I was playing on my computer today. When I notice my world of warcraft headset was acting funny. So I thought I would power down and turn it back on. When I did this the green light on my computer started flashing and did not turning on. I started doing what I always do if something go bad. Restart the Bios, but that didn't work. I unpluged my headset (nothing), then vidoe card (nothing). Us a def power supply from another computer, but more green blinking. I check the cords, check my original power box to see if anything blow up, and anything else I could think of to see if my over heated or burn anywhere. NOTHING nothing at all was hot or blow up, or even seemed to be damaged. Just to give more info. I have ATI video card 9600 pro, Creative Sound card, MSI mother board, two stick of ram, Kingwin 450mm power supply, one hard-drive, and CD/DVD drive and etc item for gaming. So if anyone can give me a idea what it maybe before I scrap my computer Tower(because I think it maybe the tower starting wires) I would be most Thankful.

When you turn the computer on are you getting any beeps from the motherboard? When you say flashing.. what exactly do you mean? Is is a consistent blinking or is there a rhythm to it like a code? 1 blink then 4 blinks then pause then starts again.

No sound. The Fan for the power Supply switches in the same time as the blinking light and no. The blinking light is just blinking. On off on off on off over and over again at a fast pace.

One thing you can try is unplugging and replugging in the motherboard main connector. Are there any other lights (led's) lighting on the motherboard itself? Have you tried unplugging anything that you don't need from your usb's like everything except keyboard and mouse.

Yes I have done that. No there isn't a light on the motherboard, but from the tower itself when plugged to it. I've unplugged everything and replugged one at a time to see if that work. No keyboard or mouse plugged

The only other thing I can think of at this time is make sure your memory is seated all the way and make fure the CPU chip in in the socket. Other then that its either the power supply or motherboard from the sounds of it.

I hope it just my power supply, but Thank you. I need to buy a new power supply and see if that it.
