Power and blank screen

By skydiver38 ·
Hey guys.. just searching on the net came to this site.Its wonderful
i have searched a lot but not been able to find info on my problem..

my computer got busted during power outage in the building.
now... I got a new powersupply and seems to work well but only when my Harddrive is not connected.
When HD is connected through the powerlines, the computer doesnt boot up and no power at all to the system. but when i unplug the powerlines, the system boots up perfectly.

I checked the IDE data cable, tried to switch it around but obvisouly cannot as it has that hook which doesnt allow to insert wrongly.

So the question is, any idea what could be the issue here.

I will be getting a new HD, but until then.. i wanna see what was teh problem..

thnx everyone.

Could be the hard drive

by mjd420nova In reply to Power and blank screen

The hard drive is the part that draws the most current from the power supply. If it's a new power supply, then the drive is faulty. You could remove the drive and try rotating it by hand, then plug it in again. Possibly the platter or motor has gotten stuck.

Try swapping the internal power cable

Welcome! Glad to hear you like TechRepublic.

Your problem does seem unique and puzzling. I would recommend unplugging the internal power cable that connects to the hard drive and connect it with a different internal power cable.

See if that makes a difference.

Regards, Jason

same problem

I had the same problem and it is what happens when the power supply blows.A circuit has blown on your motherboard.

Are you saying ...

by jasonhiner Moderator In reply to same problem

that it sounds like the power supply blew and that killed a circuit on the motherboard?

If that happened, then I would think other things would have malfunctioned or that the system would be unbootable. Right?

Not exactly

by w2ktechman In reply to Are you saying ...

It depends on what was blown on the MB.
My first suggestion is to plug in a different HDD. It most likely blew the hard drive, and if it is causing a short, the new PS protects itself by shutting down.

Although many PS's have safety features to prevent the MB and other devices from being destroyed, it still does happen. So your MB may still have a problem and needs replacing. If that is the case, there may be othr affected devices. But I stand by hooking up another HDD first.
