Windows 7 - win 7 reboots randomly Kernel-Power

re post 33 like to add that I tried a lot of the solutions that were offered and did most of the testing advised including running mem test for 24 hrs. No fault was found yet the error has been finally solved by taking out mem sticks one by one and determining that one of the mem sticks was faulty.
Please check mem sticks individually to confirm the proper operation of each of them! John

Howdy All!
I'm new here and have the literally same mystic problem as YARO and AIG. I was running Vista Ultimate x64 on my current configuration and everything was OK (except that it was Vista by itself ) then I made upgrade to Windows 7 Ultimate x64 w/o any problem. It was also working OK for almost a month and than absolutely chaotic/random reboots w/o any BSOD started with the same Event log as posted by YARO (and described by AIG) at the very top of this topic.

Well... OK. I made the absolutely clean installation of same Windows 7. Same problem - reboots occasionally happened even in a few seconds after power-up, i.e. before the actual OS loading start.

Well... OK. I made the absolute clean installation of same Vista.
Everything looks OK! At least no reboots...

I understood from this thread that AIG finally settled the matter by swapping PSU to a 50W bigger one, but I failed to find any further comments/replies from YARO...

YARO, AIG and others-who-know... pls help!

Thank you.


oops... bad news. after working fine for some three-four hours Vista was also rebooted a few times with pretty short intervals while installing SP2... DAMN!!!

Try lowering memory speed. It did help for me with this crash, though I suspect that the real issue is the memory modules or motherboard not providing sufficient power to memories.

Since I obviously fixed my problem, I have only kept a distant eye on this thread, and others that I subscribed to when attempting to fix my problem.

IMHO there appears to be a common thread of hardware problems - one guy mentioned replacing his hard drive, others memory, mine was PS. I have also noticed a lot of issues that contain power/electrical problems. It appears that Windows 7 is slightly less tolerant of hardware/electrical issues than its predecessors.

Although my machine does not randomly reboot since I replaced the power supply, I still have a circular reboot error as soon as the ctr-alt-del message shows on the screen. What I did to get around it, was pull the network cable...... once I log in to my network (it is cached obviously), I plug the cable back in and life is great.

I am just too busy to investigate that problem..... I figure that it will get solved eventually..... I saw a ton of internet posts related to that specific problem - again with no singular fix.

Once the larger companies start selling their systems, they will be able to better narrow down the specifics through their help desk data - and forward it on to Microsoft.

Yep, the problem was one of the new memory modules. Luckily I got four of them, so it was really easy to identify the problem and now I'm waiting for memory modules from service.

TO: All people interested

I've successfully solved this problem in the same way as AIG by swapping my original 350W PSU to 450W one.

Hi,

I have/had the same problem. After many tests during 2 months, I found out my processor was faulty. Flashback: I switched my processor with my brother's, now I don't have any problems whatsoever. Today I've sent my cpu to the shop, I'm waiting for the result. Maybe this helps someone.

Guys,

I work in IT for a medium sized company and windows 7 deployment has stalled because of this issue...

I found out if you increase the voltage just a little bit of your memory,board and cpu it then works fine with no reboots. Obviously, your BIOS needs to be recent AND have the option to increase the mem,board,cpu. This worked on 3 PC's that I've tested. Including my own at home. They haven't rebooted in weeks.

I guess Windows 7 handles the power management a bit differently... I've also read something elsewhere about microsoft's acpi power management and it could maybe be related.

Hope this help anyone.

Cheers

That is exactly how I solved my problem.I have chosen XMP from Bios and it automatically increases the frequency of ram and Cpu.No bsods for 2 months....

Good on ya! I was having the same problem with my computer, which was a clearance bargin during the boxing day sales. My colleague who has some extensive experience in working on the companies hardware advised me that it's always a good idea to replace the manufacturers PSU when buying a system with a quality PSU, since the cheapest components are typically used by the manufacturer.

I purchased the Corsair HX450W and could sense the quality straight from the box. It comes complete with a 7 year warranty to boot, so retains the value after usage.

I'm yet to experience the same problem again, which happened frequently on my old Liteon 350W PSU, and it didn't cost me the world to fix it.

I'm hoping I can still use it on my graphics card upgrade I'm planning to get (ATI HD Raedon 4890), as the manufacturer's website recommmends a minimum of 550W. I'm betting that's for the crossfire version though.
