Ok, so, I know I haven’t been around here in like, years, but that’s another story.
I’ve just installed a new motherboard, Gigabyte 865PE1000, I think. Anyway, I installed all the new parts too, hard drives, graphics card, all the lot. On pressing the power button, the system didn’t start up, at all. I’ve checked the power supply, even tried a known working one. I’ve also checked the power button, that’s working. I’ve also made sure that the motherboard is correctly wired. Still nothing happens when I press the power button. I can only think of it being a faulty MB, anyone else got anything?
Cheers.
May 31, 2006 at 6:23 pm #145578williamleeMemberI had that happen about 2 years ago and a friend of mine who builds computers suggested I remove the MB and put it back in. Now I do not know why or how this could make a difference but it did work. I asked him to explain this and he said sometimes when the contacts are new the coating they use can be just a little thick and not making a good connection and by pulling it out and back in again will often resolve this. If not then I would have to agree that the MB is faulty.
May 31, 2006 at 6:33 pm #145569MartinBradleyMemberWow…didn’t think that would make a difference either. I’ll try it. Do I just remove the motherboard, or remove each individual componant?
May 31, 2006 at 6:52 pm #145579williamleeMemberno just the motherboard itself should let you know it that was the problem.
Now if it was me doing it and having it all apart I would disconnect everything and re-connect it since i was there.
and I am sure that you are aware not to mess with the inner works without gloves or at least making sure your well grounded as static is not a good thing and can burn out a system rather quickly.
Good luck
May 31, 2006 at 8:55 pm #145575SpikeMemberCheck the following things before removing the motherboard totally; thats dangerous, you could short it out just by touching it:
1. Check that you put the power button’s connector on the right spot on the motherborad; also, try reversing it.
2. Check your power supply and that it’s firmly in place on your motherboard (some also have a secondary power source, make sure that’s in, too)That’s all you need to make your computer start up. If it’s still not working, it’s probably dead.

Quote:1. Check that you put the power button’s connector on the right spot on the motherborad; also, try reversing it.Reversing it? How would that do anything? Power and reset buttons are just a momentary switch. This is why you can use a screwdriver to turn on your computer by just touching the pins.
Quote:2. Check your power supply and that it’s firmly in place on your motherboard (some also have a secondary power source, make sure that’s in, too)If it’s a 24-pin power connection, you don’t need the other 4-pin. If it’s an SLI motherboard there may be a 4-pin connection on one or both of the PCIE-16 slots. Check your manual.

The board should not be touching the case anywhere on it’s underside save where the screw-pads are. Make sure you’re using the (probably gold colored) rods to keep the board from touching the case.

What you want (if anything) is to either wear a static wrist band, or make sure you always have one hand touching the case when you’re working on it. But I’ve never had a problem with static before, so I refuse to think it’s a very large issue.
May 31, 2006 at 10:53 pm #145570MartinBradleyMemberI suspect Dave, as you say, that it may be the board not mounted correctly. If it is touching the case, what exactly will that do? Will it have damaged the board when I attempted to switch on?
I don’t think it’s static. I’ve been inside loads of machines (no time for innuendos!), and it’s never been a problem for me before.
May 31, 2006 at 11:13 pm #145565DavidParticipantI’ve only ever mounted one board incorrectly (touched the case) and powering it on smoked the board and CPU… If that’s what’s happened, you’d have to return and get new parts.
Something you can do, is build the computer outside the case. All you need to connect is the CPU/Fan, RAM and Power Supply. If you touch the contacts together (from the case power button, or a screwdriver/peice of metal) and it powers on, your board isn’t totally fried. (It’s possible the chipset or other devices are damaged though, but this will get you closer to knowing whats happened)
May 31, 2006 at 11:13 pm #145576SpikeMemberIf it was touching the case, the best possibility was that it just wouldn’t work, and the worst case is that you fried it.
You want to make sure you put these in as your motherboard risers (most likely the one to the left; I’ve never seen the middle one, and the right plastic one is cheap). If you havent, well, um, I’d get right on that 😉

If you haven’t, you probably fried it like I did. =/
June 1, 2006 at 12:26 am #145571MartinBradleyMemberWell, the board was touching the case, amazingly enough, I haven’t fried it.
I can now boot up to the point of the Windows XP loading logo appearing, just before it appears, my system reboots itself, almost as if it’s overheating. I know it isn’t, as the fan I have definately supports the processor, so I think we can rule out that option.
Any suggestions?! Thanks for your help so far though!
June 1, 2006 at 12:31 am #145577SpikeMemberHee hee hee…I’ve had this problem before a lot of times with new motherboards. I really for the life of me can’t recall how to fix it, but I think it just fixes itself automatically, almost like “breaking in” a motherboard (especially to the extremely hot processor).
June 1, 2006 at 12:37 am #145572MartinBradleyMemberHeh, yeah it happened to me a few times with the old board. It’s so odd, and yeah, it did seem to fix itself, but…there must be something. I didn’t think it’d be totally random like that.
I’ll try the XP Repair thingy off the disc.
June 1, 2006 at 12:41 am #145580williamleeMemberSo did you find out what you did to get it to boot up? just curious.
