Cheers for all the suggestions, it is much appreciated.
Just wondering, could this problem be related to a hardware issue?
Such as bad sectors on my HDD or possibly a lack of memory upon startup?
Also, I've now noticed the message depicted in the attachment sometimes appears in the bottom right corner of my desktop.
Kind regards,
Koray
UPDATE: I scanned my HDD anyways and ran a memory diagnostics. They both reported everything to be working correctly.
