Overheating Southbridge and shorted HDD...

Do you have a technical question that doesn't really fit a specific console? Want some general info on electronics, hacking, making cookies, etc? Here's the place to ask! Go nuts.

Overheating Southbridge and shorted HDD...

Post by Electric Rain »

I got a 2.8GHz P4 Dell from my brother's girlfriend to fix. It's actually her family's computer, but they're rich, so they just got a new one and didn't bother with this one anymore. It got "fried" by lightning, I guess, so my brother's girlfriend gave it to me to see if I could fix it. It would post, but it wouldn't boot, and it would boot my Linux LiveCD. The HDD was obviously the problem. I popped in Hiren's BootCD and discovered that there were several damaged sectors on the HDD. After about 12 hours of running HDD Regenerator v1.51, it was only about 3GB in (out of 80) and had already found and fixed several thousand bad sectors...

Everything was going good. But, I saw that this process would likely take several days, and I had the hard drive sitting on the floor, hanging out of the tower... I didn't want to leave it like this for however long it was going to take, so I attempted to move it back into the case, but accidentally shorted the HDD with the metal carrier it was supposed to be sitting in. The screen went black, and now I can't get it to do anything. The fans and LEDs turn on, but that's it. No video at all. The hard drive seems okay; I was able to put it into another computer of mine, and it's running HDD Regenerator again just like it was before, so I should be able to recover the data on it. But, the mobo seems screwed. Within a few seconds of booting up, the mobo's southbridge gets hot-to-the-touch (burn your fingers hot)... In my experience, when a chip gets THAT hot THAT fast, it means it's effed. Image

Any suggestions? Seems hopeless to me, but I figured I'd ask anyway. Do you think the fry-age would have spread to anything else? :lol: Meaning, do you think I could just get a new mobo for it and have everything else be okay (CPU, RAM, expansion cards, etc)?

There's a chance the other stuff besides the motherboard is OK. I would try out the expansion cards and RAM in another system before trying to remake the system with a new motherboard.

BTW, the harddrive sounds like it suffered a head crash with that many bad sectors.

Yeah whenever a chip on anything gets burning hot within' seconds of getting power, it is fried.

This happened with my friends HDD from his original Xbox, put power on the drive, but won't spin up, and the main chip on the drives board gets extremely hot.
