Windows 7: Frequent Unexpected Shutdowns to No Power-Same Pattern in Event Viewer

Frequent Unexpected Shutdowns to No Power-Same Pattern in Event Viewer

Greetings - I have searched for months but cannot fix this on my own and appreciate any help, please.

Shutdowns occurring in front of my eyes or when I'm not looking; cannot discern any particular software or drivers at fault. Loses all power and stays off, like a power plug pulled. Happens at my home and others as well, with home PSU or my travel PSU (both OEM) and carefully handled over the years, as well as on battery power only.

I had these issues before the new hard drive & Win7 OS installed Sept 2014. Shutdowns began shortly after again; now shutdowns much worse again. Do not believe it's temp related; I run a fan nonstop under the laptop which is in the air on a platform with cooling pad underneath, regularly shoot canned air in; temps read avg mid-40's C and stay displayed in systray, so I watch carefully. Happens with 2 different PSU's, carefully handled, also on just battery power. Did a power drain recently for static buildup; coincidentally or not, was better for a week. Have run chkdisk, memory tests, check for driver updates, and other system tools; no problems detected.

Event viewer seems to have the same patterns leading up to the shutdowns, but things I've tried from searches are ineffective. Here's the pattern, after manually restarting after a blackout shutdown.

Event 219, Kernel-PnP - Warning
The driver \Driver\WUDFRd failed to load for the device WpdBusEnumRoot\UMB\2&37c186b&0&STORAGE#VOLUME#_??_USBSTOR#DISK&VEN_GENERIC-&PROD_MULTI-CARD&REV_1.00#20071114173400000&0#.

Event 1001, Dhcp-Client - Error
Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x00255668193D. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server.

Event 6008, EventLog - Error
The previous system shutdown at 6:16:48 PM on ‎5/‎6/‎2015 was unexpected.

Event 41, Kernel-Power - Critical
The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly.

THANK YOU in advance for helping! Much appreciated.

mid-40C temps are very good, but how are you monitoring temps? Some progs monitor CPU but not MB (graphics chip). With laptops, it's most often the graphics chip that causes overheat problems.

The two events leading to the shutdown may indicate hardware failure. Is there any connection between shutdowns and moving the unit? Has it ever been dropped?

You might run the machine overnight off a linux boot disk and see if the problem occurs. If so you will have a pretty good idea it's hardware driven.

Thank you for your reply. I am monitoring the temps with Core Temp and CrystalDiskInfo. Both are pretty close; CT is a bit higher. Right now, 2 cores are 47/44.

No, it's never been dropped. No connection re: moving it. It's been on its platform for 2 days, and I've had 6-8 shutdowns yesterday and today. No access to anything linux.

Hoping the event viewer logs will be a clue.

Does Core Temp cover the graphics chip? Does it feel hot to the touch anywhere?

You can download Puppy Linux, for instance, and burn it to a CD. "Slacko" Puppy is only 160mb.

I think finding my gpu temp for the integrated card will be very difficult for the logistical reason below that I found this through a search:

Since the g card is integrated on the motherboard, there does not appear to be a built-in temperature sensor for the GPU. (This tech helper goes on to say to the writer However, you might be able to estimate it based on the other values. You can probably assume that it is the same temperature as the nearest sensor (within 1 or 2 degrees C). So to answer your question "Is the temp the same as the temperatures of the cores?", it depends on the geometry of the board and how far the GPU is from the CPU (since you have no obvious GPU temperature sensor).


Would it be prudent to explore the event viewer logs before downloading the puppy thing?

Speccy will read GPU temps if they're available. Maybe someone else can help you with the event logs. I'm really not qualified. I'm just telling you how I would go about it.

I appreciate that very much, Paul. I did pursue the overheating angle early on and believe the fan and air can are doing the job, and readings do stay in the 40's. I watch the readings in the systray constantly. I don't think I can get a separate GPU rating with the card integrated on the MB tho. Neither of my tools show a separated reading.

Thank you.

More clues perhaps?

In case this is helpful, I forgot to mention that I have been keeping a Toshiba usb portable hard drive connected. Also, I have an HP wireless laser printer. However, I was not using the wireless feature of that printer before the HD + clean Win7 reinstall last September, and I had shutdowns then too (which I expected the reinstall to cure but it did not).
