Being confused over this, I contacted the manufacturer of my G-card (an ATI HD Radeon 6970) explaining what just happened and they told me that faulty memory is most likely the problem so I ran a 4 hour long memory diagnostic with Memtest which they linked me and It came up with zero errors. I contacted them again for more things to diagnos and they suggested checking my HDD's which I also did and came up blank.
In the midst of this, I was also experiencing other errors such as, "bootmgr is missing", failed computer bootups, failures to launching windows, repeated beepings on startup indicating that I have a loose cord without actually having a lose coord and many other things even with my old g-card installed.
I have thoroughly checked for any kinds of malware without result and have experienced zero slowdowns before the incident having all my hardware be brand new. Ideas?
Update: It recently wouldn't start the POST until i disconnected external drivers and when I did, It hanged on windows starting followed by running a failed windows repair which told me something related to BadDriver, localeid 1033
Update 2: Been running on my old graphics card stable for over 10-20 hours straight now, thinking of plugging the new one back in.
