I am on a Gateway 510S with Windows XP. I do have an installed video card (I have had it for some time...I will have to open up and look to see which it is. NVIDIA? Anyway, yesterday this high pitched noise was coming from the computer so I figured it was dusty etc. Cleaned fans with canned air and still got the bad sound. Figured out it was coming directly from the video card and also was kind of chugging. Opened up, cleaned it out, but now not only do I still have the noise, but the keyboard, monitor, and my network USB are all not coming on. I am on another computer to ask for assistance. I know the computer is old, but when I first heard the noise, I could still use the keyboard and see the screen and I figured if necessary I could change the card out, but now I am afraid I can't do anything! It's my kids computer for school work and such and I would love to get it going again, even if I have to buy a new video card.

I would start by removing the graphics card from the PC and use the on-board graphics. You will then be able to see if the noise disappears and secondly if the other faults are rectified.

The noise you have described sounds very much like a failing fan, that could also be the CPU fan.

Ok I was right about the noise being the video card BUT I still get no response from the monitor and no lights on keyboard and no network usb connection. The comp starts up and runs but never sounds like its getting to Windows when it would get to that lower sounding hum...and of course without being able to see anything on the monitor....i dont know if Im right or not. Im very nervous.

Ok, so you are getting absolutely nothing on the monitor?

Check inside the PC to make quite sure you didn't dislodge any of the connectors, pay particular attention to the hard drive.

When you switch on again see if you can hear the hard drive spin up.

Ok I opened up and made sure everything was tight and the monitor came on as well as keyboard and usb network. Thank you for that tip!! The high pitch sound is clearly from video card as it is not happening now that its out. I will try cleaning it very well and very carefully and putting it back. I did get a start message about a memory decrease....? Does that mean I ruined something else or does it have to do with the video card removal? Uggghh.

Anyway, have you ever heard of a video card getting better (ha) from high pitched whining or should I just plan on replacing it? Its prob 6 years old. My son used to play a lot of PC games but since his discovery of XBOX360 this computer is for school and facebook.

Thanks again for your advice. What a relief to see the screen come up.

Well, I did my best to clean up the card fan and put it back. Everything came back on and that high pitch sound happened for about a second and stopped. The whole machine sounds kind of "heavy" but it has for a while. It was that high pitch thing which got me to open up. Any recommendations I can afford to give it a boost so I get some more time out of it?

Thank you again. It was awful to see no screen/keyboard.

Not sure about the "memory decrease" message, check the RAM sticks by pulling them out and reseating.

The noise from the fan simply means the fan is worn out and the bearing has run dry, you could try using a drop or two of very fine machine oil, but better to replace the fan.

Personal Opinion if it works on the built-in video and you say no more gaming? Leave the video card out and use the built-in video.

Since you say

this computer is for school and Facebook.

The built in should be more than good enough.
Save the money you could spend on a video card towards a new computer down the road instead.

I agree with mark1956, The memory size decrease sounds like one of the memory is loose.

Good Luck
Roger

Thank you both for your help and advice. I think I may go back to the original. As mentioned one kid is on xbox and the other is using it for internet/school and will be taking a laptop to college in Aug. I will check on the mem cards inside as well.
