Hi there, I'm new to this forum and since I've seen couples of people who had solved their PC problems, I decided to post my problem here. Just 4 days ago, I faced a problem when my computer occasionally crashes and enter a blue screen. Note that this PC is only 14 days-old and comes as a set (I didn't buy any hardwares separately). It generates the code as the topic says above: 0x000000C2 ( 0x00000007, 0x00000CD4, 0x000004C0, 0xE12A9A80 ) and says something like BAD_POOL_CALLER Can anyone tell me what's wrong with my PC? Thanks! EDIT: Just so you all know, I'm facing problems such as program crashes and sometimes failing to install softwares/games. When I play games, they hang. And during some installations, they give me some message containing "CRC Error". Browsing sites with Firefox sometimes crashes as well. Please help. Your help is very much appreciated. Thank you. EDIT 2: After seeing lots of posts, I found out that it's necessary to post minidumps. Here are the files required. Please help to investigate the problem. Thanks!
