Question about Gateway 500 X PC Desktop

Monitor goes into power saver mode

I have a Gateway 500x computer that just started turning off the monitor. When I turn the computer and start it I get the 1st gateway screen with the bios prompt but it has red and blue lines running top to bottom. The next screen that appears is the windows xp screen with the same lines then it goes black and the next screen should be the welcome screen and asks for your user account but mine just turns black and I get a monitor message that my monitor is going into power saver mode just like it lost signal. I can restart the computer in safe mode no problem. I downloaded an updated bios but when I try to install it I get a message that says "Severe,This program is unable to continue. Internal System error: There is a programming or internal problem." I also downloaded an updated video driver which didn't help. I ran PC Doctor on all the hardware and the only thing that failed was the video card memory. Will replacing my video card fix the problem? Gateway suggested that's where to start. I have a NVIDIA GeForce4 Ti4200 128-MB AGP Graphics Card, do I have to buy a card from Gateway or can I go to Bestbuy and purchase one? Any help is appreciated!

    I have tried removing the card and checking the contacts and reseating but still same problem. I'll bring an extra monitor home from work tomorrow and check it but I don't have the lines in safe mode so I didn't think that would be my problem. Thanks! I'll keep you posted.

    Thanks for the help. I tried a different monitor and still had the same problem. Yesterday I bought a new video card and larger power supply and everything seems to be working now.

    I installed a evga gtx 760 graphics card and on start up I cant use the keyboard and my system will not boot...I already downloaded a current bios but still no luck...down on my luck with cheap motherboards from gateway.

  • Anonymous Mar 30, 2014

    When I turn my computer on the monitor displays "no signal". I replaced the motherboard and the power supply. Now I have "no signal" on my computer. What else could be wrong. I've tried troubleshooting but there are no beeping errors. (removed RAM cards, video card, etc. but nothing) What else could I do?

Take your Agp card with you to the shop. You do not need to go through Gateway, but there are serveal formats of AGP regarding the voltages.

By the sounds of it you have the newer version of AGP so finding a replacement card won't be a problem. The only real issue you have is AGP cards cost a lot more then their PCI-e conterparts.

Going from a GeForce 4, look for something like an FX5700 or even a 6200. Don't let the sales guys get in your ear either. Putting any higher video card then these in your current system and your wasting your money.

    Under safe mode your computer does not load the video drivers so the card is not being pushed at all. Under default no driver settings, it's barely out of first gear.

Hi justmee

This actually sounds like a monitor that is going south. However, it could also be the video adapter.

The quickest way to determine which is the culprit is to connect a different monitor to the computer - preferably one using the same video adapter (if you have more than one on the computer.)

If the issues w/ the lines persist w/ a **known good** monitor on the same video connection, then we're not looking at a monitor problem, rather (likely) a video adapter issue.

In that even, the 1st thing to do is to "reseat" the video adapter card. By "reseat" I mean unplug and plug back in. Sometimes the contacts can become corroded or the card wiggled out of place a bit.

(A) Make sure that BEFORE you do this, you remove power from the computer.

(B) BEFORE touching the video adapter, touch the flat of you palm against the back of the computer (an all metal surface area that is an integral part of the case). Do this for a few seconds. This will bring your body's electrical "potential" to the same level as the case. (This is to protect the computer from ESD (electro static discharge) from your body to its sensitive electronic components)

(C) Now, remove the video adapter by touching only the outer edges of the board and NONE of the electronic components or circuitry.

(D) Now, plug the board back in using the same precautions.

(E) Re-connect the video cable from the monitor.

(F) Restore power to the computer and fire it up. See if you still have a problem. (I suspect you will - still it doesn't hurt to try.)

(G) If the problem is still there, replace the video adapter.

When you see anomalies on the screen like you're describing, we're usually looking at a hardware issue rather than a software (drivers) or firmware (BIOS) issue.

