I am having a problem with my somewhat new gateway. Intel Q6600 @ 2.4ghz 4gb RAM 2x 2gb 750gb + 320gb HD's DVD burner drive (stock) and a LG burner Radeon HD4850 512mb vista prem 64 bit I recently was having problems with my drive reading a cd, even though it read dvds and wrote them fine. I went in my old computer and took a hard drive out and my LG drive and put them in my new computer. I formated the drive last night, it worked fine. I forgot to plug the white 4 pin wire from the PSU into the back of the drive. (forget the name of the wire). This was today and it then wouldnt start. The power button seems to has "lost it's click" somehow and I can't click it to power it up. I went inside, checked for lose cables and the usual, and nothing. I unplugged the computer from the wall power (back of PSU) and then i plugged it back in, and with out pressing the power button the computer turned it self on. I didn't press the button. The two lights on the video card lit up, the fans turned on, then the lights flashed again, and the computer shut down. Why would the computer turn on right when I power up the PSU with out pressing the power button on the front of the computer? I get nothing, no bios or anything. The power supply is fairly new, and 500 watt. I tried unplugging the new hard drive and lg dvd burner and got the same problem. I just switched my HD 4850 with my older x1800 xl 256mb and I saw no lights, but the computer still started on it's own and shut down and when I press the button, I get no "click" and it stays off. I'm getting very stressed out and pissed because I am 18, and lost my last job and won't be able to order any parts because I'm broke at the moment unlike when I was working. I spent so much time and money on this computer and do not wan't to end up putting it in the closet and having no computer after spending over $1,600 on it. Please help anybody... I already feel like there is nothing I can do. Edit: I unplugged mostly everything and took out the video card, plugged the wire into the back of the psu and the fans turn on for about 1 1/2 seconds then power down.
