'ello.

Having a few problems with my computer at the moment...

The power supply on the computer has been a bit tempermental for about a week or so... sometimes starting, sometimes not (which required you to unplug it from the wall, leave it for a few mins and then plug it back in) as well as getting fairly noisy.

On Sunday night, heard a bit of a pop/bang in my room in the middle of the night (computer wasn't on) - couldn't see anything out of the ordinary, so went back to sleep.

Got up yesterday morning to come to work, and tried to turn the computer on - when i pushed the power button, the green 'power' light lit up for a split second, then the computer just went dead (this is what it normally does when the power supply decides to be tempermental) but for the life of me i couldn't get it to come back after trying all the usual tricks... figured the power supply must've finally packed it in... no worries i thought.... bought a new one on the way home from work yesterday.... stripped the whole computer down last night to a bare case, gave everything a good dust/clean (it was about a year old, so a bit of dust in there) and rebuilt the computer from the ground up....

after i pulled the 'dead' power supply out, i found that it had a blown capacitor, as well as some other (what appears to be heat related) damage.

went to fire up the rebuilt computer after it was all done.... nothing...

thought i must have missed the power switch connection or something so i pulled it apart again and had a look - nope, everything as it should be....

the motherboard is getting power (as seen by the green indicator light on the board itself) but nothing at all happens when i push the power button....

i'm starting to think maybe when the power supply blew, it sent a big surge through the motherboard or something and fried that as well...

bah... anyone got a spare Socket 775 motherboard/cpu around that i could try swapping my board/cpu with to see if they're still good?

I'm looking to upgrade anyway, but i can't be assed spending a bit over $2.2k for the parts i want.... can anyone do me good prices on hardware? :( (PM me if you like)

The parts i'm after are mainly:

ASUS P5N32-SLI-SE-DELUXE Intel Dual Core 2 nFORCE4-SLI - Motherboard

Intel ATX E6600 CORE 2 DUO /2.4GHz/4MB CACHE/1066FSB/LGA775 - CPU

XFX GeForce 7900GS 256meg DDR3 DVI/TVO PCI-E 480Mhz - Video Card *** x 2 ***

DDR2 1G(1024MB) PC6400 800Mhz RAM(single stick) Kingmax - RAM (Doesn't have to be this brand, but roughly that speed/specs)

Power Supply CoolerMaster iGreenPower 600W SLI Ready (ATX)(RS-600-ASAA) - PSU (Doesn't have to be this PSU, something with similar specs though)

Thermaltake Armor VA8000SWA Silver Alloy Case with 430W (Doesn't have to be this case, just something around this size with good cooling etc)

Oh, also, this means i won't have 'net access except for at work (very, very limited) so if someone needs to reach me for something, feel free to contact my mobile.

I have seen this once or twice before and I have been able to ressurect the motherboard by replacing the blown caps, they are there to protect the rest of the motherboard, but you need to find the exact same type of cap to replace them with, but you can usually find them on old motherboards.

Jason, before spending money, locate the pins on the mobo for where the ATX power switch connects and try shorting them with a screwdriver and see if the board powers up, I have in a few cases seen ATX power switches fail and the symptoms are the same.

It is a long shot and a rare occurance, but certainly has to be worth a go.

Another and more likely problem is that a MOSFET or CAP has died on the mobo. But you never know. I assume you have replaced the PSU with a new one? I didn't see you specify that in your post above.

Yeah, gonna have a look for dead caps etc this afternoon when i get home. Will also try the thing with the ATX switch.

yeah, i did replace the PSU with a new one:

bought a new one on the way home from work yesterday.... stripped the whole computer down last night to a bare case, gave everything a good dust/clean (it was about a year old, so a bit of dust in there) and rebuilt the computer from the ground up....

Good luck with getting the latest Bahahah it will be old by the time you get home lol

Sad to say but they are not meant to last.

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.

      Looking for someone with a R34 front bar

      Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂

      new 1.5 LSD issues/concerns

      By Dose Pipe Sutututu · Posted

      Is this a brand new LSD? if so, have you followed any break/bed in procedure for it? Usually involves heaps of figure 8 patterns, a fluid flush.
