Currently installing on a Dell Dimension E521 3GB RAM Onboard nVidia graphics card Removed all expansion cards (firewire / wireless) Clear out 160GB drive Create new partition Windows 7 install says it needs to make a 200mb partition for system files Creates that and then a 150+ GB partition Copies files Reboots once Gets to completing installation portion Screen eventually goes black I can see a 1 pixel line at the top of the screen The PC is not locked up I can move to mouse up to the top and see the tip of the mouse cursor Try rebooting and going into safe mode says installation cannot be completed in safe mode Let it sit for about 3 hours on the blank screen Nothing Any ideas? An upgrade from Vista works just fine. I am thinking this may be a video card issue. I am going to try with an expansion video card later today. Just wondering if anyone has any thoughts.
