Preferred Solution: Dell Optiplex 755 SFF issue

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Dell Optiplex 755 SFF issue

This is a memory error.
Unplug the system, hold the power button for 30 sec and remove and reinstall the memory module(s).
If that doesn't clear the error, try one memory module at a time in each socket until you find the bad module -- or, if more than one module fails to work in a single socket - the bad socket -- and replace the corresponding faulty part -- the memory module, or in the case of socket failure, replace the mainboard.

I'm from Pakistan, recently I've purchased more than 20 dell optiplex 3050 with LCD E1916H. Most probably all the system are doing same issue which discussed above by many users. I connected the LCD with DP cable to CPU, nothing happens wrong until i opened Microsoft excel, watching YouTube video and sometime when switching from one tab to another in browser. On accessing these app, monitor display get disappeared while power continues coming. All the staff are suffering with trouble, plz giveimmediately some solution.
OS: Window 10 pro (64bit)

A:Dell Optiplex 3050 with dell lcd E1916H generating display issue with some application

The culprit seems to be the hardware acceleration enabled in the Intel HD driver. But, I have yet to find a way to disable it universally across the Windows 10 operating system.
For Office software =* Start any Office program* On the File tab, click Options* In the Options dialog box, click Advanced* In the list of available options, add a check to, "Disable hardware graphics acceleration"* Click OK
For all other software, you will need to check into their specific settings.

Hello, I own a Dell Optiplex 745, running Windows XP Professional 32-bit. The Dell System Direct isn't launching, even though it will download, it says .APPLICATION, which cannot be opened. Does anyone have a fix?

A:Dell Optiplex 745 - Windows XP Pro 32-bit Dell System direct issue.

The older versions of Dell System Detect are security risks - if you're running an antivirus program, it may be flagging and intercepting the program.  At any rate, you should NOT be using Windows XP online at this point, as it has seen no security updates in almost two years - you really need to upgrade to a supported version of Windows (at this point, that's a minimum of Windows 7).

I have a Dell Optiplex on the way from e-bay and I would like to go ahead and order some more ram so they get here about the same time but I am having a hard time finding out what ram chip to get for that model.

I normally don't have a problem looking up the correct ram but I am getting suggestions for PC-2-5300 and PC-2-6400 as well as some others. I know that it uses DDR2 but the rest is confusing me. I understand the chip speed such as 667mhz or 800mhz but the rest I am unfamiliar with.

Could someone please tell me what type of ram chip I need to get? I am going to get 1mb sticks so I don't care if they are exactly the same as what comes with it because it only comes with 215mb of ram so if I get one with a faster speed then it won't matter cause 215 mb is nothing for ram. Please help me with what ram chip to put in this unit if anyone can and thanks.

I'm running WinXP w/SP2 on a Dell OptiPlex 740. I have an application that requires a barcode scanner to be connected and configured (via serial) to COM2 only. By default, the 740 has COM1 which I was able to manipulate and change to diplay COM2. Also, I changed the interrupt request to 4 and I/O range to 02E8-02EF. This configuration works... until I reboot the computer. At that time, the printer is no longer recognized by the application and it appears that Windows has reveresed the IRQ and I/O settings that I previously set. I have tried rebuilding this machine with Win XP but still get the same issue. Is this a problem with the HAL? A similar set up worked fine on OptiPlex GX150. The HAL on the 740 is currently set at ACPI Uniprocessor PC. Should I switch to Standard PC HAL and avoid the virtual IRQ setup altogether? Does anyone have any suggestions on this?
 

A:Dell OptiPlex 740 Com port issue

Creating a hardware profile after you have the configuration working and
using that profile to boot may retain the settings.
As it is now,windows is booting to the default profile.
To create a hardware profile
You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings might also prevent you from completing this procedure.

Open System in Control Panel.
On the Hardware tab, click Hardware Profiles.
Under Available hardware profiles, click Profile 1 (Current), and then click Copy.
Type a name for the new hardware profile, and then click OK.
You can customize your new profile by enabling or disabling devices for that profile in Device Manager. For more information about Device Manager, click Related Topics.
Notes

To open System, click Start, click Control Panel, and then double-click System.
The profile named Profile 1 (Current) provides a model for you to create new hardware profiles. It will not appear in the list of available hardware profiles shown during startup.

