About two weeks a go, I ask for some help with (DISK DEFRAG). Got good response and ideas what to do to get it to run. Had all kinds of error messages, so on and so fourth. (to now avail) Gave up. A few days later my power supply on my computer gave up !!. Replaced it and forgot about Disk Defrag, until today. Guess what !!! ::), Ran fantastically ;D. Think there could be a correlation here :o
Hi…
Absolutely. 
I worked on a client’s system once that did not run correctly at all in her house (where it was plugged in) but when I brought it to my house, it worked fine. The only physical explanation was that the power source where it was plugged in was not operating correctly.
Best Regards…
Yup, a bad power supply can cause all kinds of wierd errors and problems. As ardvark stated.
And of course when in doubt, it is quite easy to check your power supply to make sure its providing the proper voltage levels to your system.
