Hi, sorry for my newbie mistake, here is my second attempt: My PC started crashing, it then reboots itself on it's own. I'm thinking in my amazing knowledge of PC's (NOT) I might have done something to it. The PC has been upgraded recently (new harddrive, new Videocard driver, new RAM, new Processor) . But my genius self didn't do it, I had help of course. Here is the error code: BCCode : 1000007f BCP1 : 0000000D BCP2 : 00000000 BCP3 : 00000000 BCP4 : 00000000 OSVer : 5_1_2600 SP : 3_0 Product : 256_1 I attached the 5 last minidump files, can somebody take a look at it? @kimsland: I started the Daemon Tool installation, but it never finished. The crashing happened before that already, but when I did the Daemon tool installation I got a lovely blue screen also.
