Is your pc able to POST now w either ram stick in DIMM2, leaving DIMM1 empty?

are you sure you rewire the front panel connectors appropriately in new case in order to switch on power to motherboard?

Question: Is your pc able to POST now w either ram stick in DIMM2, leaving DIMM1 empty?
My response: Yes but nothing goes to DELL post logo if anything is in DIMM1.

Please as I do not want to buy/use only 1 DIMM slot as not only is that ridiculous, but I am on a very cheap budget.

Thanks,
Henry

I forgot to mention, yes I did rewire everything 100% correctly and the front USBs on the new case work like a charm (tested when only DIMM2 was active with ram).

Please reply soon,
Henry.

You have verified motherboard, DIMM slot#2, both memory sticks work. Only DIMM 1 stops Dell logo on screen which means whenever you put any good ram in DIMM1, bios can not pass a basic firmware test on DIMM1.  No POST for DIMM1 unless it is empty.  There is almost nothing you could do to fix a faulty DIMM slot. It does not look like a bios error.  You have already tried to clean DIMM1. If there is a short circuit in the slot it may be beyond your ability to correct that.

if it is a bad dim slot you could try heating it with a hair dyer / heat gun. ive seen it done but never tried myself. just a thought... GL    z 

• The one dimm slot could be bad. Also, are you sure you wired it correctly? Dell front io are proprietary and you need a header adapter that can be found on eBay.
