- Monitor plug is loose
- Maybe you only think that your computer has started. Hit the NUM LOCK key a few times, then CAPS LOCK key a few times. If you see the lights go on and off, your computer really did boot up. IF NOT, then the computer is really in trouble. In that case, unplug the computer and RESEAT the RAM modules; then try to restart the system.

Good luck and Happy Computing!

Asus crosshair socket am2 motherboard not booting


Sounds like your monitor is bad. Try another monitor because if the video card was bad and the monitor is working you would get a No Signal message on the screen. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays ok, then your original monitor is bad. If the Borrowed monitor does the same as your original monitor and does not display anything, then there is an issue with your video card.

Monitor comes on for 2 seconds then goes blank


Check if the cable connecting your monitor from the video card is properly secure and not loose...
You can also try this... turn off your cpu..remove the cable from your video card.....Open the housing....remove your video card from your motherboard... clean the contact surface of the video card with moisten cloth.... after cleaning...connect the video card to the motherboard...attached the cable to your video card.. close the housing and try to boot again...

I hope that work.. if not my suggestion is you try your video card in other computer, try also the monitor to other computer.. to see which one failed.


Much appreciated if you rate this help.. thanks..

15 inch lcd monitor Benq Model Q5T3 has a blank screen has power but screen just black. Can let it sit for a while and sometimes it will stay on for a few minutes but goes black again Thanks


It could either be a driver issue on your system, or a problem with your video card. Turn off the computer, open the case, remove the video card, re-seat it in the slot securely, close up the system and power it back on. If the problem still happens, update the display adapter driver, if it still happens, try a different video card or monitor. You could even test your monitor by plugging it into a system that you know doesn't have this issue.

My monitor goes blank after a few seconds of turning my computer on. I turn off the monitor & turn it back on again and it only stays on for a few seconds thanks


It basically goes to Power Save Mode. Check for the same error in System Setup screen, if the Monitor goes off in System Setup then you better need a replacement. Else you would need to reseat the Video Card(If any) and the Memory Modules. Please keep posting for any further issues / improvements.

Blank screen after turning computer on


Sounds like onboard video might have gone out. 2 suggestions, if the system is still underwarranty, send in for repair. If not, suggestion would be to open the case, and confirm type of slots AGP, PCI, PCI Express, and purchase a video card on the type to install.

Monitor turns on then shuts off in seconds.


check your video card connections. make sure that your monitor cable is attached firmly in place.Also make sure the video card is fully pushed into the slot on the motherboard. Sometimes because of heat the card can pop out of the slot. Sometime this is just enough to barely work and then stop.

Computer boots fine but the monitor is blank


if the monitor works fine on your laptop, the problem definitely is at the computer, possibly with the video card (if it is using one). it could have loose connection, or parts might have damages. it seems the problem is intermittent so electronic component of the video card could have parts partially damages or leaky components.
if your still using the motherboards built in video out put, try installing a new video card.

Screen displays fine for a second, then goes blank


Dor, BenQ has a 3yr warranty on their monitors. I would contact their tech support and receive an RMA to return it for repair. It will cost you shipping out there but they will ship it back. I has a BenQ FP731 myself and it blew a capacitor inside that allowed the screen to stay on. Fixed it and had it back in 5-7 days. Good luck.

Screens works for 5 mins then goes blank!!!!!


It could also be that the video card is not compatible with this monitor. After the pc boots up, can you get into windows? Does the monitor always go out at a specific time on boot? Say for example; you boot the pc, windows startup splash screen comes on; screen does a quick flash and goes blank. Then it maybe the BIOS setting for the video. Try changing the IRQ setting. You could also try putting the video card in another slot. Do you have the manual for the motherboard? Ray
