From my previous post computer will not boot up properly same problem as before. I just bought a new 850 watt power supply and it still shuts down on first boot up as soon as windows tries to load. I am thinking it has to do with my solid state drive. I guess I have to just live with it since it runs fine after second boot up. My 750 watt psu is still good and was not the problem it could be the motherboard or the bios is corrupt. I have a logitech z5500 505 wattspeaker set up and I have replaced all the speakers except the sub woofer with klipsch speakers front speakers Klispch synergy F 30 tower speaker Klispch synergy s 10 surround speakers and synergy c 10 center channel sound is fantastic compared to the little speakers that Originally came with the system.
