Hi.
Yes, 3d carsd will work in your computer, the only thing you have do is check and make sure that the computer can supply the power requirements for the card.
Some of the video cards run off of the system bus, while others require a seperate power lead attached to them, the same way you plug in power to a hard drive.
Both of the major manufacturers ATI, and NVIDIA, both make 3d cards that will work with your system.
The cards are all pci-e , as this is the fastest bandwidth the system provides for expansion cards.

Something else you will want to look at when upgrading, is what operating system you will be running it on.
Some of the lower prices video cards, even though they might support 3d, they may not support directx 11.
This is crucial if you are running Windows 7, because that is the version that 7 runs on.
Vista runs on dx 10, and xp and below can only run up to directx 9.

Just keep this in mind while shopping.
Both Best Buy, and Fry's carry large selections of 3d capable cards, just remember about the power requirements before you buy.

I hope this answers your question, and gives you some ideas as to which kind of card yo get.

Hi Frank,

My name is Pradeep and I work for Dell's Social Media Team.
Please start the system in Safe mode with Networking and let us know if you are able to access internet.
Go to, Start, Run, type cmd and click OK. Now type ping www.Dell.com. check for packets sent and received. if the loss is zero, then it is issue with web browser.
If not, please type the commands below:
netsh int ip reset reset.txt
netsh winsock reset
regsvr32 urlmon.dll
regsvr32 softpub.dll
ipconfig /flushdns
restart the system and let us know the results.

The *ONLY* place inside a desktop computer for a fuse would be inside the power-supply unit. Expressed differently, there are *NO* fuses being used.

There is no need to "disable" firmware updates.
The computer will only accept "valid" updates.
So, how would somebody be able to access your computer, in order to try to update the firmware. Prevent access to your computer, and you will have prevented the firmware from being updated.

Dell Optiplex... | Answered on Oct 24, 2014


go into your Dell Maintenance program, or whatever it is called in the All Programs list under Dell. If it has updates listed then turn off or change setting so that updates are either not done or require your approval/management. Else, if your model does it thru Windows Update, do not do it! Hope that helps.

I used google to search for i/o panel of dell optiplex 755 and got his link http://www.discountelectronics.com/product?gclid=CKTSgfHdscECFeHm7AodD1wA3w&product_id=7297&product_model=18

Dell Optiplex... | Answered on Oct 16, 2014


yes the power switch is called the i/o panel it connects to the system board of the computer by a wire or ribbon cable. You have to unscrew a screw.
HERE IS THE MANUAL LOOK ON PAGE 70

Probably nowhere. A desktop is not made for that, so I have a Mifi (MobileWifi)
Mine is from Vodafone and is a Huawei enclosure with SIM card slot. this Mifi sends out a Wifi signal I can connect up to 5 computers, tablets or desktops with Wifi-card to.
so for this solution you need:
1. A Wifi-networkcard in your desktop. Laptops do have it standard, because they are meant to be mobile devices.
A Wifi- network card for desktops to be installed inside the desktop.
You will need to install also a driver from a disk or download from support site from the manufacturer.

2. A Mifi where the SIM can be inserted.
Do a Google search for mobile hotspot to find a Device for that.

these can be related as the main battery on the motherboard is need to retain cmos setting when a system is unplugged from a/c power for extended periods of time.
so the loss of cmos would prompt you about certain components including amount of memory(pending no changes in memory amount/ slot location as a single chip unit must have the mem in slot 1). there is a round 3.0 volt battery that once reports bad, should be replaced. start there and see if you get any other errors. as there could be a problem with the powersupply or motherboard if that doesn't resolve it.

It generally means that the computer can not find its Bios. Try unplugging the computer for a bit and retry. I may work.
