Pc wont turn on Tags: Homebuilt Systems Last response: January 26, 2010 5:53 PM in Systems Share Unworldlyfriend January 26, 2010 4:13:51 PM I just built a new computer. I5 750 P55A-UD3 Nvidia 8800gt Hitatchi 250gb 4gb OCZ 1333 mhz 1.65v IDE Dvd/rw 375W PSU When i press the power button the PSU makes a Noise and all the Fans inside the case are spinning but It wont POST or Show a display. I was thinking that i need a new PSU? Can anyone else help on this situation? Thanks Tristan More about : wont turn MadAdmiral a c 84 B Homebuilt system January 26, 2010 4:21:50 PM You might want to give the exact model for the PSU. Have you tried the suggestions in the "Read Before Posting about Boot Problems" sticky? There's a lot of very easy fixes in there that can be easily forgotten or missed. If you've tried all of that, I would think it's a bad PSU.

Case fans, PSU fan, CPU fan? Do any lights show up on the motherboard? Are there any beep codes?
