i was installing a USB 2.0 card in my desktop, installed the drivers, restarted the computer and the time was reset to jan 1st 2000. "that's wierd" i thought and was like, "whatever" and changed it to the right date and time. so then i installed the program/drivers for a video port and it asks me to restart but i chose to do it later so i can update windows at the same time. it gets late by this point so i decide to just turn off my computer. i go to turn it on a few hours later because i couldn't sleep and it did nothing. as in it was like it was unplugged. i messed with the off/on switch and pushed the power and reset buttons a thousand times and i got nothing. i thought it might have been something with the power source, but when the on switch is on there's a light on my motherboard that is on. i've tried starting without the card and still nothing.
