I have configured my PC about 6 months ago. After one month it started showing BSOD frequently. Initially I thought it was a software problem. My pc was working very slow and was keeping crashing all the way. When I use to browse internet it was showing failure as it was crashing. I have 4 cores installed in my pc. I found on the web that I should use one core in my CPU to work well instead of four. I changed it to 1 core it was working fine but when I changed it 4 cores the problem started again. Can anyone help me?? Any suggestions will be appreciated. Thanks in advance.
