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.)

As long as you have a PCI express socket on the motherboard, that card will work. You may need a power cable adapter to be able to connect the card to the power supply

Hi, I might be able to buy a second hand Optiplex mini tower and I would like to install the motherboard etc. of my Optiplex 755 SFF.

Wilt thi fit?

The idea is that with the Mini Tower I can buy a better GPU.


A:Does motherboard of Optiplex 755 SFF fit in a Dell optiplex 745 dualcore mini tower?

No it wont fit.   The board layout, number of slots etc is different.

I purchased the dell 990 and 7010 motherboards I'm using for builds. Each motherboard has two PCIe X16 slots and I'm hoping I can set these up with 2 graphic cards in crossfire in either motherboard. I will be using a 600 watt PSU for each of them and I have 2 Sapphire R7 260X cards I'd like to use in crossfire in one of them. Is that possible? Are these motherboards crossfire and/or sli compatible?

A:I Purchased 2 Dell Tower Motherboards. The 990 And 7010. Was Wondering If

I am a bit confused. And sadly, you did not give us complete information to go on. Most people don't buy motherboards from Dell, except for repairs under warranty. Did you mean you bought two Dell tower computers? If so, specifically which ones? And what is the brand and model of the PSU, and the Sapphire cards. Note there are 6 different models of the R7 260X.

Note that CrossfireX is used with AMD cards (which your Sapphire's are). SLI is used with NVIDIA cards. Same difference - the idea is the same, to strap two cards together for better performance. And yes, depending on the specific Dells you bought you should be able to use both cards. But I note there is a SFF (small form factor) 990 in a slim case. That may cause problems. If this is the 990, then you should be okay for space. But adequate cooling may be a problem. It is the case's job to provide an adequate supply of cool air flowing through the case. Same issues with the 7010. There are several models within the 7010 line and space and cooling may be issues.

I also worry about your PSU. Sadly, many cut corners in the budget and fail to get a quality 80 PLUS certified power supply. It's like buying a new Porsche then filling it up with generic, possibly watered down fuel at the corner Tobacco and Bait shop. Not good. According to user manual (click Download then scroll down) for the R7 260 card (all models), it says 600W "minimum" supply with two 6-pin power connectors with 2 cards. If you don't have a quality, name brand supply, I would not use two cards.

Hello experts,
I am really frustrated with my dell optiplex 745. I have been endeavoring to get on when I replaced the power supply but with no success. I have also changed the motherboard and again nothing to be happening. The dell powers up just fine and then the cooling fan goes noisy. There is a green light in the front panel show showing the numbers; 1, 3,  and 4.  I would be grateful if you can help me with this issue.

We currently have Dell Optiplex 7010 tower in our office. It's using a single Acer G6 G276HL monitor via DVI-I port on the video card. We were thinking to buy a second monitor and I want to know if it's going to work?
The video card inside this Dell is AMD Radeon HD 7470:
I was thinking to get the same screen: issue is connecting it to the display port on the Radeon card. So I was thinking to get this adapter:

A:Trying to set up second screen for Dell Optiplex 7010 tower

I presume you're using a DVI-D cable since the current monitor doesn't support DVI-I which the video card supports.
Why not get a second monitor that supports DisplayPort and go directly from DP on the video card to DP on the second monitor without complicating things with that DP>DVI-D adapter?

I Have Dell optiplex 745 With 3.4 Ghz Pentium D Processor with 4MB cache Memory .... Recently I wanted To Upgrade my p.c to dual core 2.6Ghz  E5300.. when i put Dual core processor into my board and truned on p.c the all lights was green and fan was running too fast and mY lcd Does Not dsplay anything .... And also My bios version is 2.6.3 .. what is the main fault in it.... kindly anyone tell me.... what should i do ???

A:Dell Optiplex 745 Mini Tower Upgrade

Hi Asfand_Munib,
Before installing a new processor, please update the BIOS to latest version from Here.
Note : Please save and close all running programs and documents and disconnect all external peripherals (printer, flash drives, external hard drives, etc) and connect the computer to a surge protector before updating the bios.
If all the lights are green and you are not receiving any beep codes from the system then it means that the processor has been installed correctly. Please check if the keyboard lights (Capslock, Numlock, etc) respond when you press the corresponding keys. Please verify the connections on rear of the system and check if they are connected firmly. Also, check if you are able to hear any windows jingle sounds after some time when you power on the system. Please share the exact model of Optiplex 745 you are using as it comes in 4 form factors viz Ultra Small Form Factor (USFF), Desktop (DT), Small Form Factor (SFF), and Mini-Tower (MT). A picture is attached below.

Please reply with the information. Will take it further from there.

I intend to purchase optiplex 7040 MT for gaming purpose. So I would like to know:
1. Does the motherboard have standard CPU and motherboard power connectors or proprietary ones?
2.  Is it possible to replace the stock PSU with a cooler master extreme power plus 600W? If no, then what size /kind of PSU will fit there?
3. Is it possible to fit a gtx 1080 in there?

