Is this normal?

It's not really an issue, but it's odd.

If I switch on my computer after it has been off for more than an hour or so, it'll light up, start humming, then switch off again. A few seconds later, it will start back up again, POST and everything is fine.

This never used to happen with my old motherboard, so I'm wondering if this is something I should be concerned about?

its a feature on the P35 chipset, sometimes afaik

Same board as you, and yeah, same effects here.

Press on button, fans spin, off again, back on and POST.

Never had a problem with it, just assumed it was a "thing" the board did.

OK awesome, thanks. It's a second hand board so I was worried there might be a fault with it.

you`ll find it`s the power to the graphics card,for some reason it powers the card first,if you get a higher power supply with more rails you don`t seem to get the issue.

Agreed. I have recently built 2 PCs for my family and experienced the same problem. If you ring round you will find that it is one of the querks with some motherboards with this chipset that everyone knows about except for you.

Nah, it's not a problem unless it leads to something worse later on.

I didnt mean you in particular! It has always been the same..if you are building PCs regularly, you come across a problem, only to find that it is a common problem that you have encountered and no one has bothered to post or make a comment about it. I found out when I rang the supplier, only to be told "didn't you know about this? It is common knowledge!" IMHO, an addendum should have been added to the particular motherboard manufacturers manual advising that this could happen.

I have 4 P35 mobo's here which DO NOT do this!!
Plus I wouldn't be too happy if it did as it's not going to do your HD's any good double booting like that tbh.

JimAroo · 9 Jun 2008 at 16:48

Yea i've had 4/5 P35 mobo's and my mates had a few. only our ASUS boards have done it, no others.

I don't have the PCs to hand, but both are the MSI P35 Neo -F boards. They dont POST anway as it always happens within perhaps 1 to 2 seconds. I do not think it will have any effect on HDs as they are built to stand a lot of cycling.

SlyReaper · 9 Jun 2008 at 16:57

Yeah, the first attempt doesn't POST so it's not touching the hard drives. I don't think the drives even get spun up by that point.

yep happens once in a while on my p5k-e

Super_Sonic · 9 Jun 2008 at 19:51

As soon as the PSU is activated the HD's will receive power and start too spin up.

P.S) 2 of the P35 mobos I have here are Asus's and neither do this :confused:

g00dsh0t · 10 Jun 2008 at 02:40

when you turn your pc off, do you turn it off at the plug?....if so, i think it checks bios settings before the main start up....P965 chipset mobos do it also

It appears Abit had the problem last year.
