System Loses Power Randomly

Kernel Power events are flat-out CPU power drops. Check to make sure your CPU cooler is attached fully and correctly. Also check all the power connections to the motherboard, especially the 12-pin CPU power plug.

Check to see what else is on the same power circuit as your PC. Items like appliances, window AC units and laser printers draw a large amount of power and can cause a PC to fail. Do you have an Uninterruptable Power Supply (UPS) for your PC?

The disk faults in your event list also point to possible power faults. I advise you to get the power problem corrected first then run a check disk with repair. The file structure on the disk is probably damaged/corrupt due the power loss.

The DCOM events are the least of your worries right now.

Hey Carwiz,

Thanks for your response. As i've edited in my original post, the DCOM errors as well as other event viewer errors have been fixed. I fixed them by updating my chipset drivers.

However the Disk Errors and Kernel-Power errors still occur.

The PC is connected directly to a plug socket which is on the same circuit as a router and a modem and my speakers.

The PSU currently in my computer is an Antec TruePower 650W. Using a meter my PC is pulling less than 200W during normal use.

I find it strange that the Kernel-Power loss only occurs when i'm installing anything onto the computer.

What can I do to isolate the problem?

Thanks

Correct me if I'm wrong but the power loss occurs during and after a Windows update?

I noticed that during updates the Trusted Installer (Windows Module Installer) dramatically increases my CPU, although not enough to cause the machine to shut down, but in your particular case, that might be something to investigate.

You can try to disable that process from running and see if you still have those persistent shut-downs. In the past, I've even seen multiple Trusted Installer processes running causing havoc on my system.

Really curious about your problem and hope someone can come up with a solution.

Hmmmm. Not much help. The system log ends in May. I don't know if it's because of the error or not. The App Log is full of index corruption errors though. You can remove those previous files then check to make sure you have enough disk space. You should be running with at least 10-20GB of free space or Windows will tank on occasion.

Try this updated version called DM Collector. It produces more and is less prone to errors.

I definitely have enough disk space, I have a 1TB HDD with around 600GB free.

I will run DM Collector and post the results back on here.

Speak to you soon,

Hi HelloItsMeAgain,

The power loss occurs during Windows Updates & during Installation of Software.

It's interesting you mention TrustedInstaller, I've seen it listed before but i've never looked into it. I will definitely look into this after troubleshooting through @Carwiz's instructions.

Thanks,