The hard drive cage isn't the only problem.  The power supply is not standard.

When I start the pc up normally with the monitor plugged into he card I get the startup screen but then it goes blank. I can plug the monitor into the PC's integrated vga plug and see the display fine on screen.

If I start the PC in VGA mode I can see the desktop but if I go to the control panel and change the screen resolution to a higher one it just goes blank.

Q9650 is max.  Bios update should be done BEFORE trying to change cpu.

 750 TI only fits in the TOWER and Only After Cutting the Bracket off and ONLY with Short cards with 1 fan aka 8.4 inches max.

There are no single slot cards.   If one was put in they hacked the bracket in half or removed bracket altogether.  If you remove the bracket on EVGA models you can use tin snips to CUT OFF half the bracket.  The cooling vents are blocked so you might also have to drill holes in the case to let air out.  Long Cards with 2 fans DO NOT FIT and WILL NOT EVER FIT into the Tower or any other size.

Only Short cards with Short fans Fit.

Hi ,
Thank you for writing to us ! 
To understand the cause of this issue I would ask you to try these steps and advise the result ,
*Disconnect the system from wall socket ,then press and hold the power button for about 15 - 20 secs .Then connect the system to wall socket and try to turn on the system .Here we are trying to release static charge from the system .
*Then disconnect all the peripheral components from the system and try to turn on the system .
*If the above step fails then remove all the memory modules from the system and try to turn on the system with only 1 memory module at a time .
If there are any more queries do reply to this post with system service tag sent via private message .
Hoping to hear from you soon .

There is a design problem with the OptiPlex 7040 Mini Tower case that leads to excessive noise. The plastic grid panel on the front of the case rattles loudly, especially when the system is operating under a heavy computational workload. I'm not certain if the vibration originates from a fan or from the hard drive, but it's clearly causing resonance in that plastic front grid panel. I'm certain that the front panel is what's making the noise. The noise goes away completely if I press my finger against the front panel (and resumes immediately when I remove my finger). My current workaround to the problem is to prop up the front of the case with a piece of bubble wrap. Dell's engineers should consider altering this case design to address the vibration problems.

You can't reach the expansion bays and the case design is horrible.  It reminds me of the old style Acer PC's that ended up being throw aways.  Sending this one back right away.  Biggest flop I've seen in a new Optiplex!

Hi, Currently I'm using a dual core 6850 and I'm thinking about buying a quad core. I have a PSU of 500 W as spare.

Can i replace the CPU to a Quad Core without changing the cooling system?

A:replace dual core CPU by quad core what about heatsink? in Mini Tower 755 Optiplex

These are the specs of the spare PSU. Aren't they better than the original Dell PSU?
That power supply is ATX and not EPS12V
Better is not the issue.  Dell power supplys are 80 percent efficient not 70 percent ATX.  The -5v rail is an issue as well as this may cause a motherboard fire or damage your system.  Its a dead giveaway that this is a power supply from 1990 to 2000.
What current is on which rails is not trivial. There is a single 12V RAIL on that unit and its max is 17A
EPS 12V units have multiple rails of 12V @ 18 amps each.  MAX Power on the 12V rails is 264w not 204w
That unit has a lot more on the 5V and 3.3V rails at the expense of the 12V rails and CPU 4 pin connector. So no that spare unit is not likely to work well if at all.

Recommended update or replacement is EVGA 750B1

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.
Thanks in advance, Sean

Looking for feedback on this new desktop. I am looking to replace a Dell XPS435T / 9000 that I purchased in April 2009 which has served me well.

1. Does the XPS Tower VR require s "Pure Sine Wave" UPS like the XPS435T / 9000?
2. I am planning on having a total of there hard drives in addition to the SSD. Based on the information that I have seen this seems to be possible.
3. I am also trying to determine exactly what 512GB M.2 SSD is being provided.

I have been buying Dell XPS computers for the past 15 years (I have 6) and I don't understand the new XPS tower.

Why does the Dell XPS 8910 have a laptop optical drive instead of the standard 5.25 desktop optical drive? I always thought of the Dell XPS as the top of the line consumer computer, but laptop optical drives are less reliable and have poor read/burn quality compared to desktop optical drives.

Did Dell really remove the front 5.25 bays from the tower? Why would they do this on the XPS tower?  I need the front bays to install two 5.25 optical drives.

I see the XPS 8900 has the standard drive and bays, but is that model discontinued? Are there other Dells that have the front 5.25 bays? It appears Dell also removed the bays from the new Inspiron desktop line.

Hello All,

I have a Gigabyte K8NS Ultra 939 MoBo which is rated at their website for:
AGP 4x/8x (with a latch) ? supports only 1.5V video cards. Right now I have a vgc that is 128mb and want to move up in the world. My question is this. If I get a new vgc that requires a power supply from the psu, will it still work on my motherboard. I know I will have to get a nEW psu seeing as my current one is low grade but I was wondering if my MoBo will even run a vgc that needs power from the psu. My current vgc draws power directly through the AGP slot.

