So I can use any of the 2GB sticks in slot one or two, but I can't use both (memory is Crucial XMS2 TWIN2X4096-6400C5C, DDR2-800).
The moment I start trying to use both, Windows 7 will start giving me "Windows Explorer has crashed" app errors for explorer.exe. Ran memtest on each stick and had no errors. Then ran each separately in slot 1 and then in slot 2. No problems.
This is a fresh install of Windows 7 on a clean drive and the error has occured since first boot.
The only things I've loaded are the motherboard's drivers
(motherboard is the MSI 785GTM-E45 with stock settings), Nvidia drivers for the 9800GTX+, Nero 9, and the onboard Realtek HD Audio. No matter what, the computer will run just fine on 2GB, but not 4GB. Think any of these could have an issue with 4GB?
Using these variables, I've ruled out the following potential issues:
-Bad RAM (did Memtest86 off of bootable disc)
-Bad mobo RAM slots (tested RAM, ran good RAM sticks in both slots individually)
conflict (could still be an issue I suppose)
-Please do not tell me it's a context menu issue because it is not (fresh install, nothing added)
-BIOS shouldn't be an issue since the computer runs with 4GB when Windows 7 is not running. The issue is in Windows 7 ONLY (checked, newest)
Thanks in advance.
