The BIOS might be fixed configured... IE: when Gateway built the computer, they set the BIOS to identify the chips they put it. Generally, whenever you do a serious hardware change of this nature, you want to go into BIOS first and see if it detects things properly.

In your case, I think the bios still thinks you have something else. First thing you might want to try is see if you can re-seat the memory, blow out any possible dust as well.

Reboot the system, go into the bios and check to see that it SEES 8 gigs of ram. If it does, then check Windows when you get in there and see if it sees the same.
What do you mean "re-seat"? like take it out and put it back in? I dont know why would the manufacturer advertise that it is expandable up to 8 gigs and then they put a bios that wouldnt recognize it, that would be the pinnacle for gateway!
Depending on certain builds, they might have had minor settings. As for expandable, it is. However, what most normal users don't realize is you just do go 'buy ram and stick it in'. You have to buy specific ram for a specific system. In some cases, you may have to go into the BIOS and make some minor checks or changes to assure that it recognizes the change in the system. Dells normally do a BIOS alert warning stating exactly that for that reason, to make sure that the user is aware a change has been made and to check bios in case this was not the case.

As for re-seating, yes, take them out, used compressed air or something that will blow a puff of air over the ram slots and over the ram, do not touch the ram contacts directly. Then put them back in. Sometimes with memory upgrades, especially in systems that have been in operation long enough for the system to have dust within, can have contacts blocked by dust, which could also account for issues.

I would recommend just pulling the ram out... Do a light clean and put it in, go back into the bios and make sure it SEES 8 gigs.
