Ok started with a new build went to put on windows and everything was going fine. When it restarted i lost my video signal to monitor and the comp seemed to hang up on booting but u could hear the fans and most things on but no hdd activity. So i hold button power it off turn it back on. It continues and i get windows on but the problem for restart still exists no matter how u try to restart. I start to think i have mobo problems maybe i need video card. I will cut to the point though. I send mobo back to company it tests fine i buy video card still same problem. I give up and it sits for some months. I must add computer works fine beside the no restart as long as u turn off and turn on. In the end i buy all new stuff and test things one by one. Still same problem i upgrade to windows 7 still same problem. In the end i have new mobo new cpu new hdd new memory new video card new case. I have tried different cables about everything a person could think of. Even stuff i had read online that closely matched my description didnt work. So now i am at a loss and want it fixed. I have a second comp now just trying to figure this out. At some point i will put that together and see if i get same problem, as they are the same items i started with the first time. I know every item i have is not defective and the monitor worked on a different computer fine. So now i can only think that vista 64 has some problem and maybe windows 7 didnt fix it on upgrade but honestly i dont have a clue anymore and feel like a first timer at a building a comp. Please help anyone this isnt my first post online but so far have never gotten a reply i can give more stats for my parts if needed but i am using different ones now then when problem first showed.

The only thing I did not see replaced was the power supply. You might try swapping in a known good one. Note that most motherboards require an additional power connection besides the normal large 20/24 pin plug. And many graphics cards require additional power connections too. Fans spinning indicate the presence of +12V, but is not an indication the required +5VDC and +3.3VDC are there too.

Are you taking care not to cause any ESD damage - static discharges from your body, smaller than you can detect, are more than enough to destroy ESD sensitive devices such as memory modules and CPUs.

Did you apply a proper layer of TIM?

And note a common newbie mistake, and one often done by distracted experts too, is using extra standoffs in the case, mounting one or more where there is no corresponding motherboard mounting hole. Cases are designed to support 1000s of motherboards so they typically have more mounting holes than the motherboard. An extra standoff, the bottom brass piece illustrated below, can short circuit the motherboard, often destroying the board, but sometimes, if lucky, just temporarily disrupting operation until any extra standoffs are removed.

Actually it is a new power supply. Have a coolermaster silent pro 700 and a xigmatek 700 watt. Both new. I have even replaced the cpu both times getting not to much thermal paste but a good coat. I also bought a coolermaster haf 922 case a nice upgrade from the thermaltake i had. It actually had raised areas built into the area that was the standoff so no room for error on that but was suspect to me. The new case which again i will say i love. lol It had a lettered key to where u needed each standoff depending on atx or micro atx mobo. The next thing i will try is to do a clean install of windows 7 versus the upgrade from vista. See if that helps or changes anything. I also have to say that i am 90% sure i had my only restart ever on this comp or the first one i built. I ran the startup check several times like i read somewhere. Which didnt really do anything for me but i saw the memory check. Even though i have tryed two diff sets of 2x2gb gkill memory i ran it. Everything was going fine on it. I had went afk for a minute while it ran. I missed getting back in time and it said the computer would restart after it was done. When i got back my computer was sitting at windows login screen. I cant be 100% sure it restarted but sure looked that way. I find this very odd that its the only time the computer has ever restarted. I am getting poor over this but i ordered another set of 2x2gb memory this time some crucial. I also wear a esd strap or ground myself constantly on the power supply. Was glad to see a reply of some sort finally even though not the answer or help i am looking for or havent tried yet. So thank you

According to your manual here, your case definitely uses standoffs and screws. The case even comes with a standoff socket - nice touch! I don't see anything about "raised areas".

It had a lettered key to where u needed each standoff depending on atx or micro atx mobo.

As I said before, cases are designed to support 1000s of boards. There is no ATX (or µATX) standard that requires every motherboard have a mounting hole in every standoff location the case has! This means the case will often have more hole locations than the motherboard has or needs.

If the motherboard came with that lettered key, I would feel better. But the case makers do not know what exact motherboard is being installed. The ATX Form Factor standard for motherboards (all ATX sizes) only says where mounting holes can be located. It does not require they be used. So you need to ensure there is a case standoff only where the motherboard has a corresponding mounting hole.

Sometimes it is easier to pull everything out of the case and set it up on a breadboard or other flat, smooth, non-conductive surface. Then you don't have to worry about standoffs, and you can see all your power and cable connections easier.

U must of misunderstood but i dont claim to be the best writer. It was actually the thermaltake case that had the raised bumps that were makeshift standoffs. The new case had the lettered code for each standoff u needed and my mobo needed one in each spot. Btw i actually found on ebay a case that is open to do just like u said witih the breadboard. Its a open case and everything is there for u to inspect and troubleshoot. Very nice was only like 39.99 i think i may just get one for future troubles or new builds. I dont just build my own i build for other people as well.

I like this: Top Deck Tech Station (standard): HighSpeed PC - Home of the Tech Station open air PC workbench

The new case had the lettered code for each standoff u needed and my mobo needed one in each spot.

Again, the letter code for the case just gives you an idea where standoffs might be needed. In other words, don't pay must attention to what the case says. Only the motherboard can tell you where a standoff must, or must not be used.

Are you trying to go to 7 64 bit or 32 bit? You can only upgrade from a 64 bit version of Vista to a 64 bit version of Vista or 7. If possible I would recommend a clean install to an upgrade.
