Hi I wanted to mention this HPET issue I solved in hopes that it helps someone else out. My PC, listed in my profile, has the High Precision Event Timer feature on the Gigbyte mobo. For months now I was trying to figure out what was causing Win8 to lock up periodically. I tried 64-bit/32-bit modes both seemed buggy. I was able to narrow it down to Flash, Shockwave, HTML5 YouTube player; Silverlight player. whenever I would install those and use them at some point the system would lock up for about 5 min. then resume only to freeze again later on. Almost thought the problem was my GPU or maybe I overclocked the CPU to much. I had no issues playing games or using other programs. When I was using Win8 DP I had no issues with HPET. After disabling HPET all my system freezing stopped. Now I can use Chrome and Netflix and adobe stuff without any issues. Does anyone know why those handful of plug-ins would react to HPET and lock up the system?
