Hi all,

I have a friend who just built a computer whose specs are as follows:
ASUS M4A87TD
AMD Phenom II 980 X4
XFX Radeon HD 6870
RipJaws 1600 MHZ 4x2 GB
OCZ 500W PSU

He successfully installed Windows 7 and Battlefield 3 but turned off the computer for the night and now it will not boot up. It will turn on with fans/lights but there is no display. Also, holding the power button will not turn off the system you have to turn the switch on the PSU off to turn it off (the switch will turn the PC on). There are no beeps when turning the PC on and we tried resetting the CMOS.

Any suggestions?

Thanks all!

If the mobo has onboad video try that.

Could be an issue with the video card...another to swap for it?

No onboard video and no other graphics card to swap it for

Make sure all the cables in the case are still plugged in. Sometimes those pesky vibrations can wiggle them loose if not properly secured. Maybe one of the PCI-E power cables came loose when he was playing BF3. Most plugs make a satisfying *click* when secured.

We have unplugged and replugged in everything except the CPU and fans.

Then it is likely the GPU, as QuietPC suggested, since your Motherboard is not POSTing, which indicates that it is detecting a problem. It could be any critical component really, since there is no way that I know of to tell what the Mobo is freaking out about.

If your monitor is connected via the HDMI cable... sometimes HDMI fails to wake up the monitor. After booting up, try turning off the monitor then turn it back on.

Is your video card under warranty? Anyone you can borrow one from to try to see if that solves the issue? If not is there a local shop you could take it and have them try another video card?

If they determine it's bad, RMA, assuming you bought it from a reputable site like Newegg or Amazon.

Question: Does the PC beep when you start it?

Assuming the answer is no:
We have ruled out the Video Card, so the Motherboard and PSU are the next likely causes. If you can rule out the PSU, RMA the Motherboard, or vice-verse.
