Weird powering up problem
« on: April 08, 2008, 06:30:23 am »
Hey guys, looking for some suggestions here....

I had to move my computer from one room to another temporarily last night, it was running fine where it was. Then once, I powered it up in the new location, it starts up for about 5-6 seconds, then shuts off. If I leave it be, it'll try starting up again after about 5-6 seconds by itself, then shuts off again. It seems to repeat this cycle over and over again until I completely cut the power to the tower, or hold in the front power button to turn off the machine.

During this time, there is no display on the monitor and of course the machine does not post. I'm using a Gigabyte motherboard with an Intel Core2 Duo 2.4 with 4GB ram, 8800 GTS, Corsair 520 watt PSU, 1 HDD and 1 DVDRW, 2 case fans, 1 tv tuner. Unfortunately I don't have any extra parts for this computer that I can swap in.

So I'm looking at the best guess of something to replace. The heatsinks and fans seem to be securely in place and the tower was moved very gently. I probably only moved the tower about 25 feet. I also tried a different power bar, different power cord, and a different outlet. In fact, my other computers work with the same cords and setup. So I know it is something with that computer.

I'm thinking possibly power supply right now. Could it be that the 520 watt PSU was too little for what I was running? I'm open to suggestions.

Thanks in advance.

Probably my first guess would be PS, I think 520 should be enough, its just possible that the PS is on the fritz and has packed it in. I'd try the PS first just because its pretty easy to swap another in to test

Second guess, Motherboard. Seen it a few times where the motherboard dies an causes those symptoms, unfortunately its not all that simple to just "swap" another motherboard in to try...

I got a brand-new case once from a (nameless) company and it did this when a system was installed.  For some reason, the power button was toast.  Try unplugging the "power" cord from the motherboard and using a screwdriver to jumpstart it by momentarily touching the two pins.  If it works this way, it is a sticky power button.

This is my best guess as I had the exact same timed problem.  Obviously you can wiggle the heck out of your power button instead of pulling the system apart as well, but this would ensure that the button is not the culprit.

I actually did just that Zeus, before I saw your reply. I've unplugged all the unecessary devices to rule those out. I replaced the power supply with a brand new Antec one, and the same problem still exists. I'm beginning to think it is a motherboard or CPU problem.

Pretty bizzare considering it was working fine, I shut it down to move it about 25 feet and now it doesn't start. Knowing my luck, its probably the motherboard thats shot....dang Giga-byte.

One thing I'm noticing...although I didn't think of it being a big deal at the time, is that when I push the power switch, the case fans come on immediately...but the CPU fan doesn't start up for about 3-4 seconds after the case fans are already running. After the CPU fan starts to run, then thats when the system shuts off for about 5 seconds or so then it tries to boot up again.

the case fans starting 4-5 secs before the cpu fan is normal on a gigabyte board, my new one does the same thing, freaked me out the first time I booted it up. I think it actually powers up the board, then when the cpu fan starts, it starts its post (from what i can tell).

I know you said you tried a different outlet, but did you try the original? just to rule out a faulty ground on a separate breaker that your other rigs might not be so sensitive to.

did you try pulling the mobo out and re-seating it to make sure a case screw didn't come loose behind the board during the move, causing a short on the board? Thats about the only thing I can think of that would cause it to go during a 25 ft move.

I did go back and try the original outlet... and I do have my old computer running in the same spot where I noticed the problem with my current one, so I know its not external power thats causing it.

I was thinking about pulling the motherboard out and seeing if I could get it to go just having it on my desk. All the screws were tight...but I guess that doesn't mean there can't be a short somewhere.

I pulled the motherboard out and ran it outside of the case. Same problem. So then, I tried to run it without the CPU in it. It would stay powered on, but of course didn't do anything without the CPU. At this point, I thought it was the CPU that was toast.

Just to confirm what I thought was the culprit, I took my motherboard to work, and tried another working CPU from a computer and then it still did the exact same problem as always. So at this point, I believe the motherboard is toast. I did all this testing with only the motherboard, Ram, power supply, and cpu connected, using a screw driver to jump start it everytime.

I'm going to buy another board, because I don't want to wait for warranty before I'm up and running again. This board is a Giga-Byte GA-P35-DS3R. The replacement is the DS3P...not sure what the difference is off hand but, is there a better choice out now that I should go for? It would be nice to go with the DS3P board cause hopefully I won't have to do the whole reinstall of Windows. But if there is a far superior board out there, then I'm all ears, and I might just have to suck it up and reinstall.

thx

I have the newer DS3P board myself, and its great. There is one other board on the market that you should really take a look at:

other than that, Id stick with the DS3P and save the reinstall

We've had nothing but horrible problems from the Gigabyte boards here at work.  We were using them for tills and workstations but stopped after at least a ~33 percent failure rate.  I'm not saying that Gigabyte is bad in general but it seems they've had some really bad batches lately.

BTW Our symptoms were exactly what LobbDogg was experiencing.

Hmm, not sure I have much faith then, if this seems to be a fairly common problem. I've had somewhat bad luck with Giga-byte boards in the past as well, but decided to try them out again. Seems like they haven't changed much.

Any other suggestions? Even if using a different chipset? I'm willing to reinstall Windows if I have to.

What about this one? I've had good luck with MSI before and like their boards.

That's not a bad board at all.  I've had one and liked it lots.  In fact I've still got in all boxed up and sitting on a shelf.
