How I Fixed: Computer Shuts Down When Using CD-ROM Drive


Hello everyone,

Another interesting fix:

The other day a client called me and told me that his computer was shutting down every time that he tried to play his Hoyle Card Games CD-ROM disc.

I went over to his house and sure enough, every time that the CD-ROM drive started to spin up the computer would shut down and then reboot. When not using the CD-ROM drive the computer was apparently functioning OK.

I did some research and found that a spinning CD-ROM draws an extra 6-7 Watts of power from the Power Supply. In other words, there is a significant power drain when any disc is actually spinning up.

I concluded that the clients old PSU was no longer able to handle the increased power drain from the spinning CD-ROM. I replaced the defective PSU with this one, and all was well once again!

My client and his wife were now able to play their Hoyle Card games. Very happy!!

Professor Randy says: When repairing computers, never underestimate the importance of a good Power Supply!
