windows 8 works fine, so we can rule out; cpu,gpu,ram,power supply,motherboard
what are we left with? hard drive. looks like your HDD just bit the bullet. classic symptoms of bad sectors. battlefield died with a file error, laggy performance(disk trying to read files),long loading,weird errors like the login thing. I've seen this too many times.
To be sure, do a thorough scan on that partition,and when you find the bad sectors,time to replace the drive.
In windows,open command prompt, type chkdsk /r C: (or whatever your drive is). the /r option means repair,so it will try to repair if it finds anything.
One thing you have to do right away,backup all your stuff immediately. Bad sectors can keep developing and destroy your data.
