Haha. In a way. I have a HP dv4 which came from the factory with 64-bit Vista which utilized the 4GB of RAM installed. However, I "upgraded" to Windows 7 x86 and now am only able to use 2.90 GB of RAM. I used PatchPAE so that I could use all of the installed RAM. I did everything right; used an elevated instance of Command Prompt, etc. etc. I am given the option to load two "different" OS's when I boot my computer. When I try to boot the patched version, the Windows logo comes up, drivers are loaded and so on and so forth, but once that Windows logo disappears, the screen goes black for about 1-2 minutes before rebooting. The only way I've been able to use the 4GB version is by booting it in safe mode; which everything works accordingly, only it's very limited. (TY Captain Obvious) Startup repair tells me to remove removable media and reboot, but that definitely didn't work. So, anyone have any ideas? I've searched countless forums with no avail.
P.S. My normal, unpatched Win7 boots fine just like it always has.
P.S.S. I have SP1, and tried using both PatchPAE's (Non-SP1 & SP1)
