4GB RAM (2×2) and OS is Windows 7 64bits
I recently added a third RAM of size 2GB into my Dell Optiplex GX620. The original specs had 4GB RAM (2×2) and OS is Windows 7 64bits. Bios check had detected correct installation of the additional RAM.
However, I couldn't get the Windows to run and it restarts itself right after the Windows Start-up screen. All three RAMs are of the same brand and size, specifically Kingston KVR800D2N6/2G. I'm really confused why the BIOS can detect them as okay and working but my Windows wouldn't start up.
I suspect this is with the operating system as it would seem to work fine when I remove the third RAM. Do you suggest I just switch to Ubuntu instead? Can anybody advise how to solve this problem?
Great thanks for the help!
