My gateway computer power light blinks and moniter says no signal.turn it off held then power button on for 30 seconds.then turned it back on.same as before.

I don't think this has anything to do with the monitor since it is showing "no signal". this is an indication that the monitor is working.
Problem is from the connection between the computer and the monitor or from the computer itself.
Check the VGA cable and make sure it is firmly fixed into the computer and monitor.
Open the computer case, disconnect the keyboard, mouse, and every other thing apart from the VGA cord, then try again.
If there is still no signal, turn computer off again, remove it's power cord, then remove the system Ram, clean it and fix it back in. Then make sure the VGA card is well fixed into the mother board. After that, connect only he VGA cord and try again.
If non of the above seems to work, connect the computer to another monitor, and connect the monitor to another computer in other to confirm which is having a fault so that we can focus on it.
Keep me posted.
Good luck.

HPW1907 monitor goes to sleep and says no input signal. Why? How do we fix this problem?


Your monitor is not getting the input signal from your computer. Check to see if the cable from the monitor to your computer is snug.

Test this monitor on another computer, if possible, to see if your monitor or computer is the problem.

Hope these suggestions help.

The signal light is blink and cant get a signal from the wireless computer. Do i need to reset my router?

First off, the computer gets the signal from the router, not the other way around. Secondly, depending on the amount of walls, thickness of walls, amount of interference, the range on your router may not be far enough to reach your computer. If you used to get a signal and no longer can, unplug everything and plug it back in after a minute, that usually fixes the problem. If there is still no signal, try moving your computer closer to the router, or the router closer to the computer. If it is simply that the router does not have enough range, consider upgrading to a wireless n router.

good luck, let me know if you need more help

Linksys wireless b router

Weak signal problem can be fixed by firmware update however, if the client computer is too far from the router, it can't be helped. What you need is a wireless range expander. What it does is give you another 100% signal or atleast stronger signal to the spot or area where you have a weak or dead signal.

My computer is stating no signal


The monitor of the computer is not getting a signal from the computers video card.

this can be caused by a faulty video card, or just the computer not starting up properly.

instead of replaceing parts I would recommend you take the computer to a professional or someone knowledgeable in computers to get it fixed.

Let me know if you need anything else.
