Ok finally gonna sort this problem

Ok so in the 3-4 months ive had this pc, i have had a recurring problem - the pc won't boot 90% of the time, i really don't know why, first i thought it was psu, but same results with my perfect condition OCZ psu - then i thought RAM, but i tried it with brand new xms3's and still it refuses to boot, with a different gfx card, nothing, different hard drive, nope.

So its down to motherboard and cpu - (by wont boot, i mean all fans and lights etc come on, LCD poster says welcome then just starts ticking away with the time instead of booting, the power lights by each major component on motherboard aren't lit up, which is why i guess its not booting)

the way to fix this seems to be, turn off psu, remove and reseat all 4 ram sticks and my cpu and heatsink, once they are all back in it boots fine, but you have to admit this is a long winded way of starting my pc, not to mention a high risk of bending a cpu pin, so what should i do? is it cpu or motherboard?
How can i test? i would personally say motherboard as it doesnt seem to always transmit power to components to make it boot.

ideas?

Its the asus crosshair 790fx rog board, its not monitor, it literally boots nothing

and yes i normally get a single beep after post, which im not getting, and also the card revs its fan for about 2 seconds when its posting successfully

Bump

nkata - yea it works fine with stock and overclock the same, it just refuses to boot 90% of the time

overclock doesnt affect it

Yes, mentioned in original post about poster.

pv123 - Makes no difference, i tried booting from multiple harddrives and none at all - wont even post without a harddrive - i have tried booting with min components to no avail.

yeah i tried resetting cmos and bios loads, i updated it and downgraded several times, makes no difference, so im still saying board personally, any more comments? should i rma board?

Ok psu, when i ordered this it came with an OCuK crusade 850Watt, and i first thought that it was that because its a cheap psu, but with my trusty 650watt OCZ stealthstream its the same.

@ Operation, I removed battery and have used the clr_cmos jumper button which is integrated into the mobo, no affect sadly, and the same problems occurs with bare minimum plugged in, there must be some power transmission failure through the motherboard somewhere or somehow and i agree mnemonik, if it was my cpu it wouldnt boot at all, it seems that because i remove and reseat the cpu to allow it to boot, that somehow breaks any current left in motherboard? like static build up or something, i duno an rma seems worth it, but i dont want to be without my pc for a while, how long do rma's normally take?

belial8321 · 6 Apr 2011 at 19:16

and also could i just take my whole system into OC hq and get them to look at it there? and just wait to see what they say?

belial8321 · 6 Apr 2011 at 19:36

a standard call out pc repair man wouldnt have a clue i don't think, im an almost fully trained one myself (comptia A+) sadly i don't have facilities/spare parts to test and swap in and out with to route the problem

belial8321 · 6 Apr 2011 at 23:09

further idea's anyone before i consider rma?

belial8321 · 7 Apr 2011 at 00:56

Oh sorry thought i answered that, ok it basically doesnt work even with minimum hardware plugged in, i mean its booted at the moment, has been on for like 120 hours or something perfectly stable, mostly been brutalized by solid gaming since i booted it, has about 12 usb's in atm but they dont affect its boot at all, have tried it at bare basics, PSU, mobo, 1 ram stick, cpu and no video card to try and get a basic post using the lcd poster screen, doesnt affect it and still wont boot until i reseat cpu :s

belial8321 · 7 Apr 2011 at 01:09

sorry dustofnations half asleep here, OCCT and how do i view them? im so tired XD

belial8321 · 7 Apr 2011 at 01:09

what is OCCT* and how do i view voltages

belial8321 · 7 Apr 2011 at 01:12

oh ok a stress test app, still dont know about how to view psu voltages tho

belial8321 · 7 Apr 2011 at 01:25

ohh, OCCT shows voltages?
Cool, i shall do this asap as i have to go out now, thanks for help, check back here later and i will post results

belial8321 · 7 Apr 2011 at 12:58

I have checked all over for shorts, yes i do have standoffs

hehe
I built it on the motherboard box on several occasions, same problem still occurs, even after having checked the whole thing over for damage and shorts, i've even been over it with a maginifying glass, in case its something really dumb, like a tiny screw caught between capacitors that i dropped there or something, i will do the OCCT thing when i get back from work, thanks for the help

belial8321 · 8 Apr 2011 at 03:33

yes buchanan that is correct

belial8321 · 8 Apr 2011 at 03:33

i also have OCCT now and have done a few tests with it, what results do you guys want to see from it?

belial8321 · 8 Apr 2011 at 17:59

Guys if i can take my entire pc into oc uk, reckon they can sort it out for me, to save rmaing, as i cant be without it xD

belial8321 · 8 Apr 2011 at 22:05
