The monitor for my Gateway GT5228 suddenly has "no signal" and then goes into standby. This occured after one year of the computer and monitor working perfectly. I tried hooking up a different monitor and video cable to the computer with the same results. I assumed the onboard video card had gone bad so I purchased a Radeon HD 3650 (PCI express) and put it in the PCI slot and connected the monitor to the new video card...same results. How can I get a video signal from my computer?
When I start my computer I do not get a signal to my monitor. Just get a blank screen. I put on a new cable but get the same result. I hooked my monitor up to a different computer and it worked on the other computer. What should I try next?

Re: No Video Signal
Try resetting the bios. On the motherboard there is a battery that looks like a watch battery. Remove the battery, then replace it again. (make sure the computer is unplugged from the wall socket when you do this)

In regards to your issue with your monitor: For a monitor to display "no signal input" there is likely a problem with the monitor making a connection to your input source (yes I know duh). First and easiest thing to fix this is to check your cables going between your computer and monitor, if your computer and monitor start out working and then fail to communicate, there is a good chance that the cable might be coming loose just enough that the connection fails. I might suggest that if you have, as you say another computer, that you try swapping monitors to check where the problem lies.
That more than likely means the video (graphics) card inside the computer is bad. The monitor seems to be ok if it is displaying No Input Signal. Isolate the problem by connecting another monitor to the computer. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it t the computer. If the Borrowed Monitor displays the No Input Signal then your video card inside the computer is bad. If the Borrowed Monitor works and displays your desktop icons, then your original monitor is bad and the video card is ok.
This looks like a bad cable connection. Try using a new cable for the connection between the computer and monitor. If that does not work test you computer on another monitor to make sure you are getting signal output from the video card.Also check the monitor on another computer.This is to check and make sure the monitor is working properly.You can also try using a add on video card in the computer to see if you can use the monitor this way.If you still are having problems.

Boot into safe mode and see if you can either roll back the driver restore the computer to the date right before you downloaded it.
the link is for directions on how to boot into safe mode.
Another option , if you have on board graphisc alos is to hook up the monitor to the onboard turn it on in BIOS and change the driver for the card using the onther graphics.
Hopefully, it is just the on board video that has gone bad, and not the motherboard. When you install a video card on a PC, that has on board or integrated video, you will need to access the BIOS screen on start up and disable the on board video. That way the video signal will come from the new video card and not the on board video.
