Hi,

I left my laptop on and stepped out for about 20mins. When I returned there was a blank screen with the following message: 'No Operating System Found.' I rebooted and got the same message. After rebooting a 3rd time, it worked as normal. I am using Windows 7 that was pre-installed on my laptop. What could have possible causes this? Should I be concerned??

Thank you

How old is it it sounds like it might have a hard drive problem or windows corrupted files or a bios problem, many issues now to just pin point which one. :huh: Did any error messages come up after you got it to work?

It is a new laptop (about a month old). No error messages after it eventually booted up. However, I was scanning various folders for viruses when my computer crashed while scanning an episode (from a tv series). I stopped the scan and tried to to delete the file. My computer crashed again, so I rebooted before getting rid of the file completely. My computer appears to be running error free now (holding thumbs). Do you think it is possible that a corrupt media file caused the above mentioned issue?

It seems you are having some issues with the operating system, some of the files are corrupt.

Try to boot in safe-mode. Press F8 upon boot up and see if takes you there.

What I would do at this point is

A: Repair windows using a W7 disc, but If you don't have one then that can cost.

B: Talk to the Manufacture, since it is a fearly new computer it should not be giving you any of this issues.

JUICYboy:

Unfortunately my laptop did not come with a W7 disc. I pressed F8 on boot up and tried to boot in safe mode, but it got stuck loading (first 2 pictures are screen shots of where it got stuck booting up in safe mode).

I also tried launching a startup repair (see pic 3) and it got stuck at pic 4.

Yes, I will certainly try to get in contact with Bestbuy/Sony.

Update:

Ran the memory diagnostics tool in BIOS and it found no errors...took me directly to another windows startup screen which failed. Attempted to boot up in 'Directory Services Restore Mode' from BIOS and got the following dead screen: http://imgur.com/pEEdf.jpg

Any further suggestions??

Failing all else take the laptop back where you bought it from and tell them what has happened, ans see if they can get it to work, and insist that they replace it, or loan you one well your one is away for repair.

Don't forget it is still under warrenty and as such they should replace it

^I agree. This goes for anybody. If you're having problems with a new computer, take it back. That's what warranties are for.

Thanks for the advice guys, I will certainly contact the manufacturer.

In the meantime, I've got the computer to bootup, but it crashed after about 15 mins. I now have it booted up in Safe Mode, which is an improvement. What should I do now that I have it running in Safe Mode???

Shut it down and take it to the Geek Squad at Best buy and tell THEM to fix it. You screw around too long and the warranty will expire. Simply put, your computer is defective. It happens. They fix them.

Thanks for the reply DeathStalker,

I've done a full system restore, which formatted the C: and reinstalled Windows. The way I figure it is that it might be a software issue, such as a problematic windows update or bad install. If the problem re-emerges (which so far it hasn't - holding thumbs), then it seems infinitely more likely that it is a hardware issue in which case I am left with no option but to take it to Sony/Best Buy Geek Squad. Whatever happens from this point on, if the comp starts acting up again, I'm taking it straight to Best Buy.

If the laptop is that new, DONT go to best buy, they will send it off for 4 weeks, and you might get someting back that works, call Sony direct, theey have good customer service, and will prob just send you a new one.