A:issue with dell optiplex usff 760

There is no way to know for sure. Typical causes of shutdowns, as you noted, are the power supply and motherboard. The only way to truly "test", is to swap one or the other and see what happens.

The fans "buzzing" (ie: running at full speed) is common for some PC's as the PC boots.

Hey,Dear i have problem with my desktop dell optiplex 9020 the problem is when i tried to power on it is not powering on but i can see that the power button is still orange but it is not powering on.

A:Power issue with dell optiplex 9020

Hi ,
Thank you for writing to Dell Community Forum!
Here when the power button is  orange it indicates that the system is receiving power but not sufficient power to transmit it to the system's components.
However I would suggest you to try these steps and advise the result ,
*Disconnect the system from wall socket and press ,hold the power button where in we are releasing the static charge from the system ,then connect the system back to the wall socket and turn on the system .
*To confirm if the power supply unit is working fine would ask you to perform the power supply unit Built in self test where in behind the system where the power cord connects to the system you will be able to see a tiny black button with a green radial bulb next to it .When that button is pressed if the green light glows then power supply unit is working fine.
*Confirm the power button has a steady orange  light or blinking orange and also if you hear any beeps from the system .
Can you also provide your computer model ,service tag of the system (via private message) to perform model specific troubleshooting. Hope to hear from you soon.
Have a great day ahead !
Kindest Regards,

Having an issue with a Dell optiplex 9010 AIO not performing its normal POST behavior. When I press the power the machine starts lights,fans kick on but no Dell log indicating POST. The computer will shut off after a few minutes and try to start again. I am not getting any amber lights or beeps the power comes on and the fans spin up their is no POST. I tried connecting an external display, unplugged all the devices, tried another PSU and RAM.
I believe that the issue is either the motherboard or the CPU and i'm leaning towards the motherboard.

I did a troubleshoot and found out that networks status changed from work to public. Error on network icon is "Unidentified network, no internet access". I did ping our router but timmed out. I can ping other servers & PC's on the same network but cannot ping the router or default gateway. I did the following

1. ipconfig /release or renew-did not work
2. ipconfig /registerdns/flushdns - did not work
3. Disabled network card or enabled it - did not work
4. Changed IP address from DHCP to Static - did not work
5. Updated, uninstalled, repaired network driver - did not work
6.Changed Speed/Duplex settings to 100Mbps, 1TB or Auto - did not work
7. Removed other networking services - did not work
8. IPReset All - did not work
9. Removed all Antivirus softwares -did not work

Recently our Dell Optiplex 330 experienced some pretty severe virus attacks that render the computer useless. The user had disabled the installed protect advising that it slowed his performance and would not let him install cute little things from his favorite social network. The machine was so hosed it was determined the best course of action was to reformat the drive and basically start over. The problem is this unit was sold to us by Dell with a license for Windows Vista Business which we request it be down graded to XP service pack 3. Each time we attempt to reinstall windows xp from teh provided original disc we get the famous blue screen advising there is a problem with the hard drive, etc. How can we reinstall the our favorite XP? The unit has a SATA hard drive. Any assistance would be greatly appreciated.

 have recently taken delivery of 150 Dell Optiplex 3040 PC's all with the same specification.
I am trying to image then using MDT.
Before taking delivery of all the PC's I took a sample of 2 to test with to make sure I could create an image and deploy it. This worked without any problem using Litetouch and a defined sequence. Happy days.
I then took delivery of the remaining PC's and tried to apply the same image. However this fails on every PC I have tried apart from the initial 2 samples and it is driving me crazy. PC spec is identical for all PC's and there is only one W10 cab available from Dell that I am using for drivers.
I get a black screen  stating
windows failed to start. A recent hardware or software change might be the cause.
Status Oxc000001
A required device is not connected or can't be accessed.
This happens as the process seems to be connecting to the Litetouch image so I think it might be a possible NIC issue, even though it does successfully connect to the WDS deployment server.
Any suggestions?

