Long time since i worked on one of those chassis but if i remember right there both 250k ohm 1/2 Watt carbon in series
but its more common for them to go open circuit if there burned you better check out the rest of the circuit around the LOPT stage

What is the market value of a Gateway 507GR computer?


Neither could I ... this computer is discontinued ... It is unusual that there are none to be found at eBay nor Craig's List, no rfurbs at any of the usual sites. Since you can't find it and I can't find it ... it is difficult to come up with a 'fair market value' for this discontinued product.

Here are the computer specs ... http://support.gateway.com/s/PC/R/4658/4658sp3.shtml

I am not sure how 'mint condition' applies in this case ...

I think you will need to add memory to this machine ... does it come with an OS? Is it running now? Can you check the Microsoft Hardware compatbility list at http://www.microsoft.com/whdc/hcl/default.mspx

Here is an interesting site ... http://www.retrevo.com/search?q=Gateway+507GR&rt=oa&modelid=7784763 On their review section, they say this computer is over the hill ready to retire.


If I were interested in this computer, I would offer $100.00 but not go more than $150.00. I think this is very generous.

I HAVE ONE MOTHER BOARD MS--639O VER:30B AND


HP motherboards are made by a motherboard manufacturer, for HP.

Typically Asus and Foxconn.

These manufacturers are the only ones, that would have direct values given for components used on that motherboard.

For example such as the capacitor's coded c212, and c209. (Code stamped on the motherboard next to the component)

Same thing with resistor's r9, r10, r12, and r13. However, the value should be coded on those resistors, just like any resistor. Use the color bands.

http://www.csgnetwork.com/resistcolcalc.html

A lot of times Electrolytic Capacitors that are of cheap quality, are not marked except for a manufacturer code marking. By the Electrolytic Capacitor manufacturer.

You may, or may not have luck in finding what that manufacturers code is.
First thing you need to find is what manufacturer it is.

Generally, manufacturers use a symbol for their name. Sometimes they stamp their name. Example Sanyo.
From there you can find out the needed information.
I believe the following article may help you in your endeavor,

http://www.hardwaresecrets.com/article/595/2

(The above is Page 2. You may wish to start at the beginning of the article, also.

At the bottom of the written text, you'll see 1, 2, 3, and 4 in blue for the page numbers)

You can also tell me what you see on those capacitors, and I'll try to help identify them, and their values.
Just post this information in a Comment.

I have a Gateway GT5056, no monitor will work.


The video card you have is integrated into the motherboard. You would have to buy a whole new motherboard to fix the problem. It would almost be cheaper to buy a new computer though.

Signal to monitor goes in and out, mostly out


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.

I hope this helps,

Eric

Motherboard for Gateway gt4022 fried. Replacement?


if you want to reuse the processor and Ram from the broken board you'll need to buy a board that they'll be compatable with ....I would suggest going to your local independant PC shop and getting some quotes....also bear in mind that some motherboards come with different ports on the back eg parallel printer port....so make sure the board has what you need

Green light constantly blinking. No image on the monitor. Burnt spot on circuit board by the heat sink. Need schematic to identify resistor to get replacement


Unfortunately, most consumer devices to not have freely available schematics. Plus, the chances of the resistor in question being the only faulty part is low, as something must have caused the resistor to be overpowered.
