I had an old Optiplex 745 that had been refurbished and started acting up.  I decided to replace all the RAM and did so with what suppliers and Dell states is acceptable.  2 kits of 2GB (2x1GB) 1GB DDR2-800 PC2-6400 Non-ECC unbuffered 240 Pin 1.8V CL=6 Memory 128x8.

 

Now the system goes to immediate BSOD.

 

And no, I don't know what I am doing.  I did however, make sure the cards were all seated properly.

 

The error I get is 0x0000020 (0x001dd3d0 0x00000000)

 

As I said this machine has been a problem child.  I was trying to reload with Win 7 professional 64 bit which is what was on it.

 

Any ideas?

 

Thanks in advance.  :)

Can you boot into Safe Mode?

 

If you are unfamiliar with Safe Mode I've posted instructions to boot into Safe Mode.

 

With the computer shut off press the start button and immediately start tapping the F8 key, continue to do this until you see an image similar to the one below or you see the black screen.

If you get to this page use the up or down key to navigate to Safe Mode, then press Enter to select this option.

 

Let us know what happens.

 

Do you have the installation disk that came with this computer?


Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

I have not gotten that far to try as I get the BSOD first.  But, I have cleared the CMOS and haven't tried it.  I'll give it a whirl.  I don't have the installations disk that came with it, but do have bootable Win 7 installation disk.

 

Let me give it a try and I'll post back.

 

Thank you.

I would also check your BIOs to see if it shows the full ram installed.

Sorry I haven't replied to whether BIOS recognizes the RAM.  Got an emergency job where someone "called the number on the screen" and let them take control over their XP system.  I'm trying to 'fix' that one now.  Hopefully will be able to get back to the original Optiplex 745 shortly.
