Power supply or graphics card?

By brightmal ·
A few days ago my PC shut-down, as did one of the fuses for the house. This was accompanied by a nasty burning, ozone smell. I reset the fuse, plugged in the pc, and the tower wouldn't light up. The monitor and speakers, on the same cord board, powered up, but not the tower.
I cleaned out all the dust I could find, and tried again, but no luck. I couldn't find any burn marks, but I figured it must be the PSU. So I ordered a Sonata 3 complete with an earthpower 500 watt PSU.
My new stuff arrived today, and I began pulling out my mobo to put it into the new tower, when I found a loose component rolling around in the old tower. To my ignorant eyes it looks like a tiny capacitor and it has written on the top:
6P
100
EZA
There are three more of these on my Asus 7900GT, so I figure that must be where it came from, but this leaves me with two questions.
1/ Would this missing component cause the whole PC to not start up? Have I found the cause of the problem and can I assume the old PSU is still ?
2/ Can this component be soldered back on, or I do I need a new graphics card?

check to make sure if that is where is came from, though. it will be two hole on a board.

as for q1, could do, electronics are crazy things.

q2, you can, but i would recommend not. it is probably easier to get a new graphics card (or what ever it came off) then trying to fix the old one

May very well

Have I found the cause of the problem

Again maybe

can I assume the old PSU is still ?

Defiantly not it could have blown a fuse inside the PS or dome more damage. If this component got hot enough to malt solder and fall off it's most likely gone to Silicon Heaven and taken the Circuit Board that it was attached to with it.

Can this component be soldered back on

Not recommended but it may be possible to solder a new one in place if you know what you are doing with Electronic Repair Procedures

or I do I need a new graphics card

Anything is possible here depending on any visible damage to the Circuit Board where this was attached it may be possible to replace this component with a new one but if it got so hot to melt the solder and fall off similar components are likely to have suffered similar damage. You can try to repair the Circuit Board where this component came from but it may very well be a long process and cost more than a New Card and still not work. You also need to inspect the Copper Tracks on this Circuit Board for signs of damage.

Different scenarios

1) Would this missing component cause the whole PC to not start up?

Yes.

Have I found the cause of the problem and can I assume the old PSU is still ?

You could have a bad video, PS and motherboard or just a bad video card.

2) Can this component be soldered back on, or I do I need a new graphics card?

Doubtful. You'll need a new card.

Good luck!

All sorted now

by brightmal In reply to Different scenarios

I put my PC innards into a new case, with a new psu, minus the 7900gt. Everything powered up fine. I ordered a new 9600GT via ebay, and then found a mate who soldered the capacitor back on to the 7900. The old card now works as new, and I have a new one on the way via ebay. All is good now with my pc.
Thanks folks.