In any event, the hardware is where to begin. In this case, we need to know if the problem stops at the monitor or if we need to look in the video adapter direction.

Please, post back here w/ the results of your tests and your observations and questions, etc. We'll work on this w/ you until the issue is resolved or diagnosed.

Thank you

    That's a good observation re: no lines in safe mode. However, when you said you got the lines at the BIOS "prompt", I took that to mean it was during POST (power on self test) at which point, as Mark said, the video adapter hasn't even really kicked in yet at that stage. That's why I was thinking you should check the monitor 1st.

    However, if it's during the Gateway splash screen that you're getting the lines, then that might change things changes things a bit. It could well be the video adapter.

    If you've reseated the card and it worked fine b4, then, if the issue isn't the monitor, we're definitely down to replacing the video adapter.

    Please, let us know how it goes w/ the video monitor, etc. and, of course, if you have more questions or observations, etc.

I have a dell studio 540 desktop, I need to restore to factory settings but my monitor will not stay open. It opens for a few seconds then immediately goes into power saver mode and turns off, how can

I see two things here, but need clarification;

1) Monitor goes to Power Saver Mode, then turns -> OFF?

Sure that monitor didn't go into Standby Mode?

2) Why are you performing a restore back to factory settings?
Pick up a virus?

The monitor receives a signal. A video signal. The video signal comes from the computer.

If the monitor is NOT receiving a video signal, then the monitor will state No Signal.
This is for older monitors.

New monitors do not state No Signal anymore.
It's Power Saver Mode, or Sleep Mode.

If the monitor is truly OFF, the Power On button will Not be lit up.
Or the Power On LED light on the monitor.

Monitor power on LED is lit, or Power On button is lit?

Monitor is not receiving a video signal;

Use a monitor cable from a KNOWN to be working monitor, for a temporary test.
Use a Known to be working monitor, and it's monitor cable.

Need to find out if monitor cable is good.

Monitor cable checks out good?

Then problem is computer.

The two leading issues with desktop computer failure, is;

1) Computer is dirty inside
2) Power Supply inside computer is bad.

How do we turn off the POWER SAVING MODE on the monitor screen?

Try going into your Start Menu then going into your control panel...then clicking on your "power options"....then switching the options to 'always on'..if this does not work..(as it seems you may not be seeing this because the monitor is in power saving mode) try fiddling with the setup option on your monitor and find a possible powersaving mode enabled function and disable it. every monitor is different so I couldn't really help you here...if this doesn't yield results try another monitor to see if it's the monitor having the problems or the computers video card...the video card could very well be the culprit...

When turn on the gateway screen apear, but the monitor turn off or black and not apear nothing my computer is gateway profile 4 all in one

Your power settings may need to be changed, it appears to be going into sleep mode or power saving mode.

If you are using Vista, Click Start> Control Panel > Power Options > "choose when to turn off display" (in the left hand pane) and check that it says at least 10 minutes. Click apply and then ok.

Alternatively, right click on your desktop, select "personalise" and click on screen saver - then select "change power settings" to bring you to the same thing.

If you have xp, right click on your desktop and select "properties" then "screensaver| > "Power" and change it to turn off the monitor after 10 minutes. Click apply then ok.

If your monitor is going to sleep, either press a key or wiggle the mouse to wake it up.

Delay in Monitor display once the system goes in sleep mode

Instead of sleep mode, tyr hibernate. It is generally faster except the whole computer shuts down. When you power back up, you're exactly where you were. Mine takes about 30 seconds.

My Gateway 500s monitor is stuck in power save mode

Try tapping the F8 key while booting the computer, you will get the start up menu, choose safe mode, when you log on, go to the display settings, that is right click on the desktop, properties, screen saver, advanced and make sure that hibernation is off, along with turn off disks or whatever , probably see turn off monitor after XX minutes, I make ours 15 minutes (150 computers and servers), I don't let the disks turn off. Choose always on also, not home/office. Try this and see if these settings help.
