Preferred Solution: DELL OptiPlex 3046

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 (This link will automatically start a download of Reimage that you can save to your computer.)

Answer: DELL OptiPlex 3046

Dell doesn't provide this. Dell Wont provide this. You can buy an adapter that likely works fine. The 4 pin EPS12v motherboard connector is the same. The 24 pin must be converted to 8.
The current moddiy adapter has more than just passive pass thru it has a circuit board with other "stuff" on it.

Dell Main Power 24-Pin to 8-Pin Adapter Cable. YMMV
Seems to be using the Grey PWR Ok, 3 Black Ground Wires, The Power On/Off Green Wire, the 2 12V Wires from the 24 pin and 1 12v Wire from a molex power connection.

I'm having an issue installing windows 7 on a Dell Optiplex 3046.
everything goes well excepted when i'm trying to install the USB drivers on my computer.
I tried using the windows 7 full package, i tried to download the USB package appart from the others, i tried to get them from Intel and even tried to use windows update to get the drivers from them.
Everytime i get the same result : mouse and keyboard both don't work.
Is there an easy fix i haven't tried yet ?

I was planning on buying either a Dell Optiplex 780 SFF or an Dell Optiplex 980 SFF but I would like to know which one will work with Windows XP 64 Bit.

Answer:Will Windows XP 64 Bit work on a Dell Optiplex 780 SFF or Optiplex 980 SFF?

For Windows XP 64 Bit its best to use the somewhat hidden (old ftp website):
This has the old drivers listed of multiple versions including the XP x64 drivers not mentioned on Drivers and Downloads. The new ftp website is slightly broken at present.

An access database which has been running for over a year has suddenly stopped allowing more than one user to login at once. If more than one tries they receive an error number 3046 Couldn't save; currently locked by another user.

The backend is an mdb file sitting on an novell netware box (no changes have been made to this server)

I've tried repairing the database, both front and backend, as well as creating new mdb and importing the old databases components.

An old but functional version of the frontend works fine via a citrix server.

Anyone know what could cause this issue?

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?

Answer: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).

When the PC starts up, the dell loading screen begins. Normally this takes around a few seconds but this time it didn't end. We've tried all the diagnostic tests and they all came back fine. 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.

Sounds like a faulty hard drive is the cause - F12 at powerup.  Boot to the Dell diagnostics and run an extended test (not just the quick test) on the hard drive -- you'll likely find it fails, in which case - replace the drive and reload.

my guess would be that this was after some kind of storm or power surge. can you see the bios loading? in order to diagnose this you will have to have parts that are known to be good and go through the machine one piece at a time. The main suspects right now is the power supply, CPU, or the mother board. Do you get any audable beeps when it is trying to start up?

I was trying to install windows Xp sp2 on a Dell computer: Optiplex 755. When the software reach that step: setup starting windows a blue screen display saying windows has been shut down to prevent damage, check for viruses, check your HDrive, etc?
I removed that HDrive, and I installed to another Dell computer same type (Optiplex 755) I started the process of that windows Xp sp2 (installation) everything was fine. Now I switch back the HDrive to the first Dell Optiplex 755. I power on it started loading properly when it?s about to reach the screen that has the recycle bin. The blue screen display again with the same message, windows has been shutdown to prevent damage etc?, at this point which one to accuse the memory or the Bios, any help will be greatly appreciate.

Answer:Dell Optiplex 755

That PC uses SATA drive controllers . . Installing XP on a SATA drive requires an additional step:

However, Most newer BIOS allow an Alternate method for SATA . . Go into the bios and check the "Sata Operation" setting,

change it to "Raid Autodetect/ATA if it is not already. Now try to install XP ( could be IDE Mode, Compatibility Mode or Legacy Mode - different BIOS use different terms )

some will say IDE instead of ATA)

If there are no such settings you'll need to slipstream the sata drivers on the XP CD, follow the instructions in this guide :


You can get a reinstallation guide specific to your Dell here

Are you using the Dell Reinstalltion disc? . . if so is it SP3? Those have the Intell SATA drivers

Answer:Dell optiplex 780 mt

There's not much you can do with these as far as gaming goes - the power supplies are not going to handle demanding video card, and the chassis and mainboard are both proprietary.  
It'll perform just about the way you expect a nearly decade-old system to perform -- if you want the best you can do within the limits of a decade-old processor, replace the hard drive with a solid state drive.

