Ok, So I currently have a Dell XPS 410, I was playing WoW last night and the game froze, has happened before, usually because i have a bad connection to the internet and i just have to ctrl alt delete and close it out and reboot the game, well last night that didn't solve it so i rebooted my computer and did a complete system restore to an earlier date where i did not have this problem, went to bed... Today i got up and tried to get on for some more gaming but my keyboard and mouse would not work, i rebooted and got them to work in the BIOS/Setup menu but once windows booted it wouldn't work again, i couldn't type in my password to get to my desktop screen. I was using a PS2 Keyboard that did not match up to the PS2 slot on my tower so i had to buy a PS2/USB adapter, but NONE of the USB ports are working, The mouse and keyboard are recieving power from the computer as the mouse's little blue laser lights up and stays on but the only light that will even come on on the keyboard is the num lock button, what is wrong?!?!?! Please someone help me.
