righto guys, problem.. help is needed.

we just had a major storm over here, fork lightning, strong winds. the works.

I noticed the storm was comming, so i shut down both the gaming PC and the server, turned off the battery backup system. and unpluged everything from the wall sockets.

after the storm had passed, plugged everything back in, server starts up fine. gaming PC loops itself.

turn on -> motherboard check -> loop -> loop -> restart.

i can not see the motherbaord screen ( i.e GIGABYTE welcome screen). so i am guessing either the power supply has somehow shit itself.. or the motherboard has finally packed it in. any help would be appreciated

intel core 2 quad Q6600 2.66GHz

GIGABYTE GA-EP45 - UD3L

Quadleadtek GTX 470

1 x WD green 1TB HDD ( boot drive)

seagate 1.5TB HDD ( secondary/storage)

Thermaltake Qfan toughpower 850W PSU

Kingston HyperX DDR2 RAM ( speed unknown. cant remember)

ah usual with tradition. something screws up over xmas period. (last yer the great HDD failure of 2010)

explain loop - as this will help

i assume by motherboard check, it's posting then restarts

try pulling everything out except power and see if you get a post fail - no ram - if so mobo should be good - then start putting everything back 1 at a time - starting with ram - see if it post and stays on - then GPU - then HDD - then anything else

if it doesnt post or fail post it could be either mobo or PSU

just replaced the PSU with a backup i have ( 700W). and no change.

the loop is bascially restarting itself, i should of been more clearer. i cant get into the bios or boot menu because i cant get to the motherboard screen to press F12 / F9 to get bios/boot menu.

i'll try your suggestions tomorrow morning when i wake up :) thanks for the quick reply

If pulling things out one by one does not work then do this:

Take out the battery on the mobo, flush (press power etc), and reinstall & try again with just CPU, RAM and a HDD/SSD. No GPU or other PCI items.

yeah i didnt think to clear the CMOS. so i'll get stuck into it early tomorrow morning.

another motherboard is on order aswell as some new ram ( to suit DDR3 mobo). if i fix it before they arrive, i'll keep them as spares.

reset CMOS and tried to boot with 1 stick of RAM. the motherboard went past its self-test phase ( phase 1,2,3 LED's turned themselves off, before they would stay on).

so hooked up a HDD and GPU and i can now boot to windows. NFI what the problem was with it last night. probably that time of the month i imagine.

      Steps to DIY sanding car back ready for respray....

      By Murray_Calavera · Posted

      Did you panel beat the dents or have you tried to repair this only using filler?  Is your sanding block soft/flexible and is following the shape of the panel rather then just knocking down the high points?

      I haven't knocked them down yet. I think I made the repair more complex than it should have been. I had rock chips combined with waviness and dents and I tackled it all in one because it was near each other and just end up wasting a bunch of bog lol. I'll knock down those areas and see how I go. And yep what you are saying at the end is correct. I think I might be sanding the top of a steep hill then my sanding block falls into the dent and gets rid of the guidecoat if that makes sense. Though shouldnt unless I'm covering too big of an area with not a long enough block. I'll try something new and provide some updates. Getting there though! Thanks as always.

      Yeah makes sense, hard to comment on your situation without seeing what your doing. I was talking generally before, I would not be looking to randomly create low spots with a hammer to then have to fill them.  It's hard without seeing what your doing, it sounds like you are using the guide coat to identify low spots, as you're saying the panel is still wavy. I don't see how you're not ending up with patches of guide coat remaining in a wavy panel? Once the high spots are knocked down to the correct level, surely to have a wavy panel you need low spots. And those low spots would have guide coat still in them?

      So I'll put filler past the repair area a bit to make sure I don't miss anything. Then I'll block it until it's almost level, put the guidecoat, then keep blocking until it's gone. Then it's still wavy.  In regards to hitting the panel, I saw this video might give more context - Skip to 0:47 he knocks it down. But yeah I'm sanding until the guidecoat is gone then checking because otherwise my filler is still well above the bodyline. Unless what you're saying is I should put guidecoat around it early, surrounding the filler then stip once it's gone?

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      I refreshed the OEM injectors with the kit and connected it up. It now ideals okay even with the IACV removed. Driving still has the same cutoff issue like the 550cc injectors so the issue is somewhere else. I bought FPG's Fuel Pump Hanger. I will be installing it next, but it is not as straightforward as I thought it was with my limited wiring knowledge and no instruction on the specific model I purchased (FPG-089). I also got the incorrect billet clamp as I could not find info on the OEM sizing.
