  It would be a good idea to run the System File Checker tool if you have corrupted files

  "How to use the System File Checker tool to fix the files on system missing or corrupted on Windows Vista or Windows 7"

  http://support.Microsoft.com/kb/929833

  Use the (SFC.exe) System File Checker tool to determine which file is causing the problem and then replace the file. To do this, follow these steps:

  1. Open an elevated command prompt. To do this, click Start, click principally made programs, Accessories, right-click guest, and then click run as administrator. If you are prompted for an administrator password or a confirmation, type the password, or click allow.
  2. Type the following command and press ENTER:
     sfc/scannow

     The sfc/scannow command analyzes all protected system files and replaces incorrect versions with appropriate Microsoft versions.

  If SFC detects serious flaws, you may need to perform a repair upgrade Installation or relocation complete if you don't have a Vista DVD from Microsoft.

  If you can borrow a DVD of Vista from Microsoft you save doing a reinstall full:

• OptiPlex 745 Mini-Tower - GFX card options?

  Hi all

  I own an optiplex 745 Mini-Tower and I want to install a graphics card. I read the manual and it says that its PCI Express slot is 16 x but I could not find anywhere a response on whether it is compatible PCI-E 2.0 or 3.0. This makes the choice of a quite difficult graphics card. I read somewhere that if I install a 3.0 card gfx, it would be "backward compatible" feel, he would work on a 2.0 interface (isn't that backward compatibility option depends on the entirely gfx card?) Some cards him and others not so I'm not mistaken).

  So, this is the case with this model, or it is indeed a 3.0 interface?

  Could I install a 3.0 card gfx or 2.0?

  Thank you.

  jdj9

  PCI-E 1.0 or 2.0 are very good.  PCI-E 2.1 or 3.0 may or may not be backward compatible. Some R4 R5 R9 of R7 of Sapphire cards do seem to work in older systems like the precision, etc. 490.  I used an ASUS GDDR5 PCI-E 3.0 GT740 and it worked fine in my 745.

  The problem is that the profile for the 16 x power plug changes with version 2.1 and 3.0.  In addition, Sapphire will show they don't support UEFI BIOS systems with their R series cards.

  It is also why the older variety of version 1.0 or 2.0 cards often are not seen at all on the bus 3.0 on new computers.

  The Asus EAH6450 works very well in all models of Dell, in that I have tried.

  Not compatible with USFF or Micro because they have no slots.

  The only new parameter is the secure boot must be extinguished and CSM on for some cards to post.

  ASUS EAH 6450 SILENT card fits all models of Dell who have a Slot PCI - E, meaning that it does not work with USFF due to no expansion slot. The 6450 a 2 X the number of shaders as the 5450 doesn't.

• OptiPlex 745 Ram sticks

  I got 4 sticks of memory, then my computer stopped to reach the office. I reinstalled and nothing. Then I started to remove the ram. It appears 3 sticks work very well but the 4th does not work. My question, if I want to replace this stick of memory, why online memory sellers indicate buy 2. for this computer. I only need 1 stick. This computer has a duty of memory that insists on 2 sticks? I will have to remove one ram stick works just to make room for a new stick?

  SpeedStep is quite right, and that's why sellers of memory will tell you buy RAM in pairs for an Optiplex 745.

  However, in your case, that you could buy just 1 "stick" If YOU BUY the EXACT SAME DIMM (stick), AS THE ONE THAT DIED.

  It is also sometimes possible to mix 2 DIMM RAM ('stick') which are almost the same, but just a little different, in the same channel (white or black slots) and get away with it. I do not recommend for you and it's something I usually stay away.

  So, here are your options:
  1 - Stay with your work DIMMs = 3 you have less RAM
  2. get the exact same DIMMS that one who died = RAM same as before
  3. get a pair of DIMMs either new or second-hand = change maybe, maybe not

  You have not told us if you have a minitour 745, office or SFF. You can't have a USFF because that has only 2 DIMM slots. You also do not have told us that the DIMM size, it's that you have in your machine. I guess it might be 2 GB, 1 GB or maybe 512 MB.

