Asus P5B-Deluxe
2GB 6400 OCZ Crossfire RAM
E6300 which was clocked at 3Ghz
7900 GT
Seasonic 500W PSU

I was away at work but apparently it crashed and froze in windows, after powering off and attempting to power on it would not start.

I've stripped it completely, full of dust and thats all gone. I've now got the mobo, cpu, memory and GFX plugged in on my desk. The blue LED on the mobo lights up when you plug the PSU in however when you press the power button nothing happens. I've checked its not the button btw :)

A couple of times yesterday it appeared to power up but i didnt get any VGA.

I know its hard to speculate but what do you think i should try swapping out? I dont have any spare parts for this computer so i'm going to have to buy some, hopefully somewhere like PChellworld will let me buy and return some parts if i dont end up needing them.
 
Hi have you reset the bios to defaults?
I would try that and see if it boots and if it does work on from there.
 
I followed the P5B instructions on that, removed battery, moved jumper position, put battery back and no difference still doesnt boot.
 
Sounds like a possible overheating.

I killed my old Athlon like, this, I took it to another house and had it set up, but their living room was absolutly roasting hot, and I forgot I had 7-volted my fans, went out left it on, came back and the house stank of burned CPU. Killed my CPU and board.
 
I've taken the PSU and tested it on another computer, that boots fine so I'm presuming that is functioning fine. (It is Seasonic too!)

I'm trying to boot up with just the motherboard and CPU which should at least power on. So now i think its down to the motherboard or the CPU. Which one do you think i should try replacing first?

I have been running the E6300@3Ghz for 14 months now and the computer is near enough on 24/7, do you think possibly the CPU has just given up? I dont think its necessarily over heating i have a tuniq tower and a lot of fans inside my case.
 
Will a motherboard such as a P5B-Deluxe power on without a CPU? Will it even power and beep or just not even power at all? I'm trying to workout whether its the CPU or motherboard.
 
I don't know about your mobo but most wont want to power on without ram :P

Have you tested your 7900GT as i have one and they are just so bad mine has failed 3 times lol and i am atm RMAin my 3rd 7900GT :(

do you have another system you can test your parts on?
 
Well my motherboard, cpu and RAM should boot up WITHOUT the gfx card so i'm making the presumption that the card is fine. It doesnt even boot without it so it cant be the gfx card.
 
did you ever get a fix on this as I have the same problem bougght a new PSU but zip nothing.


Below I pasted something that I put on a different site (thinkbroadband.co.uk)

My ex trusty PSU died today, was a bit strange for the past few weeks I been having problem powering PC if I unplugged or switched pcu off, if I just shut down PC normally it would power up first time.

If Unplugged then plugged back in I would have to hit the power switch 10 / 12 times before power came through.


It was a Thermaltake Pure power 680W which I have had for round 2- 3 years maybe longer.

I took it out and put it in sons PC where funny enough it would boot the PC up but nothing would show on monitor - and reset and on off button would not work (except to switch on not off)


So my question is three fold
a) Would this have only been a PSU fault
b)I'm looking to buy hiper 580w as I like the idea of less cables in box
c) Anyone else used this or have this? seems to have very good reviews by customers
and maybe ..
d) Could anything else be causing this problem as I put my sons one into my PC (his is only a bog standard 230w ..and it died after half booting PC). ..and so has the pc died now as well :( ...not been a good day
 
It could be the voltage or something is unstable or not at the right level. In which case some motherboards would be more susceptible? Not sure really :)
 
Have you tried booting up with some generic RAM in place of your existing RAM? I had similar issues with the P5B Deluxe and someone else on the forums suggested getting some generic RAM (runs at 1.8V) and try booting with that. It worked a charm. Hmmm... I'll see if I can find the thread for you.


EDIT: Ah here's the thread. netby had the solution. Considering how cheap some generic RAM is it might be worth trying in your case:
