Bad sector can appear at anytime. I have a perfect HDD, and just one fine day I found out that I couldn't delete a file, after running a scan, bad sector appeared, and formatting it didn't fix the problem. So time for a new drive.

I have another question. !!
If my computer gets restarted repeatedly for about 20 or 25 times at an interval of one or two seconds due to abnormal frequency of power failure ,then will it affect any of my computer's parts like motherboard ,hard disk, central processor ,ram etc....etc.....????

PSU might die due to power spike. A good PSU should handle those situation, or get a UPS. It may only corrupt the HDD data, but will not kill the HDD.

It also happened to me once, PSU killed my whole system.

That's happened to me too. Bad cheap PSU nuked an entire athlonxp system.

Actually I had an ups, but it could not serve backup because of repeated powercuts and low voltage within an interval of 1 or 2 seconds about over 20 times. So , will it affect my pc components( excluding psu) ??/

How does psu kill the whole system?? And what do you mean by the whole system? Does it include ram, motherboard,processor,hard disk?? And how can I understand that which psu is good and which one is not?

What do you mean your UPS cannot serve backups?

Your PSU is a AC to DC converter. Of course if your PSU is affected, everything else will be.

Erm, imagine the PSU is supplying 12V for 12V line, but suddenly it decides to supply 24V, that will kill most devices immediately.

What PSU is good? I usually spend USD100 on a good PSU.

I actually wanted to ask that can the repeated power cuts affect the psu in such a way that the psu corrupts my whole system ,i.e. should I get a new psu after this event???
What do you recommend? I am asking these since I am very inexperienced!!!!

Like I said before, get a proper UPS.

Keiichi · 22nd Sep 2008, 09:58 AM

I already got a new ups,but still should i change my psu for safety purpose ???
