Hello,
Actually when I put on my computer it did not start. I heard some sort of noise as if something had blown up. It was the fuse in the spike guard that blew up. I found that there is no power supply to the motherboard. I changed the fuse and spike guard started functioning properly. Still power did not reach my motherboard. Hence I changed my smps and finally it received power. My system was on.but after an hour it again got off, and now whenever I start my pc I does not on. After 2-3 attempts it starts on. Actually I also connected the wires of "on" button of cpu to that of reset button on cpu. Aince the on button of cpu did not work properly. But I am using this kind of arrangement since 2 years and every time it used to function properly,only now my system is causing problems.

First, please stop shouting (ALL CAPS is considered shouting on the Web, pretty rude). This post is off-topic and makes no sense.

My sincere apologies to you for this act of disrespect.I did not know "all caps" is considered as shouting.I am very new to this site.How can I shout or show disrespect to highly qualified people like you who are always ready to guide me.Moreover I mentioned "Hardware" in tag field while posting this query.How come did it reach software professionals instead of hardware professionals.Can you please tell me some other such ethics so that due to lack of knowledge i don't commit such mistakes further.

No problem, as soon as you know it now. Unfortunately, this is a hardware problem with not enough information to repair your system. I cannot imagine the way to fix the problem by just reading your post and answering. It looks like your hardware is damaged and needs hardware troubleshooting or even replacement. Someone needs your machine in one's hands, which is more then any conversation via the Web...

Do you feel better now that you screamed at us about it? What does this have to do with software? Do you think that maybe it is just time to buy a new computer?

DON'T SHOUT. Using all capitals is considered shouting on the internet, and rude (using all lower case is considered childish). Use proper capitalisation if you want to be taken seriously.

It's standard behaviour for the whole internet, not just this site:

You will seriously annoy some people if you do it on some sites! :laugh:

This is the Quick Answers forum. To provide a quick answer we would need a question.

If you look at the logo for CodeProject it says, "For those who code" and the name also implies it is for coders. Many of us still know hardware but this is not a hardware forum.

k actually when u post a question, you need to enter the tag field,in the tag field there is a hardware option too.That made me think one can also post hardware issues.How ever Mr OriginalGriff provided me a solution.Looks like that is the only option I can implement.

Basically, I think you're right out of luck.

What has probably happened is that your "spike guard" has had a spike and failed - at which point it seems to have passed the spike on to the PC (and possibly made the situation worse - some do). The other possibility is that your PSU has failed, and it blew the fuse in your spike protector - in fact this is more likely than receiving a spike in the first place.

What has this done to your PC? Nothing good. The lack of response from the PC when you turn it on most times would indicate that there was (probably) a problem with your PSU, and that since you have changed that and the problem persists, it is likely that it passed the spike on to the motherboard and related components.

I've met this before - a PSU failure that stresses the other components on the computer to the point where they fail as well. and since they all connect to the PSU output voltages...

I would suggest that the only practical thing to do is replace the PC and use a USB disk caddy (like this one: http://www.ebay.co.uk/itm/DUAL-2-5-3-5-IDE-SATA-HDD-DOCKING-DOCK-STAND-STATION-CADDY-USB-CARD-READER-UK-/280935394629?pt=UK_Computing_Other_Computing_Networking&hash=item41690ded45[^]) to temporarily connect your old HDD to the new computer to get the data off it. I would not connect the HDD directly into my new PC - I've seen that kind of stress being "contagious" and stressing the new components as well!
