Question about Gateway FX7026 PC Desktop

1 Answer

First of all, I have a Gateway Model FX7026 desktop computer. My daughter was using it when suddenly the monitor screen becomes black. She tried to turn the computer on again but nothings happen. I open the computer and tried to plug the power cord and turn it on but nothings happen..The computer does not turn on. The following is what I have done and observed: (1)When I plugged the power cord to my computer, the motherboard standby led green turns on even not switching the computer power switch to on. (2)When I switch on the computer, the CPU fan will just rotate once and then stops also the motherboard standby led remains on. The power switch LED in front of my computer does not turn on. In other word, the computer does not turn on (3) I reset everything but the same problem. (4) Tried to remove one memory (Channel B-DIMM0)module, the video card, and other drives. I Just left one memory card and the motherboard with the CPU (with CPU Fan) and the chipsets (North Bridge and South Bridge). The same problem occurs with standby_led on. I even put a new memory(from my other computer) but the same problem. (5) Verified the PSU to be good by shorting the green and black wire of the 20-pin PSU plug. Still, Tried to use another PSU with higher power rating but still the same problem.. What seems to be the problem? Any help would be much appreciated.

    The CPU fan is working good. I swapped it with my other computer and it runs good. At this time I don't know whether the motherboard or the CPU is the main problem. What is the standby_led in the motherboard denotes for? It is always 'ON'.

Gotta ask if it is the same exact Operating System. If it is, then there should be no problem. However, if you have upgraded, it will not work.

Gateway fx7026.....beeps three times on startup then reboots? Reason?


Test your PSU or replace it

One bad lead can cause a computer to continue on a cycle or to shutdown

Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your motherboard to your hard drive make sure they have a secure connection and are not faulty or just replace them there probably old and faulty

hope this helps

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. You can use this web address to get customer from Gateway. http://support.gateway.com/s/PC/R/1013953/1013953nv.shtml. I hope this helps you with your problem.

Black screen after a couple of seconds


The monitor needs to be replaced. I had an LG LCD that did this luckily it was still under warranty. Contact the maker and have your receipt handy. Otherwise buy a new monitor. Monitors tend to be replacement only
