My Foxconn motherboard M61PMV suddenly stopped booting up. No beeps, no monitor but computer powers up. Before this everything was working fine and the computer was shut down normally. Please help me solve...

Will your system come up in safe mode? Try a shutdown and unplug the tower. Plug the tower back in and see if it will come up in safe mode. If it does, go to "control panel", find "device manager" and right click on it. Find "display adaptors" and click on box at right(has a little + inside), it should drop down your device. right click o it and you sjhould see 'enable" or "disable". If it says enable click on that ad you should be good to go. Make sure your connections between tower and monitor are good.

Delll optiplex 755 desktop - motherboard is dr845 13740. Problem with display. When boot up, no graphics on monitor - same as if monitor not connected. monitor checked ok but pc shows no visuals?

I don't know if you have done anything lately,ie; updates to board, cahnge of cables, etc. but first, try shutting down system, unplug your cable for video, unplug tour tower, plug tower back in and restart. If this doesn't work. You may want to try a system restore back to when you had a picture. Try this and let me know if this worked by adding comment or reply at the end of solution.

Power Supply good,buttons on tower ok, but won't power up !!!!!!

Did you pull the CPU out and see if it will power up with out it you should still see the Bios. That would tell you if it was the chip pull one stick of ram out at a time and check by removing piece one at a time.Make sure you turn off the computers power supply every time you touch something inside the tower but leave the cord plugged in so the static goes to ground.

I cannot boot. I believe unplugged a cable connected to the soft power button. It's a very thin cable located at the bottom of the motherboard.

Yes, you did, that is the power on switch form your PC tower / case to the motherboard.

see these pictures:

reconnect that small cable and you should be good to go,
Of course easier said then done. You might have to unplug some stuff to get that plugged back in.

Just remember to re-plug everything!!

Took cover off my tower and blew out the dust and when I hooked it all back up my monitor said no signal and light on my mouse just flashes

Lets tackle the monitor first: A no signal message indicates one of two things;
  • The video card isn't properly seated; (if the video card is on board skip to next step) just moving the video cable on the monitor to unplug it is enough to unseat the video card. Open the tower again and make sure the card is firmly in place.
  • If the video is onboard, the plug may not be firmly in place. Check the screws that hold the plug in place and see if they are turned as far as they will go; there's a chance the plug is only partially making contact giving you the no signal message
As far as the mouse goes, the only reason the machine won't recognize the mouse would be a faulty connection in the USB port. Assuming no damage was done while blowing the dust out, double check the USB port, maybe even changing ports to see if the mouse comes back. If your machine is anything like mine, space behind the tower can get kinda cramped and just putting it back into place and reconnecting the power cord can pull just enough on the lines to pull a line just enough to disrupt your connection.

Hope this answers your questions. Best of luck.

3 plugs inside the tower came unplugged i just replaced my u8668d motherboard with a new one. I am not sure if i hooked up the little black power button connectors on it correctly. Is there any manual or...

you can download the manual from here

pages 3 and 4 give you a quick overview of the connectors and locations. But there are more detailed diagrams and instructions further on.

Good luck
