Machine not stable? Try this tool.

Posted on October 20, 2010

We commonly run into situations where PCs aren't operating correctly.

Common behaviors include:

- Overall instability
- Incomplete bios posts
- The deadly blinky cursor for a long period of time
- Lock-ups while identifying hard drives
- Even blue screens when hammering your processor

Here's the number one rule.
If you have issues BEFORE windows starts loading, you have a hardware issue. Stop blaming Microsoft.

Most people test the RAM, hard drives and eventually start pulling gear out by process of elimination.
What's generally the LAST thing you check?

POWER SUPPLY!

I can't tell you the number of times we've tested and replaced absolutely everything only to finally discover the power supply was the issue.
How do you diagnose? You have two options:

- Pull a separate power supply and plug it in.

- Try this tool:  http://www.cpuid.com/softwares/hwmonitor.html (if you can make it to windows)

This tool can help you identify if your power supply is providing sufficient power.
In our cases, the power supplies were delivering <8v when ~12V is required.

You would be AMAZED the instability your machine will demonstrate without a working power supply.
The next time your machine is acting up (especially on start-up), check the power supply.

Special thanks to Davor Karacic for his mental madness.

  1. Howdy, I have only just received my first computer & to find so much material on the subject of home security & related topics is really great!

    • I think that if you can reuse any materials that you will be safe recuorses and money for your new home. While it might take some creative energy to think of a solution, saving money in a remodel is really important (because everything always ends up more expensive than originally thought).However, if you cannot find a way, try talking to a custom home builder who might have good ideas on how to reuse the windows and make them functional in the new house.
