Thread: Want to guess what's broke??

    Default Want to guess what's broke??

    There were a few heavier thunderstorms that rolled through my area last week and took my main computer down(as if it were unplugged).
    What do you suspect it is that is broken???

    Here are the conditions.
    I leave the tower on ~24/7, the monitor was in standby. I have two newer UPS(different sizes) powering all essential equipment. My CPU and GPU are watercooled, I mistakenly put the external WC portion(pump,rad,fans) on a different UPS(the smaller unit with the monitor/router on it as well).


    What I've done with the little spare time I've had to look into it...
    I've "reset" my PSU/MB by turning the PSU switch off/ (this not working) unplugging and hitting the power button. This has worked many times in the past and I was expecting it to work here as well...but I got nothing...as if it's unplugged.

    When I pulled the side off the case, there was a noticeable smell...more of a blown capacitor type smell than an overheated electronics smell....but was so faint I can't be certain.
    The MB power LED is not lit.

    My first guess was that the CPU was fried due to the smaller UPS running out of battery before the larger UPS(with the CPU) which turned off the pump while the tower was still running...I know AMDs overheat protection isn't as good as Intel's...but it "SHOULD" be able to cut back enough to protect itself in this situation...I say "SHOULD" because I have it overclocked with a bit more voltage. With this in mind I'm now pointing to a PSU....yet it is a little over a year old and is an Antec TP2-550..but shouldn't the UPS have protected everything from a power spike?? Nothing else has turned up damaged.

    So, before I order a PSU/CPU or even MB I was wanting to run this poll to see what everyone else thought it just might be.

    stick your nose against the PSU - should be noticeably stronger smell

    That CPU should shut down before it is damaged. I never noticed AMD's protections being any worse/better than Intel's. It is more the motherboard than the CPU anyways that does the shutdown. I would suggest a PSU first, if possible borrow one from someone, even if you just slap in a cheapo special just to see if the PC fires up.

    I got to take a better look at it today. I tried smelling, but couldn't get anything. The case has been open since I first looked though.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /><o:p></o:p>

    I have a few PSUs around here, but none are 24 pin...I went ahead and ordered one of these...<o:p></o:p>

    AMD may have gotten their act together, but in a worse case scenario(100% load and yanking the heatsink) The AMDs would fry(I forget the exact chips tested...), the P-IIIs would lock up, and the P4s would throttle WAY down, but remain running.

    I don't believe the CPU is the problem, but with it being overclocked, overvolted and naked...with a possible waterflow stoppage, I can't rule it out 100% either.

    I had time to pull it apart. I tested the PSU with a jumper and nothing happened...not even a 5 volt "standby" voltage was present when plugged in. So we know the PSU is bad...I'm just hoping that nothing else went out.
    The new PSU should be here Thursday...I'll find out then I suppose!

    Alrighty.. After getting the new PSU in and everything connected I hit the power button before putting the tower back in the desk. Everything seemed to be going OK until a power off after about 8 seconds. I started pulling things, the sound card, the video card, all but one stick of RAM, etc. It came down the CPU, everything works fine after installing my old 3800+ so it seems the storm took out the CPU as well.

    Ouch. Now when I get a new rig, I would wire in a 12V watercooling system to run off one of the Molex hard drive connectors.

    I confirmed last night that the keyboard was also taken out by the storm. It was a newish Saitek USB keyboard.
    It basically skips and repeats keys I press at complete random. I hooked it up to my laptop and it does the same thing.

    Such a strange list of components to go out from a power surge.

    Anyway, I just wanted to update just in case anyone else wonders if power spikes can take out hardware sporadically. PSU/CPU and keyboard have been confirmed dead/unuseable.
