System crash for a few days, kernel power id 41

I have Dell Inspiron N5110, core i5 2430m, 6gb RAM, nVidia Gt-525m and installed Windows 7 64 bit. System crash, and boot screen ask me to choose safe mode or start windows normally, nothing else. In Event Viewer critical error was logged, Kernel power id 41. I have formatted windows and install again with sp1 but nothing is changed. Can anybody know what is a problem?

AVG is known to be a cause of problems on Windows 7 systems. Suggest that you uninstall it. Download the correct AVG Remover for your system (32 or 64 bit).
If you have AVG ID protection installed, download the AVGID Protection Remover from the above link as well (it wouldn't hurt to download and run it anyway). Download BSOD friendly Microsoft Security Essentials as AVG's replacement.
Uninstall AVG through the Control Panel. Re-boot to Safe Mode and run the AVG Removal tool(s). Re-boot to normal mode and install MSE. Make sure your Windows firewall is enabled!

The dtsoftbus01.sys driver has been known to cause problems on some Windows 7 systems. This belongs to Daemon Tools Light. I suggest uninstalling Daemon Tools.

Also go into your bios and change the rams Command Rate from 1T to 2T

But I don't have that option to change RAM parameter in bios. I will try to uninstall AVG. What program like Daemon you will recommend to me? Thank you for advice, I think that this will solve my problem. It is embarrassed problem.

Virtual Drives
Some alternatives to DT/Alcohol for drive emulation that do not use SPTD.SYS (In no order).
DVDFab. Very small at just over 1Mb installed and can emulate up to 18 drives.(My preference).
PowerISO (The program is a trial but the drive emulation is free forever).
Virtual CloneDrive

Thanks for your advice. Just one more thing about Command Rate, can I change it with any software, because I can't change timing and other things in bios on my Dell.

Best regards

Sadly no. Its a bios thing. Dell, along with others, lock you out of certain areas of bios to protect you from yourself / they no best.

So if your Command Rate is 1T, then 1T it is.

Hi, I have uninstalled AVG and Daemon Tools Lite, but I have insert the battery, and no problem was detected for 7-9 days. Yesterday, I removed the battery, and today the problem is again here. So, problem is when battery is not inserted. What to do?
