Just built a working computer, but...

[Anomo]

When ever I start the computer the fans (psu, cpu and case) start spinning. Then the case fan stops followed shortly by the psu and cpu. 2-3 seconds pass before they all start up again. What could cause this? Is it normal? I finished the build some days ago, but did not have the seperators that go between the mobo and the screws that go into the standoffs. I built it on the boxes and everything worked fine. Nothing stopped and I even installed the OS.

Now windows refuses to start (even after repair) so I will have to reinstall it, but there are still no clear signs why the fans stop for the short period.

CPU: Intel i3-540
Mobo: Asus P7P55D-E
PSU: Corsair VX 450W
RAM: Crucial 2x2 GB ddr3 something
Case: Ace something

PS: I could probably find the parts with exact names, but the boxes are gone and I would have to look through digital papers :P

Is the motherboard laying directly on the inside plate of the case? I am not sure I understand, or is it sitting on the proper risers and screwed in?
If not then you are shorting out the motherboard and you need to stop till you get risers and have the mobo bolted in properly or you may fry components on the motherboard!

What case are you using? Some cases have built in risers and some don't. If your case required brass standoffs (risers) the motherboard would not lined up with the I/O shield (back plate) in the back of the case. Does your motherboard line up with the I/O shield?

The mobo lines up with the holes. It is standing on its side like a normal computer with the standoffs (seen in jdeb's picture) behind/under it and they are securely screwed into place. They came with the case and should do the job. The fans only stop once during startup. Other then that they keep on going as they should.

Not sure if it was clear or not. The PSU and CPU fans stop. Not the actual parts job :P

I think you may be talking about the double boot? It starts for a second, stops, then restarts normally? Be sure your connections from the PSU are firmly and correctly attached to the motherboard. Make sure no tabs from the I/O shield are sticking in the USB ports.

I pulled out all the mobo power cables and put them back in again. It still double booted (makes sense). Then I took off the cases power cable (to start the computer) and turned it on manually making sure that wasn't the problem. It still started twice. I've decided to take the computer out of the case and try again on their boxes, but don't have time to do it at this moment. More information coming soon.

We've seen a lot of double booting with Intels recently, and I am not convinced that it's a problem!

Update your bios and turn off any overclocking.

right, I am pretty sure that motherboard does that normally (double boot).

[Anomo]

Ok, then I wont pull everything out. Thanks guys

Just one thing, is double booting dangerous? Does it overheat/wear on the parts?

I encountered a problem when trying to reinstall windows. It keeps on giving me an error telling me to put the DVD into the driver, restart the computer and repair. What I want to do is just do a complete reinstallation. It won't let me reinstall or do any of the "repairs" found in the second menu (including safe-mode, debugger, ms with dos etc). I formatted the HDD and updated the bios, but it still sends me to the same place and refuses to be reinstalled. What do I do?

[glc]

I would suspect a problem with either the DVD drive or the DVD itself.

Ends up I just had to enable both APIC and ACPI (or something like that) in bios. It's now sitting in the livingroom installing W7

i had double boots with my i7 2600 k the first days i made my pc. after it was simply gone
