Question about PC Desktops

1 Answer

I purchased a Dell Computer, Optiplex 755 mini-Tower. I was able to load my 3.5 Avid Express Software and it all loaded nicely; however, when I record a digital clip, then place the clip on the time line, and Composer screen, the video shows up of the digitized clip. However, when I hit play, the composer window remains static, but the audio comes through. I can drag the time line back and forth and the clip shows up nicely, however, it will not do rolling video unless I drag the fader back and forth. How can I correct this challenge? Please advise.

Try to verify the video card requirment of the software your using. Or the system requirement of the software.

Try to verify if you install the video adapter driver of your system. if you have not install, you must install it to support your application software.

Where is optiplex 755 mini tower service tag #

This is generally in a few places. It should be on a sticker on the front or top of the tower. There will also be a sticker on the back side of the chasis. It's an alphanumeric string 7 characters long. The sticker on the back may have a bar code above and below it on the sticker. You can also get the service tag from BIOS in most cases.

Hi juan...
You do not have Bluetooth on the Dell OptiPlex 755, but you can buy a "Bluetooth Dongle" very cheaply from the internet.
It is a plug and play you insert into the usb port and then you have Bluetooth.

what model is this small form factor ? mini tower?anyhow, here are the things that you may consider .
if its a small form factor unit then you may need to get a video card that is Low Profile
and also consider the power supply :
The ATI Radeon HD 4650 512MB Low Profile PCIe x16 graphics card should work fine with the 275w PSU.
Max power draw is 48 watts

Will ATI Radeon x1900 run on my Dell Optiplex 755?

Looking at the specifications for the Optiplex 755 line I'm seeing the highest power supply is in the minitower version at 305W. I can't find a document specifying the power requirements for the Radeon x1900, but most benchmark power consumption tests show the system pulls around 280 - 300W with that card installed.
The problem is either your specific Optiplex 755 configuration can't support the power requirements, I don't know if you have the MiniTower, Desktop Tower, Small Form Factor or Ultra Small Form Factor version of the sytem or the card is itself is bad.

I have Dell Optiplex 755 dekstop i have power on problem. Orange colour light is blinking

The problem of blinking amaber light is usually caused due to a bad power supply on the computer. Open the system tower and reseat the biggest bunch pf cable connected to the motherboard. its titled P1 and it the biggest white connector. If the same doesnot resolve the problem you would have to replace the power supply on the motherboard.

Thanks for using Fixya

Dell Optiplex 755 2gb of mem, will not load sleep study graphics, had to double the paging file initial size, is this recommended or what resolution would you use?

I have been doing some testing with paging file sizes and have noted a decent boost in performance by setting the initial and max sizes to twice the amount of RAM installed. In your case 4100 Mb is the custom setting I would try

Sound for dell optiplex 755

You can download the drivers from Dell WEB site, the support download page. Make sure you select your model laptop, better still, type in the Service Tag number, it is printed on the label on the bottom of the laptop. This will open the page where the specific drivers for your model laptop are located. Also make sure you select the Windows XP or Vista version of the driver for your Windows operating system.
