No signal from cpu

Check all conections between the tower and the screen, make sure all are secure, if no joy, unplug the tower and remove the side panel to see if the graphics card is in securely, maybe take the graphics card out and put it back in again to be sure. If you have another monitor or monitor cable try replacing to see if the situation improves.

You will need to download and install the very latest drivers for the printer. You can probably find the latest drivers on the manufacture's site or others. Then after that you will want to turn on printer then connect usb after it is turned on>

they all come with two cables. blue being vga, white being dvi cable. you only need to plug the blue into both ends (computer and into the monitor) and turn on. If it is still not working how many video cards are there on the computer? Do you have it plugged into the right spot and is it tight on both ends?

Sounds like either the power supply unit's fan isnt functioning and the the uniy over heats and the computer then wouldnt boot up (to protect itself) or the processor is overheating. But rather seems like a power supply problem

check the cable who comes from the cpu

Hi, sandjkroll, this kind of problem could be because of ur monitor or even because of the on board display  card on ur motherboard. To check ur monitor, u unplg display cable which goes to ur cpu and the power cable which goes to ur cpu. 
Them connect the power plug to mains, so no cable from the monitor should go to the CPU. Then u swithch on the the poower suply, and on the monitor. I
If ur monitor displays elongated screen still, and shows signal not found,and no display comes that means ur monitor needs to be send for service. and if there are no elongated screen and says no signal found, ur monitors fine, ur motherboad has a problem

Hi

First Check the power cable of ur monitor whether power is coming or not..

Then remove signal cable (which is connect the cpu) and then switch one the power, check whether any msg is coming in screen.(like no signal or no connection) if it comes means u want to check the cpu or else their is problem in ur monitor..

Connect the another monitor with ur cpu.Whether ur cpu is working properly..

Please try connecting monitor to known working CPU and determine if problem is with CPU (Graphics card etc) or monitor.Signal cable can also be a problem.
Please rate solution and provide feedback.

Hello,
Maybe it's because it's not getting a signal from the CPU.
Make sure that CPU is working on another monitor.

Thanks,

Take a look behind the computer. If there is more than one monitor port, try plugging the monitor into the other one. Also, certain monitor cards are notorious for not staying in the slot if you move the plug from the monitor around, or even unscrew it. My best bet is that if you open the case (turn off and pull the power plug first, then touch the frame to release static, you'll see that the back of the card is pulled up a little, exposing the connectors on the bottom. Pull the card all of the way out and reseat it into the slot. If the card was not connected before it should be now. Good luck.
