Precision 470 Restart Problem
I recently purchased a refurbished Dell Precision 470.
The badge shows Windows XP but the refurbishers installed Windows 7 Professional 64 bit.
They also installed a Nvidia Quadro FX3400 - 256 MB GDDR3 - Dual DVI Output graphics card. At startup there was a warning message that the card was not receiving enough power. It transpired that the card did not have a PCI Express power cable attached. One was sent to me & I fitted it. The warning message no longer displayed.
The problem is that when restarting the machine it goes off; the diagnostic lights A & C are green & B & D are yellow. The manual states that this shows a memory problem.
Holding down the power button to turn the pc off then pressing it to turn the pc on results in the same diagnostic lights.
If I turn off the pc again & then wait for a minute or two then press the power button the pc starts OK.
This is a nuisance & I would like advice.
Thanking all responders in advance,
Allan.

Thankyou for your advice & please excuse the time taken for me to reply; I had been waiting for the seller of the PC to respond.
I was about to test the memory as advised but when I tried both the start & the restart processes the good news is that they are now working fine. Another of the mysteries of PC's :-).
Fingers crossed all will be OK now but if the problem reoccurs I will follow your advice,
Kind regards,
Allan.

Take out all ram and test one stick at a time. If all the ram tests fine one stick at a time the issue is that the ram is either not dual channel compatible OR its too slow for the processor. After one ram must be installed in pairs. NOT 1 2 3 4 in the slots its 1 3 then 2 4.
