  Laptop randomly shuts down for no apparent reason 
 Date Written 
David Pantich Dec 17, 2011, 11:38am EST Report Abuse

My wife has a Gateway NV79 running W7 SP1 that is randomly shutting down for no apparent reason and with no error messages. It started a couple of months ago and it would happen maybe once a week or less frequently. Over the last few months it's gotten more and more frequent to the point that now she can't be on for more than an hour or less without it shutting down.

Some of the things I've done with no apparent impact on problem:
- Replaced power supply cord with brand new one from Gateway
- Made sure that it's up-to-date with all W7 updates
- Made sure Windows Security Essentials is up-to-date and it has not found any viruses
- Run CCLeaner to clean up temp file, registry and remove all but essential programs from startup
- Defragged the hard drive
- Tried running in Safe mode

I'm at a loss at what else to try. Anyone have any ideas what could be causing this?

Thanks in advance for any help

Downloaded a utility to measure temperature of cpus and fans. Running pretty hot. So I took off the back of the laptop and cleaned out the dust real good with some compressed air. Working much better now.

Let's hope that's all it was.!

This is a hard drive issue. I, like you also tried every common sense fix. I reloaded the OS and completely stripped it of any programs that I no longer needed. All to no avail. I then took it in to have someone check it out. I was told all was in working order. Laptop continued to shut down more and more frequently. I decided to read everything online I could find with regards to the problem that many were experiencing with this model. I finally began coming across some techs that seemed more than confident in their assessment that the issue was a bad hard drive. So I replaced the hard and the issue was resolved. Hard drive cost about $125. Good luck.

I also have a Gateway NV79 and am having this same problem. So, you say getting a new hard-drive really did the trick? Did you go with a particular brand, or just buy a replacement from Gateway. Gateway isn't worth a flip anymore since they are owned by Acer now. I will never buy another one.

I didn't have to replace the hard drive. That was someone else who replied to my post. The thing that really made a difference was to clean out all the dust from it. Then to keep it from overheating again I got her a laptop cooler for less than $20. She hasn't had a problem since.