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?

Answer: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.

Hi all,
I've got a Dell Optiplex desktop (DT) 755 at home which I'm in the process of converting into a PFSense router and firewall. I've got gigabit fibre coming in, and I'm noticing throttling at around 700mbit speeds, which I believe is down to the PCI bus.
Question is - can I use the PCI-E x16 in PCI-E x4 mode for a network adapter instead of a video card? Would an Intel EXPI9402PTG2L20 Intel Dual Port Gigabit PCI-e Network Card SFF fit the bill and what can I expect in terms of speed? Even PCI-E x1 would suit my purpose.
Any experience doing this would be helpful, I'm on latest bios version A21

No you can only use the X16 slot with video cards.

This is a continuation of my earlier thread which says it is locked:

Alas, the unit recommended to me in that thread is sold out.

I have been looking at similar units of the same model number but, as best I can tell, although they have the same name/model, the Dell Optiplex 780 seems to come in two different case sizes, a MF and a SFF, the SFF being the smaller of the two.

The SFF seem to be the more plentiful and about $50 more expensive, while having only 1TB SATA compared to the MT having 2TB.

Am I right in thinking that there are indeed two case sizes; and, if so, which is the preferable ?

Hello,I purchased an Optiplex 380 a couple of years ago which came with 2x2GB RAM @ 1066Mhz and now I think time has come to upgrade to at least 8GB. So, I tried a kingston value ram of 4gb @ 1333Mhz and unfortunately it beeped with 1 and 3 diagnostic LEDs lit. I know that the Dell manual says a maximum of 4GB ram but I have seen people here on dell forums running 2x4GB without any problems, so according to my thinking, maybe the bus frequency is the problem? shall I try 1066Mhz? Crucial's site also suggests up to 1600Mhz so whats the confusion here?P.S. I have latest BIOS A07 flashed.

Answer:Dell Optiplex 380 max RAM

Thank you for reaching out.
Did you try 8GB(4+4) or Does it beeps even with a 4GB stick in one slot? 
Try each stick on both the slots, If that fails, you may try 1066 mhz.
P.S:  We haven't tested 8GB configuration on this motherboard from the factory, If none of the steps works, You may have to revert back to 4GB.

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,


Answer:New CPU/GPU for Dell Optiplex 390

Because the optiplex comes in three form factors, which one is it? The Desktop ones? or the smaller one?

Anyways, to be able to upgrade to a Haswell processor you'll need a new motherboard aswell (Those with H81 chipset will do). The Zotac GTX 960 will work provided you have enough juice from the PSU to be able to supply the graphics card

Question: Dell Optiplex 780

I like my ten year old computer.  I've tossed the original 250G HD (and Windows too) in favor of a 1000G HD with Linux Mint 18.1.  It behaves perfectly and is quite fast.
I greatly appreciate the quality of the case.  Nice metal which is easy to open without a screwdriver.  But I have some questions.  I understand the maximum RAM is 8G.  Does anyone know if this is true because I want the maximum whatever it turns out to be.  
I rescued this computer from recycling and bought a new monitor for it.  Why anyone would throw away such a nice computer is a mystery to me.  Sure the display output is analog but there are two unused PCI slots.  I can add a digital card with HDMI plug I think without using an external converter which requires it's own power source. This way I can use my smart TV as a monitor.  Do I need a wireless card?  If it were a laptop I'd say "yes" but since it will never be moved around why bother?   I will add a graphics card though to get a visual boost.  I have no need for a high end gaming machine.  I'm in my 70s and low end games are all I can manage.  Besides I do not care for the violence that most of them seem to thrive on. 
If anyone can verify the max RAM I will be grateful.

