried to boot it, it goes as far as windows 10 logo screen and then it just shuts down. I checked and I saw that the power supply unit's (old one) fan is not working and that some of parts inside are burned. I went to the shop and got a new one installed it and I got the same result. Any ideas what it might be? Any help would be appreciated, my thanks in advance
