filter the data and look at the duration column what takes so long.

The rest is fast. So the group polices are the cause of the slow booting.

hm, do you use the latest firmware for the SSD? Do you run the SSD in AHCI or IDE Mode? You can also start Process Monitor, start the logging and run the xbootmgr command. After the reboot look in the ProcMon Log which action causes a long duration.

those data are µs, so it is only 1s whic his ok. hiberread="166322000" this is too long. So reading the hibernation file is too slow. So disable the hibernation file, defrag C: and enable it the file again.

read here how to overclock: http://www.tomshardware.com/reviews/sandy-bridge-overclocking-efficiency,2850.html http://news.softpedia.com/news/Intel-Sandy-Bridge-Overclocking-Potential-Explored-177765.shtml http://www.legitreviews.com/article/1501/8/ Start in small steps with the overclocking. Not all CPUs can be overclocked the same way. Overclocking means running with higher CPU clock rate which also speeds up encoding. I have no idea about SLI and if CUDA software benefits from it.

yes z68 with K CPU allows overclocking.

Intel has several Chipsets for the Intel Sandy Bridge (Codename of the 2nd Edition of the Intel i Core) CPUs. The H67 is for home users and make use of the integrated graphic of the CPU but doesn't allow overclocking. The P67 is the chipset for advanced users who want to overclock their CPU, but with the P67 you can't use the integrated GPU of the Sandy bridge CPU. The z86 combine the H67 and P67. So your Z68 based board is fine for you and you can start encoding videos

do you run the system already? In this case, don't change anything if it works.

why a Z68? Your board doesn't use the GPU from the Intel CPU and so a board with P67 is enough. Z68 combines usage of the onboard GPU inside the CPU (H67) + overclock ability of P67

yes removing the driver disables sound. And without sound, you have no issues... I have no idea. Maybe the motherboard is damaged, maybe something elase. I have no real idea

correct. Now it is 40% CPU usgae caused by the driver. Check the driver settings and enable Interrupt Moderation and all Offload options. Also try to lower the speed to 100MBit. I doubt that you have a 1GBit Internet connection.

try to capture a crash dump and upload it.

disable the battery in the device manager when using AC power. Does this fix it? Google a bit for ACPI.sys+Battc.sys results and try suggestions you find. I broke it down into Battery/ACPI and now you must try until you find a solution/workaround.

the L1C62x64.sys driver causes the high CPU usage (37%) in the NT Kernel: From what I see this is your Atheros L1c PCI-E Gigabit Ethernet Controller driver. You use version 1.0.0.36 so try to update the driver, please.

the acpi.sys is called by the BATTC.SYS (BattCWorkerThread). so check the battery. Remove it while using AC power and check if this fixes it. You can also unintall the battery from the device manager, reboot and let Windows install the battery again. This also solved high CPU usage for some users. If this doesn't fix, request a recharge of the battery. I don't know if your battery supports this. And next time, don't do illegal torrent downloads while making the trace

yes, upload the trace and send me the link.

the generated DPC_Interrupt.etl you get after you run the last command.

don't upload the kernel.etl Run the commands like I shown in the first post. I can't see which functions is the cause from the kernel.etl.

have you loaded the default BIOS setting? Have you removed the Acer tool and used the balanced power plan of Windows 7? If this doesn't fix it, create a new trace. But this time only capture 30 - 60 seconds. Otherwise the trace is very large and slow to handle with the viewer.

the sound driver is fine. The sound issues come from the ACPI driver. Have you removed the Acer Software?

Hi Sean, the trace shows the same: Total = 35412342 for module HDAudBus.sys Elapsed Time, > 0 usecs AND <= 1 usecs, 1083816, or 3.06% Elapsed Time, > 1 usecs AND <= 2 usecs, 24505101, or 69.20% Elapsed Time, > 2 usecs AND <= 4 usecs, 9688246, or 27.36% Elapsed Time, > 4 usecs AND <= 8 usecs, 52523, or 0.15% Elapsed Time, > 8 usecs AND <= 16 usecs, 4960, or 0.01% Elapsed Time, > 16 usecs AND <= 32 usecs, 75286, or 0.21% Elapsed Time, > 32 usecs AND <= 64 usecs, 2410, or 0.01% the highest spikes are between 32 and 64µs and most DPCs only take between 1 and 4µs. So the HDAudBus.sys is fine. This is not the cause: Only the ACPI driver is a bit too high: Total = 1044 for module ACPI.sys Elapsed Time, > 0 usecs AND <= 1 usecs, 0, or 0.00% Elapsed Time, > 1 usecs AND <= 2 usecs, 0, or 0.00% Elapsed Time, > 2 usecs AND <= 4 usecs, 0, or 0.00% Elapsed Time, > 4 usecs AND <= 8 usecs, 0, or 0.00% Elapsed Time, > 8 usecs AND <= 16 usecs, 503, or 48.18% Elapsed Time, > 16 usecs AND <= 32 usecs, 21, or 2.01% Elapsed Time, > 32 usecs AND <= 64 usecs, 95, or 9.10% Elapsed Time, > 64 usecs AND <= 128 usecs, 14, or 1.34% Elapsed Time, > 128 usecs AND <= 256 usecs, 65, or 6.23% Elapsed Time, > 256 usecs AND <= 512 usecs, 6, or 0.57% Elapsed Time, > 512 usecs AND <= 1024 usecs, 49, or 4.69% Elapsed Time, > 1024 usecs AND <= 2048 usecs, 262, or 25.10% Elapsed Time, > 2048 usecs AND <= 4096 usecs, 29, or 2.78% this is mostly BIOS related. So update the BIOS and which power plan do you use? Also try to stop the Acer ePower Management Software and look again if you have new issues. Does it happen when the laptop runs with Battery or if you run the laptop with normal AC power from AC power sockets?