I just purchased a (barely) used Optiplex 960 from my office (my employers often sell used equipment to employees if they want to get rid of it).  It's in great shape, clean, and all the hardware seems to work, except for the fan speed controller.  I know it's supposed to adjust the speed of the cooling fan depending on how hot the CPU is getting, but it's not doing that.  The fans seem to stay on low / medium speed even when the CPU is pushing 70 degrees C according to Speedfan...which is WAY too hot.  The only way I can get the fan to speed up is by disabling the auto-speed control in the BIOS and leave it on 100% constantly. 
Anybody have any suggestions?  Is the temperature controller damaged, or do these systems normally run hot?  Thanks!

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.

I was looking at turning a older dell intel computer into a NAS and was wondering if it will support a 3 or 4tb hard drive. Emailed dell about  this, and they sent me this reply:
good day to you. The 780 would be having the same limitation in size that come with the storage format of NTFS. I checked on this unit and it appears that it does not support GPT.
So NTFS limits + amount of drives + amount of size for each drive.

Okay so, I recieved a Dell optiplex 745 from a friend who had recently upgraded, it had no disk or hard drive (I've disabled SATA 1 which is where my disk drive would be) when i got it, I put in my old seagate momentus 5400 2 (50 gig (i know i was low on $$)) and have been trying to load windows 7 from a USB, I have tried XP but it always says "boot disk not available, F1 to restart F2 for setup utility" I have run a processor check and a memory check and the diagnostic passes, anyways when i boot from USB it will always say

"windows failed to start. A recent hardware or software change might be the cause. to fix the problem:
1. Insert your windows installation disc and restart your computer.
2. choose your language settings and click next.
3. Click repair your computer

If you do not have this disk, contact your system admin or computer manufacturer for assistance.

Answer:Help with installing win 7 on Dell Optiplex 745

1.512 Gb of ram .. so you have two DDR2 installed ..

Try to remove the 512 mb DDR2 and try to clean the other ram and it's slot , or clean them both .. BUT CAREFULLY DO THAT .

It is better to install xp on this pc ...but I'm wondering why you are loading Win7 from usb any way ! .. this usually does not work !!
Are you installing windows from usb ? it is not a long story to install windows from a flash disk . or even make it bootable just like Hiren's CDs . but usually after several times you must re-make it or it will make problems just as you got .

Also .. BSOD can be caused by not supporting USB as a legasy device .. this can be enabled from the bios .

Hi AllJust bought a second hand tower a Dell Optiplex 755 Core 2 Duo 1GB Ram 80 GB Hard drive ( only 20) so i am not too fussed if i can't resolve this issue.The computer would not boot up ( stuck in a loop) and came with no recovery or driver Cd's. It does however have a Genuine COA Sticker on the case for XP PRO. So i borrowed a XP Pro disk from work and wiped the hard drive to start afresh, all went well until entering the 25 digit key from the case it will not accept it " Invalid Product Key".I have looked in the I386 Folder of the XP Disk at the PID value and it ends in 270 which means it is a Volume Licence CD and is not compatible.So my question is will a XP Pro OEM Disk work with the code on the case, or is it specific to Dell and therefore need a Dell XP Pro disk ?I have in the past used my XP Home OEM Disk on other peoples computers with their code to reinstall without any problems and activate by phone.

Answer:Install XP Pro on Dell Optiplex 755

XP Pro disk will work as long as it is an OEM version. I`ve done this with a Dell machine in the past. May need activating by phone though if I remember correctly.

I I have an old gx620 ultra small form factor that I'd like to upgrade because it fits perfectly where it is and I haven't found any more modern unit that does. It has a pentium d820-2.8 ghz,800 mhz and I would like to go to a core 2 duo (e5200-e5800) if possible. I know it would fit physically but would this mobo support it? I have a gateway that can run both chips but I don't have a clue about the dell. I know it should run cooler, and that should quiet it down- the fan runs hard and loud when it has to start working. If no on the e series then how high can I go on the pentium d series chips? I know the d945 would be a good bit quicker, but again, will this mobo support it? Thanx for any info you may have.

