[SOLVED] [ASUS m2n-sli deluxe] PS failure...now no usb ports working

[pd0019]

hi everyone....found this forum doing a google search for my onboard usb port failures.

anyways, i have a custom rig with the m2n-sli deluxe mobo. i had low voltage at my house according to edison and had power supply failure last week (my system was running just fine before) and so bought a new power supply (OCZ fatal1ty 550w). i install the new PS and clean my rig up and go to start it and no usb ports are working; none of the back ones and neither are my sides ones. i've tried unplugging all my Pnp's and just running my graphics card and mouse/keyboard with no luck; cleared CMOS; and left my computer unplugged for 1-2hrs (all things that i saw to do while searching on the internet). i obviously cant get into my device manager or windows repair because i have no screen.

any suggestions on what to do? thanks

Can you even get into the bios. If you can see if the USB controller is enabled and set to full speed.

removed 3 of the 4 ram sticks and was able to fix the problem.
