graphics card exploded (!!!!??????)

So, Ludigel plugs in his 2005 Acer Game PC, does not even turn it on, but then there is a quite loud bang, much like a light bulb imploding (so don't nag if it was an im- or explosion) and the PC refuses to turn on. Graphics cards smelled funny, took it out, plugged in PC (now also with new power supply to make sure), disconnected all other stuff like HDD and DVD-ROM and .... it turns on, the CPU fan starts turning and then the fan stops again. Most likely motherboard fried.

I had the same back in 2004 when a PC actually started to burn (a cable connected to the internal speaker), which also friend the motherboard and ruined the interface to the graphics card (as a diagnosis PCI card revealed which my wife knows how to handle). The apartment those days had flickering lights, so that might be a reason.

Before that, the ACER and another older PC often did not turn on, had to take out RAM and graphics card and then plug them back to get them started.

I've had it with PCs, I bought 3 notebooks over the last year and do not need anymore PCs in Taiwan. Must be the damned moisture here. Notebooks cope with humidity and bad power much better, knock on wood.

So rot in hell, damned Acer, as you lie there, shiny and new (at least looking like it) on the floor, with your blue motherboard and matching blue graphics card. ROT IN HELL!

HDD makes a good enclosure for backups now with a SATA cable and power thingy.

Hmm - the likeliest thing in a PC which could explode would be an electrolytic capacitor. If those are connected with the wrong polarity, they develop a lot of energy very quickly.

I used to have a strong 48V power supply in my "lab", and a stack of capacitors ... Well, I'm sure you can figure out the rest. :-)

Anyway: given that elcos explode as soon as you give them the wrong polarity, it would have to happen pretty close to the time you made the change in the system. It could have shorted something which got the mainboard into trouble, or the exploding cap could have been on the card itself. You should be able to identify the culprit just by visual inspection.

And I always see sparks flying from the connectors of the power plug to the socket whenever I plug something into these extension cable sockets. I mean those "Vielfachsteckdosen" with several sockets on a cable. No wonder wrong polarities arise, I guess. Ah, I only use my Notebooks now...

Funkenflug ... das klingt nicht so gut. Irgendwas ist da vertauscht, und wenn du 110 V auf einem Metalgehaeuse hast, ist das nicht so schoen.

Nimm doch mal so einen Spannungspruefer (ein einfacher Elektriker-Schraubenzieher reicht aus) und schau ob auf Erde und Null sowie auf den Gehaeusen auch wirklich keine Spannung drauf ist. Ansonsten die Geraete Schritt fuer Schritt trennen und rausfinden welches "funkt".
