Get 2 random things happening - Randomly the screen will pop blue with windows has encountered and error and needs to restart. Second - Screen goes black. PC seems like its going into limp mode and have to restart to get video feed.
remove ram and the cmos battery in motherboard....do all this while pc is off. after 15 minutes or so place them back in and try booting pc. if this doesnt work turn off pc and remove one ram stick if you have 2....and remove the graphic card too and then attach the video cable to ur motherboard which was in the graphic card....then try booting ur pc in safe mode or so. if u somehow manage to boot up and get into ur windows......quickly run msconfig and under startup tab unclick every single shit there is and turn off antivirus. also try switching ram sticks when pc is off. and once it boots up fine like last time...... defragment your hard drive or wherever ur windows is installed to avoid losing the windows forever
