Hi, Since a week I have been experiencing BSOD randomly and also experiencing system freezes with the cpu usage hitting 100%. Even while I am trying to just delete a file I have experienced BSOD...!!!! Don't know whats happening. Even my Kaspersky antivirus is acting weirdly because earlier I could smoothly perform scans but yesterday when I was trying to scan my laptop it was not smooth as the scan was getting stuck at some point not the same point every time because restarted a couple of times when it was getting stuck.But I did complete a few scans in Safe Mode so I am confident I am not infected with a Virus. Do I need to go into the background of the problems with my laptop ? Because 3 months back I changed my motherboard because of the ATI card failure and went from DDR2 to DDR3 motherboard even back then I used to get BSOD but with atisys. error. But this time its different. Thank you for support My CPU-Z info.
