The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Asus M50SA crashing, freezing, locking up at random

Asked by Sc0tte in PC Laptops

Tags: Asus M50SA crashing, freezing, locking up at random

Hi, are there any more solutions to this problem of the MS50SA crashing?

I'm experiencing same symptoms where the notebook will freeze, crash, restart, at random.  After the lock up, i have to hold the power button to turn it off, then unplug the battery before it will even post (start up) again.  Sometimes when it crashes, the screen is full of artifacts, (like the graphic card was faulty), sometimes the screen just doesn't change.
None of the keys work, (caps, numLock, Ctr + Alt + Del)  But the CD drive will eject, and when pushed back in, the HDD light comes on...


Things i have tried which haven't helped:
- Replaced motherboard (Asus repair center did this)
- Upgraded bios to version 2.04
- Upgraded all drivers (including VGA using the ATI mobility modder)
- Run memtest a bunch of times, (even left it run overnight)
- Replaced ram with same specification (Corsair)
- Run checkdisk looking for bad sectors.
- Installed new version of Intel Matrix Storage Manager and removed registry keys.
- Tried running with 1 stick of ram
- Tried running off battery
- Tried running with no battery.
- No external screens mice, network cables, (anything) plugged in.
- Run in an airconditioned environment. (overheating wouldn't be the issue then)
- Formatted using ASUS recovery CD.

There are no events in windows log,,, (apart from, "The system stopped unexpectedly").  I do not think this is a driver/software issue, because the system will crash at random,..  including while i'm running memtest, or in the BIOS, during windows startup, before logon, after logon, after hours of being on, or (most commonly now) after minutes of being turned on.  When there's no load on the CPU, or nothing happening...  it just seems random.

I'm the IT manager for a medium sized business, so i'm approaching this with a few years experience in trouble shooting broken equipment... and i've never been so stumped with a piece of hardware.

I'm about to call Asus now, but i suspect they will have me send it back,..  then return it in 2 weeks with nothing changed. (as people in other forum threads have said)...   I'm at my wits end, and now have a 6 month old $2,000 notebook that's completely useless....  

Is any one else still struggling with this issue? or have any other ideas?
