Re: pc turns off before POST
Odd one...
I'd lean towards the Mainboard as well.
Have you run memtest ?
Re: pc turns off before POST
i haven't done much testing really, as the pc still works, well it does crash after an hour or so though.
its really annoying as i always try to find ways to have the system boot faster and then this just kills it.

Re: pc turns off before POST
I've had similar and because of two reasons, the first is bad contact between the CPU and HSF and the shutdown was a thermal warning, the second was a PSU issue, a cheap noname OEM that ended up in the bin. Since I've always used abit mobos I've found that they sometimes get themselves in a twist, cmos reset and/or formware upgrade is advised although now support is non existant apart from some great peeps on here

What did you do ? Could this cause your instability ?
Re: pc turns off before POST
Asus boards used to that when overclocked, it was "one of them things" ??
Re: pc turns off before POST
i have not overclocked it in anyway, it was a new build with second hand parts, when i say i try to get the best possible boot, i mean, stopping all the start programs, buying fast hardware etc, but this is obviously a hardware issue as i have not even tampered with any settings for overclocking and its been like this from start, i just didn't know where to start.
just also realised its an asus motherboard, sorry for the mix up:embarrassed:
Motherboard: Asus A8R-MVP
cpu: athlon 4400 x2
RAM: 2gb ddr1
PSU: FSP, 500watt blue storm
HDD: 500GB WD 16mb (shows SMART fault at startup, reallocated sectors or something)

Re: pc turns off before POST
Heat ? What temps are you getting ?
Could be the HDD, Can you remove and boot from a DVD and see if it repeats.
Re: pc turns off before POST
it does it on a cold boot as well as normal booting, so i doubt its the temps, the cpu is around 40c.
i will have to try booting from the cd tomorrow (like iv said its my brothers pc)
but just to make it clear, when you say boot from CD, could that be the windows cd yes?
and do i have to take hdd out or just have that as my secondary boot item?

Re: pc turns off before POST
Yes the Windows DVD. It should boot from that, provided your boot order has the optical up first.
I'd remove the HDD completely, to ensure that any instability can be ruled out., or possibly swap it with a random good HDD
Re: pc turns off before POST
Try checking if any of the PSU cables are loose on components such as the GPU or MOBO. If not then check if the start switch cable is also in its slot properly.
Re: pc turns off before POST
im pretty sure all the psu cables are correct and in securely.
but i always get confused with the awkward power, reset cables, can never tell if they are correct place, do they have a positive and negative aswell? if so how do you tell?

Re: pc turns off before POST
No, there is no positive and negative end.. it should all be good... I had a similar problem.. i had 2 PSU slots on my GPU only put PSU wire in and it would start for 5 secs then stop. Im not sure about any other solutions apart from reconnecting the wires securely. Anyway.. Good luck :D hope i helped.
