When i turn On my PC this thing shows in the monitor. <300 XT BIOS P/N 113-A33437-102


Open the case, loosen the 2 screws holding the black plastic casingon the cooling tower over the CPU. Carefully remove, or tilt back to reveal cooling tower radiator and coil.
If there is a layer of dust built up (like there was on mine); carefully vacuum clean the radiator, cooling tower unit, fan and all other surrounding areas. Clean any residue from tower-to-CPU contact area.
Vacuum entire PC inside and out. Remove, reseat, vacuum video card. Reseat storage drive cables reseat the memory sticks, close it up and plug it back in start computer.

Lg w2343t monitor


try monitor on a different working desktop to see if it works, both on the external and internal video card ports. If screen menu buttons fails to respond, fault is either on menu buttons or you may have a burned out lcd screen, try a different monitor on your desktop pc to check its functionality. Monitor probably needs replacement.( It might not be burned out for you mentioned "no signal" error message appeared on screen, have the screen menu buttons checked)

Power blue light flashing when i turn the computer on


It depends on where the blue light is. Is the blue light on the monitor or on the computer tower? If it is on the monitor the monitor is having problems and needs to be serviced. If it is on the tower it could be an issue with the power supply.

Desktop: Gateway LX6810-01 PC will not power on. When I hit the Power button on the tower, a long continuous BEEP comes on and nothing appears on the monitor. After the BEEP, the On light (on tower)...


Thank you for using FixYa

I would try shutting down the computer in the normal way, and turning off the monitor.
Boot up and turn the monitor back on.
If it still doesn't work, then I would check the cables and power plugs and wall plugs.
Check the mouse and keyboard cable and any other cables plugged into the computer.
The next step requires a seperate monitor or laptop.
Try unplugging the monitor and pluging in another monitor. Most laptops have a common
VGA adaptor jack or even an Svideo jack.
If the other monitor does not work, Then take to a qualified technician for repair.
It could be your power supply in the computer or video controller.

I hope this was useful and please comment if this was helpful to you.

Describe your dell dimension E521 wont boot and Problem my computer turns on but doesn't open it goes to a black screen with little flashing bar in top left corner nothing new was installed but there...


The 123 lights on tower translates as:

Routine system activity subsequent to video initialization.
Watch your monitor for on-screen messages.

Disconnect the video cable from the computer and see if you get floating color bars on display. If not, your monitor is defective.

Black Screen


Look in the back of the Gateway where you currently have the video cable connected. If there are two connectors, (Side by Side) there than disconnect & re-connect to the other. Your display should come up. Don't be fooled. Most Pc's that have no display on their monitor is not a monitor problem but a computer problem.
