I have a prebuilt HP computer that I have upgraded the video card and PSU computer is only about a year old. Just recently I have been getting random shutdown and reboot, there is no blue screen or error when it reboots. It does it at random times watching movie, browsing internet, playing games. When it reboots it goes through the POST screen with no errors and I didn't hear any beeps, instead of loading windows it loads a black screen that states at the top "ENTER BOOT IMAGE: 0.." you can enter the numbers 0,1,2,3; but when you type a number or just wait it locks up and have to hard restart to get it to reboot. It does this in a continuous loop. This is the steps I have tried: 1. Repair using the windows 7 disk 2. restore to a time before I had troubles. 3. Updating all drivers(after the problem first happened) 4. Virus Scan the entire system all files the only thing that does work and gets it to reboot and act like nothing ever happened from the command prompt in the win 7 disk type the three following commands: bootrec.exe /fixmbr bootrec.exe /fixboot bootrec.exe /RebuildBcd after those three i close and restart and it works fine. This problem has been troubling me only seems to be once a day for the past 4 days. I would like to fix this without a clean Install, and please tell me why it works for about a day then happens again.

Is there any prompts before the system shuts down? Please open Event Viewer and open the System events. You may found clues there. Please let us know if it is caused by BSOD errors. What is the model of your computer? I suggest you goto the download website of HP and see if there is any firmware updates for your hard drive or BIOS. Install any available firmware update.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

For this kind of issue its best to make sure hardware is not causing it. OEM computers have built-in hardware diagnostics that you can make use of. You may also call your tech support for hardware diagnostics and troubleshooting. Once confirmed that its not hardware related, you can now safely troubleshoot the software side.http://www.cesabarre.com/
