USB/PS2 Peripheral Problems

[chungmasta]

Greetings, everyone!

This is my first post here so I'll try not to sound too stupid.

I built my computer and everything was going alright. Then all of a sudden my wireless/keyboard mouse combo decided to stop working. When I decided to try to restart the computer, I can access the BIOS using the keyboard, but about 5-10 second after Windows startup, the mouse and keyboard refuse to work. This is true for only the PS2 port.

Currently the PS2 port provides power for the keyboard/mouse transmitter, but the keyboard/mouse only works sporadically. When I try to plug in a USB jump drive while the computer is on, there's a brief flash of power, but then nothing. This is true for all of my USB ports. I tried another wireless keyboard/mouse combo that I knew worked on another computer and that didn't help either.

I would appreciate any and all troubleshooting ideas.

Here is a listing of my parts:

sounds like the power supply is not suppling enough power to the usb/ps2 ports.
could be power supply or mother board problem.

Apevia power supplies aren't known to be good quality.

Might want to llok at getting that changed. Here is a list of good brands: http://forum.pcmech.com/showthread.php?t=131195

In the mean time, I would get a wired keyboard and mouse.
