After installing Windows 8 Pro(x86), and installed drivers, my PC frequently doesn't turn on after sleep/hibernate. After some days, the PC doesn't turn on even after shutdown rarely and if it starts, it worked well. For months it was like that. But from march 2013, it doesn't turn on itself. If I remove RAM and put it or use reset and start buttons/restart button, it'll turn on. Now for few weeks, PC doesn't turn on after doing the above for single time. After doing for 5-10 times, PC will boot, but after sometime it'll be working normal or getting hanged and getting BSOD error DPC_WATCHDOG_VIOLATION frequently. I tried removing drivers except Nvidia Display Driver[Latest], but in vain. I also tried Automatic Repair, it says it couldn't fix it and then gets hanged in windows 8 boot logo. I've attached 2 recent Minidumps[in Zip files]. Please help!
