Windows 7: win 7 reboots randomly Kernel-Power

Just joined the site and wanted to post because I've been having the same issue as the OP: event 41, no BSOD, on a brand new Asus box.

I've tried tinkering with various things including replacing the power supply (original supply was sub-standard anyway), running system scan, moving boot drive to another HD, disabling auto-reboot, changing power strips, &c. and nothing seems to be doing the trick.

The computer randomly reboots about 2-3 times per day and there is no pattern to what I'm doing when it does. Sometimes I'll be reading web pages and using WinAmp, at others it will reboot with nothing running except for the desktop and the basic applications (i.e.: reboot from screen saver but not sleep state).

This problem is driving me insane and any additional suggestions that you guys have would be welcome.

Have a look at post #29 and see if that helps.

Kernel Power Event ID 41, Task Cat 63

Struggled with this prob for several weeks having hourly trips for no apparent reason. Reading a lot of solutions; all fairly complex.. Swapping around mem sticks ( I use 2 of 2 Gb each) I found that one seems to be faulty. Running on one now and no probs for well over a day now despite some severe stress testing. Fingers crossed!!

Tried going into the BIOS and disabling the things mentioned in that post John, but none of them seemed to change the stability.

I see some people have been fixing the problem by slightly upping the voltage to the memory, but that's not an option in my BIOS. The box I'm running has an odd "AI Manager" interface that allows me to up the threshold on the voltage but not to tinker with things more directly.

I should also add that I ran MemTest to see if there was any physical problem with my RAM and that doesn't seem to be the issue either.

I got the same problem, except there is no reboot but rather a total FREEZE without any bluescreen.

Any good ideas how to identify if the power supply is the problem? I bought it recently when I upgraded my computer so the warranty is still there, but I don't want to sent it to service if it's not broken.

I've also ran the memtest image.

Is there a chance, that bad driver is the cause?

It is really interesting that so many people experince the same kind of problems, and the other interesting thing is that the configurations with Bsods are all new like mine.I have a Gigabyte P55 chipset board and choosing XMP(Extreme Memory Profile) which automatically adjusts the frequency and voltage of rams and processor seems to work for me since I haven't had bsods till then, it may be worth trying....

Somebody in finnish forums was having the same problem. He solved that by turning off harddrive sleep timeout from power saving settings. I give it a shot and see for few days if that helps.

And I'd still like to hear ideas how to identify the faulty driver/hardware?

Other suggested solution is to turn of AMD Cool'n'Quiet, so if you got CPU from AMD, give it a shot. I will. Turning of HDD powersaving doesn't seem to help at all.

EDIT:

Turning Cool'N'Quiet didn't helped either, but...

I lowered my DDR3 rams from 1333MHz to 1066MHz and played S.T.A.L.K.E.R. for couple of hours and NO freeze. Usually it crashes in one hour.

I tested my Seagate HD with spinrite and verified that the drive was the problem. I will be sending it in for a replacement. 5 year warranties are great. I haven't had a single problem with any other hard drives in the system.