Hello,
I recently purchased a Dell Optiplex 780 MT from Ebay. The computer has the following specs: 
Processor: Q8400 2.66GHzMemory: 4GB(4x2GB) DDR3 RAM
ATI Radeon HD 3450. 
My issue is between owning the computer for a few months, I have been using the on board VGA port and recently purchased the DMS-59 to VGA and DVI adapter. When I installed the graphics card I get a message stating that the configuration is unknown and that I need to unplug the monitor from the display port. The problem I have is that with the VGA plugged into the adapter to the 3450, I get no video output. Now I have tested it on a different system and the card worked. I also changed g the configuration and turned off the message for video cards in the bios and have updated/ downgraded the bios as well. Does the system not support this card? or do I have a bad Motherboard?
Thanks

I have a problem with a batch of Dell optiplex 980's, for some reason the Main boards fail at a alarming rate.

According to Dell it is the memory controller that fails.

Error Lights 1,3,4 are on nothing on screen, power led solid blue about 10 error beeps!

Dell tech replaced the main boards and all is fine for a while but same problem persists.

Also according to Dell level 6 tech, it could be over heating, I had some fun proving them wrong, two PC's sealed in a box , hammering them, Temp between 85 Celsius - 90 Celsius in the sealed enclosure, optical drive started melting, cooled the PC's for a day and powered back on, no problems!!

Does any one out there maybe have a issue similar to this on the optiplex 980, main board failures?

I have an Optiplex 760 small form that I recently had to reinstall Windows 7 due to a hard drive issue, I am running Windows 7 Enterprise 32bit, I have 2 Gigs of Ram and a 3.00 Core2Duo processor. After the reinstall of Windows I am not able to set the proper resolution of my Dell 1909wf (widescreen monitor) the proper resolution of 1440x900, I am not able to select it. I have my monitor connected though VGA as that is the only connection on my computer. When I go in to Device Manager, I have a little warning triangle next to Intel (R) 4 Series Internal Chipset. When I click on properties of the Intel 4 chipset, the error is:

This device cannot find enough free resources that it can use. (Code 12)
If you want to use this device, you will need to disable one of the other devices on this system.
I have downloaded the drivers for the graphics card and for the chipset directly from Dell by entering the service tag and have rebooted my computer several times with no success. I have even had Windows search for the latest update and It says I have the latest driver installed. I also have a warning triangle on Intel (R) Management Engine Interface. Keep in mind that my computers graphics card worked great and had the proper drivers on 7 before the hard drive was re-imaged. I have other 760s with the same specs and monitors that have no issues. I can post more screen shots if needed.


Thanks!

Welcome to Seven Forums.
Go into device manager and see if your monitor is listed.
If it is listed as pnp. I would suggest going to Dell to see if their is a.inf file (driver) for it and install it.

Installing the .inf file should get your monitor recognized and this will allow it to run it's native resolution.

Hi everyone:

I was curious if anyone else experienced this issue? I have a Dell OptiPlex 7010 desktop/mini tower that I bought off the official Dell site. I configured that mini tower to have an SSD drive as the main drive, which I like very much, except one very annoying issue. Sometimes out of the blue Windows 7 will hang up, I can't click anything and the mouse starts spinning in a circle. This continues on for about half a minute and then it always comes back to life. Suddenly I start getting all my previous clicks moving windows, opening things, etc, all at once. This happened at least a dozen of times by now and I started to notice that when this happens the HDD/SSD LED on the case glows solid, which made me suspect that there's something going on with the drive itself.

Does anyone know what's going on and how to fix this?

PS. I tried contacting Dell support about this issue but they are pretty useless. I spent several hours in a chat with a guy once that eventually simply hung up on me. Then I emailed someone at Dell, for which the guy replied with instructions to run their hard drive diagnostic tool, which I did, that did not show any errors. (Note that I don't have a hard drive, it's a solid state drive.) I replied to the guy only to never hear from him again.... So I think I'm pretty much done with the Dell support

Also tried disconnecting all external cables (ie headphones, ethernet etc). Powered on and off multiple times and no change. 
By the way, I don't know if this is related or not, but last night before the issue occurred, I was randomly logged out. Once it logged me back in, everything was closed and there was a small square of like TV static towards the bottom right corner. I restarted and it fixed the issue there but I don't know.

