Alright so a few days ago I was on the computer and we had a power surge (I have no idea why) and so when I tried to turn on the computer nothing would happen. So I figured it was the power supply after looking into the computer some more. I went and bought the power supply from staples, it's an Antec 25 power supply. Ive checked almost everywhere and I've been checking through the BIOS and looked around. nothing. If I don't go to the BIOS the computer reads on startup," Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key_" I've tried inserting the windows cd and tried repairing the startup but i got an error saying it couldn't for unknown reasons and when i tried the system restore it said i had to pick an OS first. Someone please help this is so confusing and i only got this computer just over a year ago.