  Your machine is a bit old, and you can upgrade to a newer model. It doesn't have to be a new machine. You could get a 790 Optiplex opportunity or whatever... just something more recent.

  If you want to stay with the 745 and you had an of DIMMS of 1 GB on you then you could possibly spend this channel to 2 GB DIMMs. This means that you buy 2 DIMM and you would have an extra (needless) 1 GB DIMMS on you hands after the upgrade. I hope that you do not have 512 MB DIMM.

  You have options...

  Option 1 to stay with 3 DIMMs is not such a good. As a general rule, a dual channel as your motherboard will be happy with an odd number of DIMM if there is just 1 DIMMS plugged into the Board of Directors. 3 DIMMs in this kinda mobo can easily stop the mobo to boot. If yours starts with 3, then it of at least partially OK with this config and could be totally OK with it. I suppose it could be possible so that it starts and yet still ignore the 3rd DIMM. You will need to check with the OS.

  Option 2 to replace the DIMM module dead with another of the [exact] same is good enough. You can most likely get another DIMM used on eBay or Amazon or. Both have good collateral. If you receive a non-working DIMMS (unlikely) you either get your money back or you get one other DIMM, but you have to complain to the seller/eBay/Amazon to get the replacement DIMM. It may or may not be difficult to find a new exact replacement for your dead DIMM. It depends on the DIMM.

  Option 3 is a bit like option 2, except that you may be able to upgrade to 2 GB DIMM, if this isn't what you have now. New and second-hand DIMM is options in question.

  Your 745 takes 1 GB and 2 GB DDR2 DIMMS. Those who are fairly cheap these days if you buy used them. According to my experience, RAM used on eBay/Amazon is just as good as new, but YMMV. Some people are just better feel on the purchase of new parts and get a 1 year/90 days / whatever is guaranteed. Choose wisely, grasshopper.

• The use of storage local sata on Dell Optiplex 745

  I'm making Esxi update 3 using my local storage to store the VM images. I have esxi installation using boot usb according to the thread below:

  http://communities.VMware.com/message/1138818

  When I log in VI CLient, storage adapters, it shows the 2 port SATA IDE Controller (ICH8) with vmhba1 and vmhba33. But when I try to add a data store, it gives an empty list.

  In my BIOS, I put SATA to legacy and active chip virtualization, the player has a fat 32 partition. I copied the new oem.tgz in Hypervisor1.

  fdisk-l and esxcfg-vmhbadevs only list vmhba32 device which is my USB.

  I tried to find info on both devices in/proc/scsi/ata_piix and for both entries contain the following message:

  The driver does not yet support the proc fs
  vmkadapter:vmhba1

  Since then he has worked for some else with the same exact system, so it should work for me as well. What should I try next?

  I would try it with SATA Native mode.  In addition, make sure that you do not have built-in capabilities "RAID" activated - the Optiplex 745 has of an embedded controller "fake RAID", and those who do NOT work with ESX/ESXi.

  In addition, how are you on the attempt to add a data store?  You should go to Configuration-> storage and then adding using disk/LUN in the wizard.

• OptiPlex 745 sometimes freezes on the start of start page

  I recently put the hand on one occasion Optiplex 745 (CPU Intel of E6400 @2. 13 GHz, 2 GB RAM), which seems, to an almost complete lack of internal dust, were very little used.

  It works perfectly except the problem that is described in the title of the thread. When he turned, 'sometimes' (maybe 2 out of every 3 attempts), the screen freezes on the start page to start Dell with the stop bar (between Optiplex 745 and BIOS 2.6.6) progress before the end of his race.

  It seems if stop is at half way through (under the '7' in Optiplex 745) or after only 25% of his race.

  It is interesting that he stops, apparently, exactly one or the other of these two points each time.

  Immediately after, if I turn on the machine, then next turn, it will start perfectly about 95% of the time. Otherwise, I might have to stop/resume a third time so he can begin.

  While Google has found countless instances of computers to freeze while displaying the boot splash, everything I've come across seem to have problems 'permanent '. In other words, the start is just not possible. In my case, however, I can start and the machine seems to work perfectly as the occasional glitch.

