Hi, I bought this computer a while ago maybe 4 months ago and after a month, I started having blue screen of death :| I got like apc index mismatch. page in non paged area. so I wondered what was the problem_but i realised that this problem comes only when Im away from computer meaning goes to screen saveR..or I play game(full screen) I thought it was video card issue. SO i bought a new card GT 240..and I still get blue screen while playing games. I have attached the minidump to this thread; hopefully someone can help me. - things i have done ; f9 diagnostics and found no errors on hardware updated drivers + video card (new one installed) I have bit doubt on Norton; so any help?
