Hi, i have recently bought a new monitor for my pc and plugged it up and turned her on. I get "bootmgr not found, ctrl/alt/del to restart" I have tried to boot off the windows7 disc i have but it gets to the desktop background and freezes. The computer worked fine before (bout 2 months ago) until my monitor blew. I am thinkin it isnt the monitor and have read about some things.. RAID? others mention RAM defects? I am a novice but do understand how to access BIOS/setup. Shoould i try rebooting with one RAM stick in at a time to eliminate this as a cause? how can I format the drives and reinstal from setup? I dont have anything on the computer that is important as it was a fresh install when i used it last. Help much appreciated!
