HP dc7700 desktop ram slot one (black) not recognizing ram

I have a HP DC7700 desktop computer, with 4 ram slots. If ram is placed in first slot (It is a black slot from the factory) it is not recognized and the machine will not boot up with the slot filled. I can place 1 gig ram in the other 3 slots, and all are recognized, but machine runs very slowly, even though it is a 3.4 gig processor.

HP says ram must be placed in the first black slot, but it will not recognize same if put there and the machine fails to boot up even though the other 3 gig of ram is recognized when the first slot is not filled.

Could this slot be bad? If so, what are the recommendations from you concerning replacing this slot?

If this slot is replaced, would it be replacable with a normal slot as is the other slots?

Help! ! ! ! !

Couple of questions for you;
Will the system boot when there is only a single stick of Ram placed in slot 1?
Is the Ram all of the same brand and specification as recommended for the MB?

Could this slot be bad? If so, what are the recommendations from you concerning replacing this slot?

It could be bad but it would most likely be less expensive to replace the MB as opposed to the slot.

If this slot is replaced, would it be replacable with a normal slot as is the other slots?

See above answer.

All the ram is the same make and model numberas specified for this computer

If only one stick is placed in the slot, the machine will not boot up at all.

All 3 ram sticks are recognized in the other three slots.

But when in other slots, the machine moves as if it is about 750 megabytes instead of 3 gig.

Hope that helps.

Thanks for the additional info :thumbsup:
Have you checked in the Device Manager for any yellow ! marks and possibly against the chipset.
Try restoring the MBs default settings in the BIOS, if this does not work try removing the CR2032 battery on the MB for a few moments and then replace it, upon first boot you will need to go into the BIOS and reset the time and date save (F10) and then Y to accept the changes.
Let us know how you get on.
