    HI AND THANKS FOR RESPONDING.

    ABOUT 2 OR 3 TIMES THE PC DID THIS: ALL OF A SUDDEN THE MONITOR WOULD DISPLAY "NO SIGNAL" AND I DID A CTRL ALT DEL 2 TIMES WITH NO RESPONSE FROM THE PC. ALSO I COULD NOT POWER DOWN USING THE FRONT BEZEL PUSHBUTTON, SO I PULLED THE AC PLUG.

    I THEN REMOVED THE PROCESSOR HEAT SINK AND CLEANED OUT THE DUST AND APPLIED SOME HEAT SINK COMPOUND TO THE PROCESSOR.

    AT THIS TIME I ALSO DECIDED TO UP GRADE THE POWER SUPPLY TO A 400 WATT ANTEC UNIT.

    THIS POWER SUPPLY I PURCHASED BRAND NEW AND I KNEW IT WORKED CAUSE I TRIED IT IN AN E MACHINES DESKTOP I HAVE.

    SO, I PUSH THE FRONT BUTTON AND NOTHING HAPPENS.

    THE GREEN LIGHT ON THE MOTHERBOARD IS ON.

    PLEASE HELP. THANKS...TOM

    I have exactly the same problem as"guitartom51" but I did not change the power supply which is the original and that all internal and external LED'S are working including the cooling fans.The quad terminal block,next to the main processor,plug is very discolored on the top portion of the plug (P7) where the two brown feeds are inserted.The two black feeds on the bottom part of the plug are ok.I believe that this is the main disconnect lead (switch) to the power supply via through blue bezel button which activates the computer on/off.My View Sonic A90f+ is working . When I unplug the monitor then replug , a message will come on " Off mode in 5 seconds" It will not even indicate a message if I use the blue bezel button on the computer. Do you think it could be the monitor port on the computer or the softwre is obsolete and needs to be updated or nreinstalled? Please advise. Thank you

    I have the same issue with a gateway 500 gr.
    A continuity test of the power switch shows it makes for a split second and then opens, I don't think this is normal. Does anyone know if the power switch on the bezel is supposed to provide momentary or a maintained contact?? Further my power supply
    fails to provide any 12 VDC power, the 5 vdc is fine, i have no cooling fans running but the on board power light light is on.
    I was going to swap power supplies and jumper out the power switch to see if it works....

Most often there are not any service manuals for computers. If you could further explain your issues, we may be able to walk you through fixing them, or give you insight on what could be the real issue.

    Could you tell me if your videocard is onboard, or if it is a card, and if it is a card do you know if it is PCI, AGP, PCI Express x8?


  • Gary Schellhas Jan 25, 2009

    Tom,

    Unfortunately under these circumstances, and the computer not turning on at all now, we are looking at a bad motherboard. The motherboard can be serviced but at a cost much more above the price of a new one. A new one can be purchased for about $80-$150 where as PCB service to the motherboard could cost $150 to $500 dependant to the issue. A motherboard can be found using the type of RAM and type of processor. A website such as newegg.com would be the best bet to find these products. If you have any other questions about this solution please post.

    Gary

Here is the driver link to the Gateway 500GR that I found.

http://support.gateway.com/us/en/product/default.aspx?partNumber=3724

Note the system I saw on this page was black and the picture for this system is biege. So it looks like Gateway has a version change with this model.

If you still have trouble let me know all the model info off the back of the computer.

I need to know what are my options if i want to upgrade my gateway 500gr. Mamory, video card, power supply? what else can i do?


If your computer is more than 4 years old and you want a faster computer with a high end graphics card for games, RAM and larger hard disk and Windows 7, then I would seriously consider buying a new computer. You don't need to purchase a new monitor (keep your existing one), this will reduce the costs.
An upgraded old computer would not be as good as a new one, when you consider the costs and time involved with replace hardware and installing Windows on a larger hard drive, device drivers and programs etc.

All PSU's have a RED switch on the back make sure it is set to 115V. Connecting the case back to the mobo is described in the manual. If you do not have the manual you can connect with Gatway through online chat at: http://support.gateway.com/support/contact/chat.shtml

DVD Player on Desktop


Have you tried using different players?  One of my favorite players is VLC.  You can google it and download it for free.  It is a bit difficult to figure out at first but it will handle just about any type of video even fragmented.
