What type of external hard drive can be added


The motherboard can only take 2 GB of memory. If you tried a larger memory stick in any slot, the motherboard will fail to recognize it. A larger hard drive or an external drive will only increase storage and page file capacity. This will not improve the performance of the computer. Memory caching to the hard drive is limited to the bus speed of the hard drive interface (much slower than the RAM).

The better option if you can offered it is a new computer, if you do any gaming. You are dealing with a 2.8 GHz CPU with a 400 MHz bus. The computer is probably fine for e-mail but video and gaming response will not improve.

I wish that I had better news for you.

What is the maximum limit of Processor my OPTIPLEX GX26- can support? i have currently 2.4ghz processor working and i want to now what is the max limit i can upgrade it to, can i place intel core duo?


Sorry, the GX260 can not support a intel core duo. The processor sockets do not match the motherboard.

Also, it can handle any pentium 4 processor that uses an 800MHz bus speed, because the highest bus speed that the GX260 motherboard supports is 533 MHz. The fastest processor available for the GX260 is 2.6 GHz.


Here are the tech specs:

My current data bus speed is 400Mhz I want to upgrade my memory, Can memory of speed 533Mhz work. What changes will I have to make?


It May work but the bus speed is going to stay the same if it is max clcoked at 400 MHZ thats it no faster unless your computer can be jumpered to a higher speed but most you are limited by the clcok speed of the buss.

Video Card question...


It can support the card although the bus speed of the board could limit video thru-put. Another issue to consider is the wattage of the power supply which is at the low end of what is required. I would recommend a 400W minimum.

Compatibility of PCI-EXpress card for Dell GX280 (Small Dextop)


So if this is a slimline pc you are kind of limited in upgrade options
space being the biggest , then being followed with cooling ability, the best advice I can give you if specs say 350 is needed i wouldn't chance having the card pull more of a load off of the PSU than what is rated for it. Hope this helps

Hello, My name is James. I have a problem with my 2050 GB Toshiba External Harddrive(Cypress AT2LP RC42). My copmuter can't reconaise it no longer. Can you guys help me out?


Check the power supply. Re-install the drivers if applicable. Can you hear the hard drive spinning, does a light come on? Also try a different cable from the device to the computer. Go into Device Manager and see if their is some info there. Check the bus that it uses (USB, Firewire, etc) in Device Manager. If you know how, remove the hard drive from the case and install it on a bus inside the computer case. If it works this way you know the problem is with the external case or power supply.

probably that's because of faulty hard disk bus. replace that bus, and your problem will be most probably solved.

USB malfunction


Hello jaybear

The most likely problem is your USB bus is underpowered for supporting your external hard disk drive along with other USB devices.

First, this is actually a good thing in a way. The reason is, it is actually telling you right up front that your USB bus is underpowered for this device. That's a huge improvement over issues caused by underpowered USB buses in the previous model computers. In those, we were left to having to figure out what the problem was when a USB device inexplicably stopped or didn't work.

What is happening is, your new hard disk drive(s) (HDD) are trying to run off of power supplied by your computer's USB "bus" (circuitry). This is OK for USB devices needing low power. But in the case of external hard disks, it's "iffy" whether there'll be enough power on the USB bus to support even one of them, much less two or more. Particularly on laptop computers.
Have no fear. This problem is easily remedied. :)

You need only attach an A/C adapter to each of your external hard disk drives and you should be OK.

If that is not an option, connect a **powered** USB hub to your laptop and plug the external HDDs into the hub instead.

By "powered" I mean a USB hub that comes w/ an A/C adapter. In either case, using a powered USB hub or attaching an A/C adapter to your hard disk drives will remove the external hard disks' power load from your laptop's USB bus and provide sufficient power for the HDDs to run.

You can find USB hubs at Newegg.com and lots of other online high tech stores. I like Newegg because their prices are competitive, their customer service is excellent and there're customer reviews of most of their products there as well.

If you have any more questions, comments, observations - anything at all, just let us know. We're here to help.

Otherwise, PLEASE, take a moment to rate the solution that best addresses your problem. If the solution provides a "fix" for your problem, then a **FIXYA** rating would be very much appreciated. :)

Thank you

PCI Video Card


The Specifications to your system states that you have Intel Extreme Graphics onboard. Below is a link where you can find manuals and drivers for that card.
