Question about Dell OptiPlex GX260 PC Desktop

1 Answer

Computer boots up when plugged in,monitor powers down

I put a graphics card(GeForce FX 5500 256MB/DDR/CRT/TV-OUT/DVI) in my Dell Optiplex GX260 Tower(Pentium 4),and while I was at it,I noticed it only had 1Gig Ram,so I removed the two 512k strips and put two 1Gig strips in.I reassembled the computer and hooked it up,but when I plug the power cable in-the back of the computer,the dag-gone thing just boots up by itself,but it BEEPS when it is doing that(about three times-then stops beeping),and when I turn my monitor on it turns on GREEN(the indicator light)-but after about 5 seconds,instead of the picture coming on the indicator light goes AMBER---like it is powered/powering down,and the screen stays BLACK.The computer sounds like it is grinding away-doing it's thing,also the light in the button that says OPTIPLEX GX260 is GREEN.I repaced the monitor with a known good one,but the reaction is the same! I checked to make sure everything was plugged in good.Also-I tried plugging the computer monitor cable in BOTH places on the back of the computer(1)the old hook-up,and 2)the new plug in-which is part of the GRAPHICS CARD)-same results.The Graphics Card Model is: SP8855DT.I even pushed the buttons on my DVD R/W Drive and the door opens and it lights up-same with the CD R/W Drive.Does anyone have any ideas about this/have the same experience/know the answer?Please Help!THANK YOU one and all!!!

    THANKS A LOT! If I knew more about computers,then I could tell you more.What is FSB?The two 512k RAM strips I removed,I think one was 2700 clock speed,and the other was 3200.I will pop the cover back off to check this and see what speeds they are,but a dude in a computer store sold me them,so I figured he took the model into consideration,since he knew I had a GX260.As far as 1GIG strips not working,how can I tell if they are compatible with the motherboard?I had a free analyzation done online,and the survey/test said to put 2 1Gig strips in.Here is some info I got off of the system before I had problems with this set-up: Pentium 4 CPU 2.40 GHz,Processor Speed: 2.33 GHz. Processor: x86 Family 15 Model 2 Stepping 7 GenuineIntel~2391 Mhz. BIOS Version/Date: Dell Comp Corp A02, 7/25/2002. Also on the start up screen it says: BIOS Revision A02. After saying all of that...would this problem cause the computer to boot-up when it is plugged in though? I know also this from the label on the side of the computer: it was manufactured 10/23/02.THANKS AGAIN!

    THANKS WIZ KID! I have effectively discerned this from listening to the BEEPS,and reading the HINT about BIOS on start-up,and whether or not the computer boots-up: there is this pattern of BEEPS." LONG........LONG LONG LONG........LONG LONG". I'm not sure which system I am using(BIOS),but I think that it is RAM related.I am going to go pop the cover and do some testing...THANK YOU AGAIN!!! I will post the results.I am also going to remove that GRAPHICS card to see if that helps...maybe that's not compatible either.I am also going to go on DELL's Site to see what RAM is compatible.

Hi there.......

it is the memory it has to be matched with the actual fsb of the cpu if its slower then it wont switch on.....

and some dell pc's wont work with 1gb sticks so accertain which ram is compatible with the motherboard

Posted on Feb 24, 2009

  • Richard Ray Feb 25, 2009

    hiya matey.

    the fsb is the speed the cpu runs at usually ther is 3 speeds, 100mhz 133mhz and 200mhz.

    and your ram speeds are as follows.

    pc2700 is actually 166mhz ddr which is double data rate so effectivly its 333mhz and pc3200 is effectivly 400mhz so they are not matched speeds this sometimes will work as the faster memory will slow down to the slower speeds.....

    as for compatible memory u should be able to find them on dells site..

    as for the ram speed it should say on the sticks what speed it is.

    as its a 2.33ghz cpu then i wud say that u wud need ddr 333 or pc2700..

    hope this helps matey....

    if u need anymore help drop us a line...........

Problem installation video card

Hello Virna, i have that exact graphics card and dell GX270 desktop here at home, tho it has been awhile since i removed the Nvidia PCI card for a more favorable AGP card. From what i remember, first check your BIOS (hit F2 on startup) and select integrated devices, scroll down and make sure your default video output is either PCI (if available) or AUTO) exit saving changes. If that yields no result. Plug in a second monitor to your old integrated video output, if you can view windows after bootup from there, then you can install the proper Nvidia display driver for windows Xp (available here: ). After installing, right click on the desktop, select properties, display settings tab, and make sure the Geforce card is the main monitor and the desktop monitor. Click apply, unplug the integrated VGA output, and restart. Hope this helps.

Installing New Graphics Card.How do you disable the onboard GC?

To disable the onboard graphics go into your CMOS settings and in there you should find something that says Graphics choices should be onboard or add on or some other form. It all depends on who made your BIOS. As far as a sound card not sure.

Nvidia fx 5200

The only time that this can happen is if the driver is not installed correctly, as on install you are normally asked if you want to activate support for dual monitors, so if you havent already, uninstall the card driver, restart and install driver again from the cd or from the NVIDIA website. If you have already tried this my apologies.

as your primary pc now has a working graphics card . I would guess your graphics card is fried in all honesty there is really no hope in repairing it especially for the cost of one of those cards, if you are simply using your second pc for non graphic intensive apps then I am sure you could find an ol pci grpahics card down the local dump for next to nothing hope this helps.
