I've had many blue screens since as well as screen freezes when playing games. I don't know what to do because I've sent it off to the manufacturer and they tested to see if it's hardware and they found nothing although they upgraded the 400 watt power supply to a 700 watt power supply as well as replacing my GTX 650 with a GTX 650 Ti. The GTX 650 Ti hadn't been screwed in so it had fell out of the slot, the problems were already happening so it wasn't that that has caused the issue. I've been told and I believe it's drivers that are causing the problem. It mainly points to the Nvidia drivers when it blue screens as it points to nvlddmkm.sys. I've formatted the HDD at least 3 times now and the problems always come back. Recently, before I formatted last week I couldn't use system restore so that's when I formatted. I still can't use system restore, it says it can't load a file to restore it, I also can't use the clean install option of the Nvidia installer as it says "the requested operation cannot be performed on a file with a user-mapped section open". It just freezes which is the worst part, it doesn't tell me anything about the problem, I'll upload a picture of installed programs/drivers. Please help.
