.. after 15 minutes of hanging in that weird startup screen, considering whether to hard reboot or not, it went into start repair (still there now)...
To make a long story short, I suspected something wrong with my hard drive due to a software giving me an i/o error, after some research (I am not knowledgable when it comes to computers), I ran chkdsk, when I woke up it was still running as it should be (in the process of 'replacing bad clusters' for certain files... so there was something wrong alright) and was at 28%.
After leaving my computer for ten minutes, I found my computer had gone to a black screen and seeing as I was reluctant to do a hard reboot, I waited it out and it moved to a windows safe mode startup screen... but only the big cursor and standard background was present, nothing else .
After ten minutes it went to startup repair, which has been running for the past half hour.
What has happened during the ten minutes I was away and chkdsk was still only at 28%, why did the subsequent events unfold as they did? What can I do now??