Answer:Dell optiplex gx620 cpu

I don't believe the Core 2 Duo chips are officially supported, though if you updated the BIOS to the latest it may work with the older Core 2 Duos such as the E6300 and E6600 Conroe CPUs.  The chipset should support them but Dell sometimes locks down CPU support in the BIOS.The Pentium D chips aren't worth the money to upgrade to, they're all very slow compared to CPUs released in the last 6 years or so unfortunately, so I wouldn't recommend spending money to upgrade to the 945.

Answer:Add a second HD to Dell Optiplex GX280?

It can if you remove the floppy drive and mount the hard drive in that spot. You'll need to use an IDE cable with two connectors and use it for the CD/DVD and the new hard drive. I don't recall if there was a SATA connection on the motherboard, if so that would be the way to go.

This can happen because big companies like dell, compaq/hp, gateway and some other ones lock their bios and have certain devices that detect if you've opened your case before, and this is their way to tell you that you opened your case and that if a problem happens with whatever you did, then they're not responsible

Please guide and tell me that what is the problem and what to do now?

Answer:Dell 755 optiplex tower pc

What you have is a fail to POST. General diagnostics for fail to POST is
1. Power Supply failure (typically capacitor failure)
2. Motherboard failure (typically capacitor failure)
3. Corrupt BIOS
Since most Optiplex motherboards have a proprietary 24 pin plug they are NOT compatible with conventinal power supply without an adaptor.
You have already had problems with the USB ports which suggests to me the problem may be at the motherboard level. Clearing the CMOS would be my first try at repair.
If clearing the CMOS brings no joy, my next focus would be motherboard inspection for bad caps. If it looks fine, I would test the power supply output for correct voltage on each rail starting with the 5VDC rails.

I am trying to update the optiplex to windows 10.  I have windows 10 downloaded and need to burn it to DVD.  The optiplex has a DVD writer, but seems to see it only as a CD? and is unable, as such, to write the program to the DVD.
I am wondering how to get the DVD burner to work?
Thank you.

Answer:DVD burning on Dell optiplex 740

As long as the drive is seen, it doesn't matter that it is called a cd drive. Right click on the downloaded iso file to burn to dvd.
This might be easier--
Go here instead to update online--
No need to make a boot install disk unless you must do a clean install. There is no free upgrade now. You will have to buy windows 10 ($119-$200) after it is installed so you might want to reconsider installing it on the old computer. And waiting until the creator version comes out April 11th would be wise.
If you must do a clean install instead of an upgrade-- -Burn the iso file you downloaded on another computer if necessary. Boot to that disk and choose custom install. Delete the windows partition and install win 10 on the unallocated partition. Pay for windows 10 after the install is completed.
Be aware-- you will have to use MS win 10 drivers which might or might not work since your model is not approved by Dell. No dell drivers are available. see this

I have a Dell optiplex 745 with pentium d 3.4ghz. recently i began getting blurring and horizontal line on screnn which rectify when disconnecting ad reconnecting the monitor. It has now died. First the thrid warning light was not showing which think indicates a graphics problem which is integrated. i am now getting nothing fromm it. The fan comes on and the motherboard light but no output whatsover. The standby button has gone from green when working to orange which i think indicates a problem?? Any advice to whether it could be a motherboard/ processor or other problem would be greatly appreciated

Answer:dell optiplex dead?

First off, the amber light on the monitor means simply that the monitor is turned on but not getting a signal from the computer. So, I think your problem is in the computer.

These are the possibilities as I see them in roughly their most likely to least likely order:
Bad power supply
Bad video card
Bad main board or processor or both
Bad memory chip

disconnecting ad reconnecting the monitorClick to expand...

Disconnecting and reconnecting a digital monitor can fry a main board or processor.

