Um,I have a question, earlier yesterday, after my session crashed, I attempt to run my laptop so I could continue my session. During my attempt, after the windows logo flash, the system in't seem to work for it only shows black screen. I experienced this several times, the I noticed, once, it prompted me to choose to run in normal mode or in safe mode. I chose safe mode, then the system seemed to run because it ran during that mode. Then I shut it down, and hoped to run in the normal mode but it didn't. So, I tried the f2 then f8 mode. Its I ran the diagnostic and asked me to system restore.
