PC freezes at random times, all troubleshooting, diagnostics, say everything working correctly, and 0 problems, yet PC freezes. Have done registry repair, defragment, etc...but it will freeze upon startup, playing a game, random times. Sometimes runs for hours with no problem. Event error codes always the same- 10016, 7000, 1002, 1000, 1001,, ran suppose fix on these, but they just come back. Is a new hard drive, with loads of memory. Does anyone have any similar problems, and have actually fixed? And can anyone answer why all troubleshooting show PC is working correctly, when it's clearly not? Thanks for any help, suggestions.
