win 7 reboots randomly Kernel-Power

I've had the same problem since early January after two months on a new system. It was at least daily for several weeks and then stopped for almost two weeks and it now back, but not every day. Strangely, it has never occurred between 6PM and 7AM. I have virus scans and off site back ups running during those hours as well as in the day time. I replaced my 850 watt power supply and have run a few passes on the memory. The problem typically occurs when I'm out of the room. Give all the posts I've seen on the web, it seems to be somewhat common. I have different hardware from the other posters so I don't think a specific piece of hardware is causing the problem. I'm just posting to give people a gauge of the extent of the problem. I'll try some of the suggestions posted earlier to see if the problem goes away.

I tried to add this to my original message twice, but it doesn't seem to take.

The BSOD indicates it's writing a dump file, but I can't find it. Is the file type hidden by default?

gcortes:

I assume you've checked in the event viewer in administrative tools under the system event tabs? It's a very long shot since you already have a whopping 850W PSU, but if you've found the logs to be missing there, my guess is that it could be under powering the HDD when it has it's episodes, which could explain the missing event logs.

You could also check the device manager or run an msinfo32 in the run prompt to see if there are any problem devices being detected. It might also be worth telling us a little more of the spec on your system, as the demands differ.

Finally, you could double check to see if all the correct cables from the psu are attached and not loosely fitted, provided you don't void your own warranty (unless custom built).

Hope all this helps

I found the dumps. They had a different name than I was expecting. They all appear to be there. I couldn't figure out how to look at it in Visual Strdio so I used windbg. It spite of downloading, installing, and pointing to symbols, it complained about missing symbols. I couldn't upload on as it didn't like the file type. I have WinRAR so I don't know if I can zip it.

I checked msinfo32 for problem devices and found none. My system is in my profile, but I'll include it below.

The machine is custom built. I've already replaced the power supply. I checked the connections when I put it in. I'm going to install a CDROM today so I'll check again.

Since I last posted, I gotten a number of dumps. Sometime two or three in a day, sometimes none. So far none today. I never had one from about 6 PM to 7AM. I run it 24 x 7, and I do use it after 6 PM.

I have the same Error 41.

Just installed Win 7 Professional (many dramas - turned out to be bluetooth wireless mouse/keyboard issue). I find my system rebooting spontaneously after 90 - 180 seconds after login screen and sitting there with the DVD drive flashing and seeking... no other action til I soft reset.

There was one session where I got in about a half hour setting up wifi and initial drivers before I had to reboot the computer, and the issue started again!!
Tried all recommended checks and fixes (except new PSU... will pick one up this week) - no luck!!

What gets me is that if I boot into my old Vista HP loaded on my other HD, the system continues to run no probs????

Hardware issue? - not in Vista!

Win 7 issue???

I've been building my PCs for 25 years and this has me stumped, so Sorry, I have no solutions to offer... thought it might help with the overall picture of what is happening for us poor mugs. Gotta love M$???

I seem to have a similar problem to everyone else in this thread.
My system has continually played up since I bought it about 5 weeks ago.
My very first power up gave me three blue screen crashes with a "cpu fan error" and 2 beeps on POST. The system was bought overclocked (from 3.2 to 4 GHz) and I assumed this was the problem but during most of these crashes the BIOS reverted to default settings and still produced errors.
Eventually one of the BSODs corrupted my windows installation so I was forced to reload windows and was told by my suppliuer to run MemTest - this gave no errors after 2 hours so the computer was returned for inspection.
It was returned to me fairly promptly (not a good sign!) after the bios had been reset (same as I had done on numerous occasions) and tested without fault for 24 hours.
Guess what happened when I powered up - yes the dreaded BSOD after the " starting windows" screen appeared.
The BSODs vary and include stop:0x24, 0x50 and 0x3b errors. I also am now getting blank screens regularly after the starting windows message and the only way to get over this is to power down and restart. Once up and running the computer nearly always performs OK - it is just the starting phase that gives a problem.
I have tried many of the suggestions listed on this thread including reseating all connectors, memory sticks, video card, adjusting ram voltage , dram frequency, updated the bios, reloading windows (three times so far) without effect.
I have just ordered some different ram to try but am running out of ideas.

Well guys, after much messing around I found a solution (to my problem at least). I was sus on Intel Speed Step, so disabled C1E and EIST in BIOS, and have not had a problem since! Win 7 is stable, and I'm happy . Such a simple fix in the end.

We could actually use the DMP file. Use these to find and upload. https://www.sevenforums.com/crash-loc...d-problem.html Also just as a heads up, it is always better for you if you start your own thread.

Hi,
I have been reading thru this forum and have found other people with the same instances and or error as I do with a couple of PC's that I have recently built. I read the thread that spoke about re-enabling hybernation on Windows 7 Pro, to help address voltage irregularity problems. This did not seem to work. I am a bit confused because I have built 7 of this duplicate systems with the same hardware, but only have one that is exibiting this issue. Could it be a defective PSA ( power supply)????

Hardware Configuration:
Asus M478T-E
AMD Phenom II X4-945

Kingston 2GB x 4 8GB Total - (DDR3 PC3-10600) 1333MHZ
