Hey. Having some trouble with my computer. I've been updating this as I go along, to keep things clear in my mind as much as to ask for help. It's become quite long, hopefully it's sensibly formatted now. Testing method is now listed at the bottom, under subheading 'attempts'.
I have a working amd system, 7750be, ecs board, 1gb ddr2. I have a broken intel system, q9550, new p5q premium, 2x2gb ocz reaper. Each are using a pc p&c 860W. Excellent psu.
I believe one psu to be partially damaged. The other I assume is fine as it has suffered through no trauma.
I believe both sets of ram to be fine, as the suspect one passes memtest. I will test at 1066 when I can.
I assume both motherboards are fine, as one has given no problems and the other is new.
The graphics card is known to be working, tested on the amd system. Similarly the monitor works.
I think the q9550 is dead, and am running out of ideas for how to test this.
Background
This is after an rma of the motherboard, the previous one died with a burning electrical smell. I wanted to send the processor and ram along with it for rma, as burning electrics suggested to me that other components may have died. The supplier declined this request. I hope that the P5Q is not DOA, I'm reasonably sure it won't be.
Conclusions
I'm getting there, but very slowly. Mostly ruled out ram, as it runs fine at 800 at least. Gfx checked. Can't test cpu or motherboard. One psu known good, the other has a broken 8 pin line.
I think the processor is dead, but would like to test further before rma'ing it. Anyone sent one back direct to intel? Bought october last year, retail, so warranty should be good. Not lapped thankfully.
Thus far I have not managed to get the machine to post, the closest I've come is fans spinning and a pump working off a molex connector. No beeps at any point either, and the speaker is connected.
Attempt 1
Leds on motherboard are lit up as they should be
When pressing power, nothing occurs. No beeps, neither psu nor cpu fan spin.
This is with processor, ram, heatsink, psu, motherboard.
If ram is removed, no beeps.
If psu is started using a wire, psu fan spins.
Next, I've tried it with 1gb of generic ram, and it does better. Fans spin, no post. This points at the ram being faulty. However, I am currently running said 'faulty' ram in the machine I took the 1gb stick from. It passes half an hour of memtest at 800mhz (rated at 1066) and I can't test it at the higher speed in this box.
Attempt 2
This differs from the previous in that I'm using known-good ram, have connected a graphics card and a monitor.
All fans spin and lights as appropriate. No image on the screen. After 5 seconds approx the fans turn off briefly then spin up again, I think this is an oddity of my graphics card though as I've seen it before. No beeps.
Removed the ram. Still no beeps.
Attempt 3
Changed monitor cable. Fans no longer spin at all, but I'm certain I didn't change anything else. Removed card, and removed ram, no change. Computer is now back to doing nothing whatsoever when plugged in.
Attempt 4
Attached graphics card to secondary computer. Bit of a mission as it's water cooled and the amd computer isn't. Typing on the result now, so I'm going to rule out damaged graphics card. Again this is using the better/possibly damaged set of ram.
Attempt 5
Swapped psus over. My amd machine is now running quite happily, apparently it will run on either psu with no ill effects. Neither will run the intel system, but in different ways.This is with the known good ram.
PSU 1/ No life when power is pushed whatsoever. PSU 2/Lights on, fans spin, pump works, no post/beeps/life on screen. Propose that part of my power supply burnt out when the system died, and the amd system does not use this part. This is supported by the 4+4 pin cable working fine with the intel system, and either half of it working fine with the amd, but the 8 pin cable not working with the intel system. Credit to pc p&c, part of their psu is dead and the rest has kept right on going.

Q9550 [no means of testing]
Asus P5Q [just back from rma]
4gb ocz reaper [passed 30 mins memtest and normal use in secondary machine]
PC P&C 860W [one working fine, second has a broken 8 pin cable but otherwise looks good]
8800gt [tested and working in secondary machine]
What can I test further/what conclusions may I draw?
It's been a long night playing with this. I've sent ocuk a webnote to see what they suggest wrt rma.
