Okay, so 2 weeks ago working on my DELL Inspiron 1545 laptop... my browser (Firefox) was frequently NOT RESPONDING, then no icons on my desktop nor start menu would respond. Then after 2 days of hard SHUTDOWNS, the computer would do a false boot (black screen with a mouse only). I rebooted the OS. The last two weeks have been fine until the same thing happened. Have not rebooted again, but it boots when it wants to and works fine sometimes but will false boot often. The only way out is to remove the battery and remove the AC adapter cord. And it false boots again and again and again. Then it will work. Had the thing for 1 1/2 years. It is too early for a bad hard drive. ALL FILES BACKED UP ALREADY. HELP ME FIX IT?