  Can anyone shed light on what could happen here? And should I be worried?

  Hi Ron

  Thanks for your suggestions. Yes, I would have given more information in my first post. In fact, the form factor is LTS, the power button remains lit in green before, during and after the freeze, the diagnostic lights 1, 2 and 3 turned ("another failure has occurred") and no beeps sound. I don't know when the cmos battery has been replaced last as I have only had this machine a little over a week ago.

  However, it seems that the problem is now solved, but note that I did say that I understood why it is resolved.

  I did a lot of fiddling around trying to get this little machine works well. When I finally got in some OS (dual boot Win7 and Ubuntu) installed on the HARD drive, I had two sets of wireless keyboard/mouse hooked through dongles usb - not intentionally, but it's what happened.

  That is when I started noticing the problem described in my first post.

  As I need a keyboard and mouse to another computer, I removed the dongles (it had a single dongle for kbd and one for the mouse) and, subsequently, I have not had one instance of the problem freeze despite having started the machine at least 30 times since then.

  A test, I plugged two dongles of kbd/mouse as before all leaving the single dongle for the other connected keyboard and mouse set. In this case, the start is frozen in two of the three attempts.

  In order to have both sets keyboard and mouse attached seems to be the problem.

  But why? I'm puzzled.

• Dell optiplex 745 with Windows 7 Pro

  I just bought a Dell Optiplex 745 refurbished with Windows 7 Pro.  It came with a HP Windows 7 Pro re install the disc and when I'm asked them thereon, they stated that a re HP install disk is identical to a Dell disk.  Is this true and if not what problems it will create if I have to re install Windows 7.

  They are the two Windows 7, one that said you is accurate, but there are also significant differences.  Dell Media is intended to be installed on a Dell computer and activate automatically, without the need for manual entry of the product key.  HP is designed to do the same... on a HP machine.  There is a good chance that he would not accept the Dell product key either... even if she have installed successfully.  In addition, most of the OEM media even install on other than a machine correspondent (HP discs usually install on Dell, not vice versa).

• Drivers for Dell OEM 7570 on Optiplex 745

  So, I caught on the Bay, a video card OEM Dell 7570, which was a work of a XPS 8500 sweater, and I'll like to stick it in an optiplex 745 as an upgrade of a radeon 4650.  Tried to install it and not go.  I only get the basic windows vga (800 x 600 with 32-bit color) adapter function, when I want a 1080 p configuration (my optiplex 745 now works as a htpc), but at least I know that the card is not fried.

  I also tried to install catalyst 13.1, but it does not work (I had uninstalled the prior installation of catalyst with the old drivers of HD 4000 series and also followed that upward with a wipe the previous drivers with driver sweeper befor trying variations of the catalyst)

  Apparently this particular cards OEM cannot use the ordinary AMD drivers; and cannot use the drivers from Dell.  I even tried to use the 8500 XPS drivers who were for this card (once again, with an uninstall of previous catalysts and a wipe of driver before you install the drivers for the 8500 XPS for dell OEM 7570), but that didn't work.  I suspect that it is because my optiplex 745 OS is Windows Vista Business 32 bit and to Win 8 64 bit dell OEM drivers.

  Any suggestions on how to proceed?  Is there a Vista 32-bit driver for Dell OEM radeon graphic card 7570?  Should I try to install 8 64-bit Windows and then try the OEM drivers?  Or tried the drop in this map, a race of fools?

  Reflections and suggestions would be appreciated.

• Need a video card compatible for Dell Optiplex 745 (SFF) - help, please!

  I have a Dell Optiplex 745 SFF. The details of the standard can be found here: http://www.dell.com/downloads/global/products/optix/en/opti_745techspecs.pdf

  (even once, look at the MFS)

  I want to get the best possible video card for this PC that I can find, and I was hoping someone could help me with my options. I am aware of my options are limited, but I'd like to work with what I have here. Thanks much for any help.

  Sapphire 7750 is the best low profile card I know. There is no need of current auxiliary and is compatible with your power supply.

  SA makes a 7750 as well, but it requires more space and I don't know if it is compatible with your frame.
