Hello everyone, Yesterday I experienced 3 restarts in a short space of time. I took the minidump files onto a memory stick before reverting to a manually created restore point (created on 30th May). I also have a restore point just before a windows update was installed on 24th and 25th May but havent gone there yet. Everything seemed fine when I done this at 11pm last night and used it for a bit to check if it happened again. However, this morning after loading fine and using for a short time the it went into screensaver and then sleep mode whilst I was busy. Unfortunately, It seems like it has restarted itself again. PC Specs: (Anything else needed just say) HP p6740uk [TABLE] [/TABLE] AMD Athlon II x4 640 (3.0 GHz) AMD 760 G chipset 4GB DDR3 memory 1TB SATA HDD NVidia GeForce 405 (1GB) After using some online and downloadable .DMP analysers I saw things like VISTA_DRIVER_FAULT and ntoskrnl.exe problems. But I have no idea what to do now. I have a feeling it is video card driver issue, windows update effects or a damaged PSU (happened before on different PC). I have attatched the dmp files from yesterday (dmp_files_7) and today (dmp_files) and the CPU-Z images. Any help will be greatly appreciated.
