20 Most Recent Dell Precision T3400 375W 32bit Computer Workstation PC Desktop Questions & Answers

a lot of info for what sounded like a simple question. i first thought that maybe you did not have the CD wiring connected properly? if the pc powers on, then that would be my first guess, check the wires you hooked up to the cd player. then 'if ' you have problems with the install of the OS, can the cd player read DVDs? software can be on dvd not cd so the cd player would not work. if you can get into dos, or select PF2 or PF12 on boot to see where your cd is in the boot sequence or even listed. more detail on what you have tried is required when trying to solve an issue. Many of you do not give enough info on what has already transpired in trying a solution yourself. good luck

The memory specification for your workstation is here:

You can remove the 1GB modules and replace with 2*2GB modules to give 4GB and you are correct in that you will need to use a 64-bit operating system to fully utilise 4GB or more.

Hope this helps,

Your CD drive or DVD drive is missing or not recognized by Windows or other programs, so you cannot play or access a CD or DVD. This issue might have occurred after you installed, uninstalled, or updated a program

Click Start, click My Computer, and then see whether the drive is listed.
Is the drive listed? loadTOCNode(2, 'moreinformation');
If the drive is listed, try to play or access a CD or DVD.
If you can play or access a CD or DVD, you are finished with this article.

If you cannot play or access a CD or DVD, you may have to reinstall some programs. Some programs might not be able to use your CD or DVD drive until you reinstall those programs. If the problem occurs again when you install or uninstall those programs, contact the manufacturer of the program to see if an update is available that solves the problem. Some examples of programs that might be affected are:
  • iTunes software by Apple
  • Nero software by Nero Inc
  • Roxio Creator software by Sonic Solutions
  • Zune software by Microsoft
After reinstalling your programs, if you can play or access a CD or DVD, you are finished with this article.

If you still cannot play or access a CD or DVD,

If the drive is not listed, remove and reinstall the existing drivers.

Turn the machine off
Open the case
Look to see if there are IDE connector (Wide Flat cable with a connector usually grey)
If this is not present look for a SATA connector usually a small red or blue wire similar to a cat5e network cable
Scew your HDD in place in the rack connect the cable either IDE or SATA
If you have an IDE drive look for a 4 pin female connector from the power supply
If you have a SATA drive look for the connector from the power supply
Once all is connected then reboot you computer typically your bios should auto detect it.

Let me know what happens from here

this 2007 year PC OLD, has many limits (CORE 2 is one)
is this windows 10? 64bit> I bet not its CORE 2 old)
I came with VISTA if MS loaded OS, or XP or RedHat Linux?
what boot menu are you talking about.? F12?
wild guess me, VISTA OS: (now zero support)

in windows, we have disk manager, do all devices show up now?
this is first, if not here, explorer can not work.
lets do the correct order:
1: bios sees my media. (good)
2: then in device manager, it sees them, if not drivers bad.
3: then Diskmanager sees the devices, and must have drive letter or next. if letters missing right click device and add one.
4: explorer (This PC) fails to find it. if above fails sure.

easy as 1,2,3,4 order, matters.

can't see CD does that mean a disk or the whole drive?
cant See HDD, is this HDD0 ,1,2, 3 or?
how many HDD do you have, and are there SSD drives there
and last what SATA ports are you using, some are limited.

here is your DELL.com support page, (12 years later still here)

what HDD fails,
does the PC boot at all? my wild guess NO.
what OS
what OS do you want to run, that be first thing to ask on any 2007 old PC, as Windows 10 will fail here. I Bet. for sure 64bit.

If not data on the flash drive I suggest try reformatting the drive to remove any malware

Many Dell can be a bit funny about exactly what RAM they will accept == check what other owners say on the Dell website user forums ..

Dell Precision... | Answered on Mar 30, 2016

At power-on, use F12 (or F8) and select 'Repair' ... DO NOT let it 'reformat' your drive or you will loose everything ..

If that fails, you may have to choose 'Factory Restore', but this will re-install Windows and you will LOOSE EVERYTHING !!

SO == if you have another PC, I suggest move your disk drive to that other PC and copy off all your photos/music/videoa etc you don't want to loose before doinbg a Factory Restore ..

Windows 10 is new and still in testing phase, new patches are released to fix bugs almost everyday. try running an update, make sure your hardware was compatible and the OS is installed properly, you do have the option to roll back if you want to.
