If it used to work okay, first try a new DVI cable as it may have a break inside it.

if that makes no difference, try to get hold of a different, known working monitor to test if your monitor itself is faulty (or try your monitor on another computer will also suffice to check if your monitor is faulty).

If both cable and monitor are not to blame, that only leaves the possibility that your graphics card has failed or it may just need reseating by removing it from the slot then firmly pushing it back in.

Remember the usual precautions with static electricity before you touch the graphics card or any other internal component.

✔ Best Answer
And if/when going inside the computer innards - to remove/reseat etc. the graphics card - ensure you remove the power cord too.

On most current computers - even when "switched off" - but with the power cord still in place and active mains in it.. there are still volts running around the motherboard. Sometimes you can be lucky and remove/replace items OK; sometimes not so lucky - when there is still an active mains connection (and thus volts on the motherboard)... So wise to to avoid the risk...?

On olde AT boards - "off" meant "off" - but on ATX boards etc. "off" doesn't necessarily mean "off" - if there is still active mains plugged in...

On laptops one also removes the battery too - for obvious reasons.

Assuming there's a speaker connected to the motherboard & there's no beeps at startup, you have a major malfunction. It could be the board, the CPU, or power supply. If this is a fresh build, it should have been bench tested before any hardware was installed in the case. Have you ever assembled a system before? Are you sure the heatsink was installed properly on the CPU? Correct amount of thermal paste, middle dot method?

Please list your complete specs in detail. Asrock makes a LOT of different boards, there are a lot of 8GB RAM possibilities, & there's a LOT of different 650W PSUs.

"tried not working" doesn't tell us much. For example, did you check the monitor as per para 2 in #1? If so what didn't work, another monitor or yours on another computer?

We don't know how far you went with the other suggestions either.

Always pop back and let us know the outcome - thanks

I know the monitor is working because I tested on a working pc, and everything else is brand new, (haven't test on the bench though) since it is new I assume it should work, but when I turned the power up, everything powerup, but i don't get any error beeps. like you said. I tried more than once taking out everything and cleaned everything more than once.

Looks like I have to sent this to a repair shop.

Hard to say without seeing it but most likely graphics card (or module) failure.

Always pop back and let us know the outcome - thanks

Thank you for trying to help. I figured out it was my new motherboard that is not good..

Mmm that's a pain... Hopefully (for your sake) it's still under guarantee?

How did you conclude it is the motherboard...?

And thank you for posting back - with you findings etc. not everypne does...

if I can pick more than one best answer I would pick more but since there is only one, I just pick one.

Yes, it's still under warranty so no need to worry.
