Computer restarting for no reason (Windows 8), please help!

[Julio Kirk]

So, I'm freaking out here, because my computer keeps restarting after a few minutes. It has happened about 4 or 5 times now, sometimes after 2 minutes, sometimes after 10 minutes. It doesn't follow any logic.

Yesterday everything was normal, I played a lot, turned it off and went to sleep. I woke up today to find it restarts for no reason, and I'm really pissed off. I'm writing this fast, because I don't know when will it restart again.

It happens like this: I turn the pc on, it boots, startup programs load, and I start doing my stuff. After this, it might restart at any moment. No error messages when I boot again.

This is it guys, please help me.

Does it happen when you start up in safe mode too?

What / how old is your power supply?

I would suggest a format, this could be malware or a program telling your computer to restart

Is there anything in your event logs that might point towards a cause?

Sorry, I really don't know. I got so pissed off because I need the computer, that I didn't think of trying in safe mode. Things happened quite fast.

I considered this possibility too. Something similar happened here a while ago and the cause was a dying power supply. But the one I have now is brand new (2 months of use, bought new) and powerful. I'd be surprise if the problem was the power supply, really...

I checked it and... no. The only error occurred on the first time I turned the computer today, according to the logs, was about 2 minutes before it restarted. The error said something about a hive (?). My system is not in english, but I'll translate the error. It goes like this:

"An E/S operation started by the registry failed in an unrecoverable way. The registry could release the hive (file):"

Another log entry said something about this "hive" right before the restart, but wasn't an error.

Sorry about the massively late reply to this but the 'Hive' it's describing here is referring to a registry hive file. Most likely the ntuser.dat file within your login profile. If this is still a problem for you, try the following. Login with a different account and create a new account under control panel > users. Login to the machine with this account and test it. If it works this is your problem, you will then need to copy everything from your existing profile into the newly created one. It's probably best to google creating a new account for some instrucitons if you don't know how to do it because depending on your operating system / setup there are a lot of different permiatations of what you would need to do.

No problem, and thanks for the answer. A few days ago I decided to go and test by myself to find out what the issue was. Well, it turned out it was my PSU. I replaced the new one for an old one I had here: Never had blue screens or sudden restarts again. The problem is the defective PSU had, like I said, only 2 months of use. The PSU I'm using now is almost 4 years old, makes a bit of noise, but it never failed. I really don't understand how the new PSU failed like this and how the old one still resists...

Just out of interest can you name and shame the PSU? I've read all the things online about cheap PSU's but I still had to try one once... it lasted 2 days. Never buy a cheap PSU.