Hello Forum-I have an old dell desktop optiplex G1. It has worse than lousy 2 mb of video.Appearantly this video is on board as I can see no card, though it appears it has slots to accept cards. I looked every where on the net(or almost), but very limited info is available for the upgradability of this old unit. I seen some video cards(32 & 64mb) on ebay that looked as though they may fit slots, but I`m not sure they would work. Also could this grampa`s CPU be upgraded to say PIII(100or133 mhz bus). If so what parts may I need to upgrade? Thank-You very much for your knowledgeable advice.

Answer:Upgradability for Dell Optiplex G1

Not a lot you can do with that system. I don't believe there is an AGP video slot, but you should be able to add a PCI (not PCIe) video card. It's a Pentium II so the best you could do would be to upgrade to a faster PII. Since it's got a 400 that just leaves the 450 and that would be a useless upgrade.

In the end I can't see that it's worth doing anything with it.

So I have been doing a lot of research on the dell optiplex 780 just so I don't make any purchases of anything that wouldn't work in my PC. There are four things I am really focused on getting upgraded right away before I do any thing else like the hard drive and that is the CPU, GPU, RAM, and power supply. The CPU I am planning to get is the Intel core2quad q9650. Knowing that this is a power hungry card and seeing how I am going to overclock it, the card will make some heat so I am planning on getting an aftermarket cooler. Seeing how I can't really just slap on a coolermaster and be good to go I want to get this  I think this would be adequate for overclocking and keeping it cool, but that's where I need the forums to make sure.  The GPU I will be buying a riser card made specifically by dell for the motherboard so that way my dell optiplex 780 DT will support full height cards and I will be getting a GTX 750 ti. The RAM I wont have an issue with just as long as I can find four 2GB sticks of Non-ECC DDR3 RAM running at 1033Mhz and my computer will support the RAM because I have a 64-bit OS and a CPU that will support 64 bit as well. This is where the problem comes in, I don't know what power supply to get. I want to get at least a 400 watt power supply because, even though it's a little overkill with the amount of power, it will be nice to know I wont have any issues in the future if I decide to upgrade again. So what do you guys thin... Read more

Answer:Looking to upgrade my dell optiplex 780 DT

You can't do any of what you are talking about.
If you want to upgrade get a precision T3400/T3500 or better.
The Desktop Riser slot is only 1 slot wide so a 750TI wont fit.
The power supply is not upgradeable to 400W
There is no overclocking on a 780.

I have a dell optiplex 755 with 305 watt Power supply, Intel core 2 duo E7400 and a 2 GB Ram...i wanted to know weather my board is compatible wirh Nvidia GTX 460.. Thanks..Also plz telll me how to convert VGA into DVI..


Answer:Dell Optiplex 755 -- can I install a GTX 460?

Hello maaz, I do believe a GTX 460 would fit inside of the case, but it would be a tight fit, also, you'd need to upgrade your PSU to handle the new GPU.
How much are you looking to spend?

I just bought a Refurb. Dell Optiplex 760 with Vista Business to replace an old dead desktop. I plugged it in, but it makes a series of beeps, lights up the power button, the fan is running, but it doesn't light up the monitor or recognize the keyboard, or of course, the usb mouse. I've contacted the ebay seller, (99.7% rating) but am wondering if there are any simple suggestions in meantime.Thank you!

Answer:Refurbished Dell Optiplex 760

The series of beeps can be used to determine what the problem is. How many beeps does it do before pausing and is the next set of beeps the same?

Working on this mutha for a friend.
Will not boot up.
Says hit F1 to continue or F2 for Setup.
Neither key gets any reaction.
After several minutes it goes to another page that says "Previous fan failure" and "System battery is low"
Friend knows nothing about any fan failure, and replacing the CMOS battery with a known good one does no good.
Will not let me go to Safe Mode, Setup, nothing.
Machine is a Dell OptiPlex 520GX running Windows XP.
And there is a yellow LED light burning at the bottom of the motherboard.

Answer:Problem with a Dell OptiPlex.

You could try reflashing your BIOS. Dell uses Pheonix for the most part I think, so this might help out:

Failing that, you could try removing non-essential peripherals, and maybe give the 'ol RAM dance a try. Probably not likely it'll solve the problem, but worth a shot anyway. May be a shot mobo though....
