Windows 7: Computer will not POST, video attached

Computer will not POST, video attached

Hey all,

I seem to have this problem whenever I disconnect the power cable from my desktop, but after adding on new HDD's or tinkering inside, I can't get the computer to POST. Usually what ends up happening is I sit by the damn thing for an hour a day, taking the power cable out, putting it back in, and powering it on until it works, but I was hoping someone might have a more enlightened approach on how to fix this.

The desktop survived some water damage (idiot at my party dropped a drink inside), and after thorough cleaning and drying, I got it back to operational status. The PSU was making weird sparky noises when I was tinkering with it, so I replaced that (figuring it would burn the house down at some point), but all the other parts are the same.

Once again, when I get the power cable "right", I can turn off the desktop and turn it back on without a problem.

Here's a video of it trying to start up, notice the two mechanical clicks at the end before the computer turns off. If I don't touch it, it will continually try to boot up.

Thanks!

I had even more issues with the old one, in that most times the computer wouldn't even turn on. But getting a new PSU unfortunately didn't solve all of the problems

Ok if the computer did not POST after the new psu. Make sure and check all the cables over again. Check the mother manual if possible. Give me the mother spec's I can give you a link to the manual.

Oh sorry I mean I got the new PSU over 8 months ago and the computer has worked since then. All of the cables should be good, as it was fully functioning less than 24 hours ago and all I did was add a few hard drives (which have both power and sata cables properly attached)

Oh ok so. The hard drives should not cause post to stop running. Unless the Motherboard got a bit of ESD . Em did you try to remove the HDD that you installed and leave it back to the one that was working?

Just tried (unplugging both the power and sata cable) and same problem. This also happened when I moved the desktop to another room, so it literally happens when I unplug the machine

edit: for what it's worth, it now turns off at random parts of that cycle (sometimes doesn't get to the two mechanical clicks)

Enhanced your video a bit, it's only 5 secs long though.

To be honest it seems to be as if the MOBO is fried. Pluging in and out the power like that would not help. I can't really help much more as it seems to be a problem within the case. Since you can't even get POST to show it is a major problem . Maybe if you brought it to a repair shop. Or even if someone on this might join in a see. But to be it could a ESD problem. Becuase the system should at least POST

Thanks, derekimo.

benjy206, honestly I've sort of accepted that this is a screwed up rig, I was hoping that there would be something like resetting the CMOS battery that might help out. Otherwise I'll just continue chugging away at this, and hopefully not ruin my main hard drive from all of the booting