Dell Optiplex 755 won't turn off and the monitor won't start. When we start the desktop the monitor stays in a sleep mode, movement of mouse or pressing a key on a keybord doesn't help. When we try to switch off the PC it turns off and immediately turns itself back on. Don't know what to do.
Thanks

Trying to fix this thing up for my grandaughter. It has a 200 mh. processor 128MB ram and a 40GB hard drive. Now it seems that the mb. drive controller is inop. At least that is what it says when I try to boot. I was told that it wouldn't support the 40 GB drive anyway so I bought a PCI ATA card. By the way I installed a 6GB. drive to see if the MB.would boot it,and it said the same thing. How can I get it to boot? It seems impossible because I need the PCI card to get to the drive and the system needs the driver for the PCI card to run the drive. Is there any chance???

I need information about the following:
I owe a Dell Optiplex 745 sff running Vista Business,
hard disk is a 80 Gigabyte sata
The hard disk is almost full and I wish to take it out and replace same by a 2.5" sata hard disk.
Can anyone tell me whether this is possible and if so how to go about it?
Because it's a small form factor it can only hold one hard disk.
Your advice will be highly appreciated and thank you beforehand.

Hi, I'm looking for the type of RAM and how much RAM the Dell OptiPlex 765 can upgrade to.  I've tried to look up the specs, but I can't seem to find an OptiPlex 765, yet my in-laws have one.  It only has 2GB of RAM.  I believe I read the 755 supports 8GB of DDR2 RAM, so I would think the 765 should support that  much as well.  If someone could send me a link of the specs and/or RAM it takes, I'd really appreciate it.  I can find posts about the OptiPlex 760 too, but no 765.  I've found this regarding the 760 series, which I'd think the 765 fits into, but I'm not certain because I can't find anything about any OptiPlex 765, but I've seen the computer myself and that's what it is.  If it's the same, then it should support 8GB of DDR2 RAM as seen from here

That model does not exist on the Dell website for driver support. www.dell.com/.../optiplex_desktop

Hi!. I got a not so new Dell optiplex 745 with a old Intel Pentium 4 530 @3.00Ghz with 1gb of sYstem RAM, a 80gb seagate hard drive, a 305w power supply And integrated intel gma 3000 graphics, my question is, Can i replace the old Pentium 4 that is 90nm with a Pentium e5500 or a Core 2 Duo e6750 that are 45nm? also, i will buy a geforce gt430 and a 2gb dual channel ddr2 memory. does the power supply support these three components? also is this a good computer or should i buy a motherboard and install everything from the start?

A:Help With Dell Optiplex 745

Minitower Optiplex 745:
Supported microprocessor types: Intel® Pentium® 4, Pentium® D, Celeron®, or Core™ processor
DDR2 RAM should be installed in matched pairs so you'd need to install 2 of them. But there's no point installing 4 GB of RAM with a 32-bit version of Windows which can only use ~3.0 - 3.5 GB of RAM. Note, this system supports 2 GB RAM modules but only those running at 533, 667 MHz. It doesn't support 2 GB modules running at 800 MHz, but apparently will support smallar modules running at 800 MHz.

Hi everyone,

I have been looking up about getting a replacement for my existing CPU which is an Intel Core i5 (Version: 2400) and upgrading to the new Intel Core i5 4460 which does support HD better for what I needed, such as movies and gaming (I only need up to 60FPS).

But other than that, I have been looking either at a portable GPU. The GPU is called a Zotac GeForce GTX 960 4GB (from NVidia). I just want to know if this will fit and will it work well with my PC?

I just want to know if the new Intel Core i5 4460 will fit in the Optiplex 390's motherboard, the same for the Zoatac GeForce GTX 960 4GB GPU.

But I would be interested to see what you have come up with any other CPU/GPU recommendations for this Dell Optiplex 390 Desktop.

Many thanks,

Ben

Which graphics card could i use in a Dell Optiplex 745 maybe a EVGA GTX 750 Ti? Or is there somethings different i could use?

A:Dell Optiplex 745

It depends on your case, the specific card and the power supply you have.  That card is overkill for a system that old and a CPU like the Core 2 in it.
You'll need the minitower case at minimum (forget about the smaller ones) and may need a new power supply if yours isn't up to powering the card -- or if the card requires a separate power tap, which your power supply will not have.
