How does the lower front bezel (or faceplate) get removed for painting on a 755 mini tower? I don't want to break the tabs. I painted it once, but masking everything and some of the interior was time consuming.Teardown videos on YouTube don't show lower front grill removal. May be somebody could do

Is it true that this processor will work in socket type LGA775, an Optiplex 755? Please see screengrabs.  I couldn't copy & paste.        

My 755 MT with Win7 and A22 BIOS won't acknowledge my smartphone in any way. Phone battery doesn't even show as charging.  USB ports work fine for everything else.  Is it a driver that's needed and where do I find it? If I Google it, too many unfamiliar sites want to download other stuff

I have a Dell Optiplex 755 MT with A10 BIOS. All I wanted was Win7 on one HDD and XP on the other.  While XP is old or ancient to some or many, I liked it's WMP (Windows Media Player) 9 and thumbnail prints for photos files instead of sideways view.  WMP 9 isn't available separate. In WMP

Does a Dell 755 have cpu socket type LGA 775 and sata II for system wiring? I couldn't verify elsewhere. I'm hoping a Dell user, 755 user, or etc., would know. I've seen the forums asking about processors. Refurb place I bought my 755 from doesn't know. I'm new here - What's the difference bet

This might be an easy one, but I couldn't find an answer. Dell says 7th Gen CPU only supports 2400Mhz RAM. Intel says their i5-7500 supports both 2133Mhz and 2400Mhz. I have both on the way, a Precision 3620 and an i5-7500. Is what Dell says a Dell limitation, or does the the i5-7500 support bot

Can Win7 32-bit power USB 3.0? Do I have to use a USB 3.0 card in the PCI-E x1 slot in the back or can it be front mounted and plugged into the floppy drive connector? I didn't see a reference in the Tech Guide as to how many pins the floppy drive connector is.  Google said 34 pins, so I bet

I recently reloaded my PC. The CD for the CSR Harmony 4.0 driver got scratched and doesn't work.  CD came with Wavlink Bluetooth dongle I bought in Dec. 2018. I've been trying to work with Wavlink on this.  They keep sending me links from other sites that don't work.  I can't just k

My Optiplex 755 MT has an E8400 CPU. Can it be upgraded to the quad Q9650?  I checked my pdf manual, but E8400 isn't listed in it either.  I also checked other forums herein, but I didn't find one mentioning Q9650.  It has the same LGA 775 socket type.

I installed Photo Explosion 4.0. It wanted .net framework downloaded to work properly.  I don't remember the # that preceded .net, if it was 3 or 4. If my PC is in sleep mode, it turns on by itself, always in the midde of the night with a blank screen.  I can hit any button and I get the

There's been many posts asking about upgrading CPU's to meet Windows 11 requirements. First, be sure your Optiplex model is in the Dell Windows 11 validated list. Second, Google search the Tech Guide and/or Specifications Sheet for your particular model. There you'll find the compatible list of CPU'

When choosing a Windows version, like Pro, Home, 32-bit or 64-bit, when loading from a bootable flash drive made on the Microsoft site, it will ask which version you want to load. I've done my share of reloads, and when making the ISO, you'll get:

Hi @DELL-Alasdair R, Is there way it can be posted and easy to see for people to remember the size of their computer when posting?  It's been a common problem and questions can get answered faster.  I'm hoping for it to be easy to see before clicking or tapping "post a question." Thanks,

Hi @Tesla1856, @fireberd, @JOcean, If you're interested, and I'm sure you're busy with the forums you normally do, but not enough people have been answering the threads here. I wasn't sure how else to go about it. Thanks, bradthetechnut

Anybody need Energizer 2032 batteries? Today (12-4-22) they're $1.99 for a 2-pack on Amazon.   

I wanted to post that I recently upgraded from an Intel Core 2 Duo 3.0 GHz to an Intel Core 2 Quad Q9650 3.0 GHz. It went smoothly and I didn't have to reload Windows 7. Only 2 catches: I have to move my Playlists back into Windows Media Player. WMP lost them. If I want media files to back up a

If this shows as one big pgh., it shouldn't. I also edited in desktop mode (from my phone).  It shows as normal if I'm signed out.   Win10 install went smooth (around 10min.) once I finally had it going.  Must partition to GPT, not MBR.  Once I corrected that, Win10

To reset BIOS on my Precision 3620, I can't find the RTCRST jumper pins. Is it CMCLR as seen in the bottom middle of the photo? Please pardon if this question is too easy.  Everything I dug for told me "RTCRST."  I'm newer to the 3620 and don't want to mess with things I don't know about.

Hi, I'll be installing Win10 from DVD. I plan to keep Win7 on the same HDD.  At one time I also had Vista on it to take a look at.  No problems.  Selecting OS would appear at startup.  Will that work the same with installing Win10? Many posts mention BIOS, UEFI, etc.  In

Hi @Marwen4ever , I haven't been able to reply to your thread, nVidia Geforce GTX 1650 is not working on Dell precision 3620. Threads before migration to the new site currently have the "reply" box missing. I think your GTX 1650 might be defective.  Did you buy it new, refurb, or used? O