We have a Dell Precision Tower 3620 and have purchased a firepro W7000 to install. only problem is the 6 Pin connector provided by dell has a different pin arrangement. the middle top pin as you look at the plug is square instead of the usual rounded corner pin so will not go into the socket.
Anyone know why this would be?

The only video cards validated in the Precision T3620 did not need the power supply lead. So this may be why the 290w PSU is lacking the correct cable? Perhaps another Precision T3620 can open their case and also check the PSU cabling.

Hello my name is Sebastian Todd, I've been using my dell computer for more than 2 years now with absolutely no problems affecting it, due to my proper maintenance. About 1 month ago, I turned it off by clicking the "shut down" button. Ever since then, I haven't been able to turn it back on. When I push the power button on the tower, it emits a yellow/orange light for about a quarter of a second. I know for a fact that there is a sufficient power supply, due to the green light being emitted on the back of the tower. I don't know what to do, and am not economically ready to purchase a new computer. PLEASE HELP! (inspiron 545)

You could have a defective power switch on the PC case. Test this by using the reset switch as a temporary power switch. The power switch and the reset switch are the same for practical purposes except, of course, the size of the button (on most cases). If the reset switch works and is able to start the PC, then you know the power switch is defective.

A:VB6: XP Style doesn't work with User Controls

Not sure if this is what you're looking for, but to create XP-style looks to your applications add a manifest file to the directory of your executable. To do this, open notepad, and copy the following text:

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?> <assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0"> <assemblyIdentity version="" processorArchitecture="X86" name="CompanyName.ProductName.YourAppName" type="win32" /> <description>Your application description here</description> <dependency> <dependentAssembly> <assemblyIdentity type="win32" name="Microsoft.Windows.Common-Controls" version="" processorArchitecture="X86" publicKeyToken="6595b64144ccf1df" language="*" /> </dependentAssembly> </dependency> </assembly>

Save the file as your application.exe.manifest
For example, for your application called Pong, you would call the file Pong.exe.manifest

Now simply run your exe and it should be converted to XP style. I'm pretty sure this would only work with XP machines, so if you tried it on a Windows 2000 machine it wouldn't look like XP.

If this isn't what you need let me know.

The reason you can't find the G310 to buy is that Nvidia made it only available to what is known the OEM channel, basically means it can only be bought from system builders (Dell, HP, etc). Spec and build-wise the G210 and G310 are identical, so in what way does it not fit? If it is the back plate bracket that is too long the card should have come with a second shorter one (2 of them actually) like the ones shown here,

Windows will allot 50% of your ram by default, for when you need them programs. Remember, rams fastr than hard drive, and why have all that ram and not use it.

For your power supply, a nvidia 430/440 or an ati/amd 6450, maybe get away with a 6550... Seasonics are quality.

The slowdown is probably because Vista is a bit more of a beast than xp, and graphics can be a bit more hefty.

Hi there, i'm about to receive my XPS 8910 Desktop in the mail today and I have a new 8TB to add to it. I was wondering if there was an extra SATA cable inside the housing or do I have to buy a separate SATA as well as a power cable to hook up to the extra drive to the motherboard? Would a splitter work?

That, and do I have to buy extra screws to mount the new drive in place? Thanks guys!

A list of the cables and parts I would need to add the new hard drive would be greatly appreciated.

All i'm assuming is:
An extra SATA cable
A SATA power cable
or a SATA splitter?
Screws to mount the hard drive.

Am I missing anything?

A:What do I need to add an extra hard drive to my Dell XPS 8910 tower?

The unused power supply leads will be tied up near the power supply. No, we would not provide extra SATA cables. The two #6-32 X 1/4" screws will be on the hard drive cage and bracket, page 12. Before you get the 8910, you should review the 8910 Service Manual linked above.

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!

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.

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.

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.

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

I have a dell that does not read the cd-rom. In bios it reads "cd-not installed. Does that mean adding text to a file? Look at photos

A:Dell Optiplex 260

It displays "cd-rom device NOT installed". So the drive is faulty or not connected properly.

I am new to this site, and I am needing some help. I am trying to erase the hard drive on a Dell Optiplex 755 with Windows XP, and reinstall factory settings. I have already reinstalled major drivers once, but the user says that this harddrive is "buggy", and since I'm suppose to be the IT guru he wants me to do a factory reset. My two questions are this. First. Is it Ctrl F11 or F12 that I hold when starting up, and where do i go from there? Secondly. Do I need anything like killdisk or paragon disk wiper pro to fully erase harddrive?

Thanks for youtr help.

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 ?

Has anyone installed Windows 7 on a Dell Optiplex GX 280? I am trying to install and and I get as far as the initial "starting windows" where setup begins at, and I get

STOP: c000021a {Fatal System Error}

Anyone know what is wrong?

Press F8 during boot. Select Last Known Good Configuration. If this works, we will take it from there.

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 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,


A: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
