When adding 1 Gb sticks of memory, Windows won't boot

I just bought two (2) 2 Gb sticks of memory (Crucial) and installed them in the two "white" slots, leaving the "black" slots empty.  When I run the machine with just the new memory (4 Gb total) Windows 7 comes up just fine.  When I add the two 1 Gb sticks to the 2 vacant slots, Windows 7 will not come up (gives me the choice of starting in safe mode, etc.

Why?

Try them offset. 2GB and a 1GB in one bay and the same for the other bay.
It's possible it needs the same amount in each bay.

KennyBoy5:  by "bay" do you mean the "white" and the "black" slots next to each other make one bay?  If so, I put the 2 Gb stick in the 'white" slot and the 1 Gb stick in the "black' slot... Windows would not boot...

tomago:  the 1 Gb sticks say: 1024 Mb PC5400 DDR2 667 Mhz and the 2 Gb sticks say: Max Bandwith PC2-5300 (333 Mhz)

Yes sorry that's what I meant by bay. So you have a white/black slot for each bay. When you put the 2GB & 1GB in the one bay, did you also load up bay 2 with the same configuration? Or just the one bay only? What happens when you just load up the first bay with the two 1GB sticks and leave the 2GB sticks out does it boot?

Also what kind of computer/motherboard is it so I can lookup the configuration.

Thanks

So they memory is all the same type (PC5400 and PC2-5300 are the same thing).  Have you tried putting 1 of the 2gb and 1 of the 1gb chips in the white slots and 1 of the 2gb and 1 of the 1gb in the black slots?

Also, did you try just booting with the 1gb chips again?  It's possible one of the 1gb was damaged during the upgrade so when you're putting it back in it's not allowing the machine to boot.

KB5: yes, I loaded the second bay so the configurations were identical.  I will have to shut the machine down to reload the 1 Gb sticks.  Will respond to both of you when I do it.  Motherboard is a NVida 680iLT.

tomago: going to boot w/ 1 Gb sticks now...

two 1 Gb sticks in one bay: apparently Windows 7 has a hard time booting... not sure it recognized both sticks.  one 1 Gb stick in each bay boots, but slowly (slower than before).  Am going to put the two sticks of 2 GB memory back, one in each bay.

10-4. Sounds like it no likey those 1GB sticks. I take it the 1GB sticks are older ram from another system?

KB5: no, they were the original memory; I needed to upgrade because of VS 2010 (a real hog!).

I put the 2 Gb memory in, and now the boot is taking forever (currently looking for DHCP).  Did I farkel something up in this process?

From the MB manual:

"One DIMM: Install into slot 0. You can install the DIMM into any slot,
however, slot 0 is preferred.
Two DIMMs: Install into either slots 0 and 1 or 2 and 3. The idea is to not
have the DIMMs in adjacent slots.
Four DIMMS: Install into slots 0, 1, 2, and 3."

The DIMM #s (from left white slot) go 0, 2, 1, 3

So booting just 2 chips, they should both been in white like you had them.  When booting all 4, it should be 2gbs in white and 1gbs in black.

With the 2gbs in the proper slots, try just booting after adding a single 1gb.  If that's okay, replace the 1gb with the other one to see if it still boots.

Sounds like its trying to do a network boot. If you go into the BIOS does it see the hard drive?

Do you have 32 bit or 64 bit Windows 7?

DHCP search is network configuration in Windows and not BIOS related.

current memory config is 4 Gb, recognized and has an OK next to it in boot sequence...

Windows 7, 64-bit

I don't understand why it 's doing the DHCP thingie, and how do I fix the Windows 7 network config problem?

I'm wondering if you've knocked the cable on the hard drive inside while reseating ram. That would force it to do a network boot possibly

Searching for a dhcp server in a PXE boot is most certainly BIOS related. If it's in the boot sequence then for sure it's going to look for it.
