Strange bootup

[GoNz0]

u got a mates machine to try the video card in, maybe even take your rig round to do some swaps and tests ?

unfortunately not, but when i do go home (im currently at uni) that is certainly an option

bumpity bump:

0.5 seconds after the button is pressed i hear the hard drives spinning up, then i hear the click which i assume means there fully spun up.(takes about 5 seconds)

5 seconds seems a long time to me (and I have a similar system). And I don't experience a click. But I can't see how that would effect the GFX, except possibly if it indicated a PSU issue.

Did you try booting with minimum system and see if the problem persists? Another thing, have you tried a 'blind' Del into BIOS and then Esc out - this does a warm reboot. Interesting to see whether that does the trick or whether it needs a proper reset.

Will try the warm reboot idea tonight

will also try the minimum system idea.

***UPDATE***

now when i turn on the pc the fan lights come on for a millisecond and i hear a short beep and the pc turns itself off?
anyone got any ideas? could it be the psu thats finally been shot?

also i want to add before this problem i was gaming on cod4 and the pc just turned completely off mid game.
however it booted up fine after that.

a few hours later this is the issue.



furthermore when i tried turning on the pc with no power to the gfx card, i hear one continous(1 sec) louder beep that normal

thats the 8800gtx's inbuilt siren saying i have no extra power, scared the crap out of me once !

so do you think the psu is to blame for the problems?

[GoNz0]

i honestly dont know, but i do know a 8800gtx has its own sounder when you forget to plug in the pcie cable, i think it boots irc but only in low power mode to stop it burning out your motherboard.

what happens if you take off the 24/20 pin motherboard cable and hotwire teh green cable near the middle to a surrounding black one ?

try it out the pc to start with, if it fires up with 1 fan connected then hook it up one by one to each componant that needs power and fire it up each time to see if any single componants causing the shutdown.

if it all works ok wihtout the motherboard you have it pinned down to psu or mobo, you can then try booting without ram and then cpu to see if it stay on

I think it could be the PSU that's at fault here. All you can do is try borrowing components somehow and swapping stuff in to try.

[r_j_k_p]

its ok atm. i built the pc on some cardboard and it worked fine.
then i re-put it into the case, all wired up and it worked as normal. Just one of those mysteries that will never be solved i guess.

put it down to a bad connection then m8
