The screen froze and wouldn't respond, so I turned the computer off. When I try to turn it back on all the fans spin and the computer appears to be turning on normally but nothing shows up on the screen. It's not a problem with the monitor so it has to be the computer. I turned it on with the case off and noticed that on the back of the video card, which is the ASUS EAH4870 Radeon HD 4870, there are three lights labelled D1603,D601,D602, that flash three times and turn off. I don't know if this is significant but I'm including it just in case. The power supply is the ANTEC Neo HE550 and it is 550 watts.
Steps I've tried:
Removing the CMOS battery for 5 minutes
Reseating the RAM
Reseating the graphics card
Holding the power button for 30 seconds
Is there anything else I can try to get it to turn on?
Help would be greatly appreciated.
