Windows 7 Windows 7 hibernates randomly (and NO idea why)

[Evert7]

Hello. My computer hibernates on random times, I don't have ANY idea why.

Some years ago, my laptop was running vista fine. No problems or whatsoever. Then I did an upgrade to Windows 7 and after a few years it was starting randomly hibernate. I didn't managed to get Windows working properly, and finally I installed linux. I don't have any problems with it. Now I really need windows back so I installed Windows 7 (x64). When I startup and choose windows in grub (yes, my linux is still there) It hibernates after 5/10/50/... minutes. I tried disabling hibernate trough cmd, result: shuts down instead of hibernate. I tried installing windows again, same error. Also, in linux I've made a special .vmdk (for VBox) so that it points to my main harddrive, so in virtualbox I tried booting windows from my harddrive and until now I didn't had problems that way.

My computer is an hp pavilion dv7 2120sb, without any modifications. Problem occurs with and without battery.

So PLEASE help me, this is driving me crazy , and I mean really really crazy . I know quite a lot of computers, but this is just too difficult


- PROBLEM SOLVED: -
Just cleaned my fan, and the problem was gone.

Also, check if your not overclocked in your bios, which can also cause many problems. Best thing to do is to set the BIOS to it's default settings. (You can also try optimized settings".)

I now know that my CPU is way too hot, and that hibernating only occurs when I hear the fans working hard. My CPU is at 80 - 90 °C at normal usage, that isn't normal, uh? I did some googling, and found this:

yay.

Great news! (Not the overheating... )
So now, you need to do some spring cleaning! Check your fans and vents for dust. (You might need to dissemble some parts to get in there. Be very careful when dissembling a laptop. Most manufactures have illustrated guides on this. If you're not careful, when you reassemble, you will have extra screws! Also, it's not like screws from desktop computers, where you can mix and match... every screw MUST go back to where it came from!! (Yes, in this case, size DOES matter! )

Hopefully, it's just a bad fan. There are ways to fix fans (oil the pin) but they are so cheap, just get a new one if that's the problem.

Problem solved.

I disassembled my computer and cleaned my fan. Everything is working properly now.
Thanks everybody!
