Speccy shows that you have switchable graphics so that clears that up, I will come back to this in due course but you need to address the lack of free storage space on your partitions first (see #3 below).
Couple of things to mention from your Speccy report.
1: You do not have an AV program installed.
2: Your power options;
Power Profile
Active power scheme: Energy Star
Hibernation: Enabled
Turn Off Monitor after: (On AC Power): 2 min
Turn Off Monitor after: (On Battery Power): 2 min
Turn Off Hard Disk after: (On AC Power): 20 min
Turn Off Hard Disk after: (On Battery Power): 10 min
Suspend after: (On AC Power): 60 min
Suspend after: (On Battery Power): 60 min
Screen saver: Enabled
While you are troubleshooting please disable or set as never each of the above options.
3: You are low on free storage space on more than one partition (3) see my canned text below;

Please note that in order to avoid data corruption and/or mechanical HDD failure for data only HDDs you must always have a minimum of 10% of the HDDs overall storage capacity available as free space and between 20 and 25% of a HDDs overall storage capacity available as free space if the OS is on it, the free space allows for information to be copied to and from the drive efficiently and it reduces the risk of the OS being overwritten/becoming corrupted by a simple task such as installing a Windows or a third party software update.
Not having the above can render a computer inoperable if the HDD concerned has the OS on it due to the MBR (Master Boot Record) becoming damaged/corrupt, please see information @ http://pcsupport.abo...sterbootrec.htm
