Dead PC

It's telling you there is a CPU Fan error. That could be the fans, or the pump which counts as a fan in that respect.

The 700W PSU probably got it to boot because it has less protections/other reason.

Refer to my previous post for troubleshooting that.

Is the grinding noise coming from the GPU or the CPU socket area?
 
the noise seemed to be from the gpu which is back in the other pc along with the other psu, that pc is ok
guess something was not plugged in on the dead pc when the old psu was used.

the spare psu when fitted got me to the post screen and showed the cpu temp heading towards too hot, so it was shut down

so my choices seem to be to get the psu replaced, or get a cheap cooler for £40 or so.

The puzzle is that I got a good airflow from the cpu cooler when it was being powered by what I think is a dead psu (the 1000Watt one that came with the pc) the fans only pumped for a few seconds before power dropping, yet the old psu could probably have booted the pc, but the cpu would have fried

Yeah, I watched the vid and heard you say the fans were working but it sounds as if the pump is dead which would explain why the heat kept rising anyway.

I'm not sure how PSU safety mechanisms work in relation to fan/pump headers but I can tell you I'm familiar with systems refusing to start up because of a damaged GPU, and then when the (good) PSU is replaced with a crappy one with less protection features, it can then start up and the GPU begin to smoke. That happened to me once. I thought oh it's started so it was the PSU.... but then the GPU started smoking. It might be the same scenario here. That's all I can offer. End of the day it might still be a PSU issue but from what you describe I'm leaning to failed cooler pump.
 
the original GPU has not been used, the one in use was from the old gaming pc, figured it would need less power than the titan.

it got put back in the old gaming pc along with the lower powered psu. that pc was working fine with good temps. had it online for a few hours after putting it all back together

the video was of the original psu, it never booted to post.

the photo of the pc at post was the gaming psu, but there was no power to the cpu pump and so did not boot it for long as it would have cooked it
the video of the gpu and cpu fans going for a few secs was the original psu that never got to post.

a failed cooler pump is a possibility, just need to work out how to get the top section of the case off as the twin radiator would need to be removed.
I could buy another AIO cpu cooler and if I find it is not the issue, then use that for a second pc to be a basic pc for general browsing and films etc, but would water cool that as well.

the gpu cooling grill was almost but not quite full of fluff and dust that looked ok from the outside and looking thru the fan.

sent a staff member a pm as well as the original thread got hidden a few years ago.

the old psu is a OCZ StealthXStream2 700w Silent ATX2 Power Supply 80PLUS, but thanks for taking the time to reply :)

put the test psu into the dead pc and followed the advice from Ohlawll about a sata lead round the back of the pc that powers the cpu cooler.

booted ok, then tried more memory and it did not like it until all the memory removed and back to a single stick

i did have a load of error codes made harder to read as the pc is upside down and on the side.

added a network cable and copied spreadsheets and bookmarks to a usb drive on the work's pc.

I suspect that the PSU is the main issue and will have to test the ram slots on tuesday

never really noticed led codes before and when all the ram was in the machine refused to boot, so other issues as well,

The psu should be covered under the 10 year warranty, possible the ram as well

put the gaming psu into the old gaming pc, booted ok with the fans all working

so looks like a new cpu and a motherboard are needed.

not easy to replace either and 6 years is not too bad,

will make another post in a better location as really need all the ram slots away from where the gpu fan sits (next to the connections side as it blocks 1 slot.

would also like more ram, but maybe in a few stages
 
changed a few things around on the weekend, nothing booted, but have had the cpu cooler working ok

this included removing, cleaning and replacing the cpu block with fresh TP

CPU AMD Athlon 64 X2 6000+ 32 °C Windsor 90nm Technology
RAM 4.00GB Dual-Channel DDR2 @ 374MHz (5-5-5-18)
Motherboard ASUSTeK Computer INC. M2A-VM HDMI (Socket AM2 ) 26 °C
Graphics 1023MB NVIDIA GeForce GTX 460 (Gigabyte) 30 °C

The current cpu socket is LGA 2011 and AM2 for the old pc

https://www.overclockers.co.uk/be-quiet-dark-rock-slim-cpu-cooler-120mm-hs-01g-bq.html

intention would be to test the pc with one of these and if I need to replace the cooler, will swap back to another water cooler and use this cooler in the am2 socket pc

so much for a reply, even if I changed the cpu cooler and it confirmed that the cpu was dead, not easy to find a new one and then I might find other issues

usage role has changed and a newish upgrade could be more effective.
 
been looking at the possible reasons for failure and dropped How long will a water cooling loop last? into google, out comes my cooler with an estimate of 5 years which is a bit less than the current age of the system, so now looking for fan and fin coolers for the cpu
 
the cpu has an AIO from corsair to a dual rad, the pc died about 6 years old and so figured time to get a fin and fan cooler that seems well rated :)

out of interest, when building the new pc, the cpu will only fit one way ? and is there an easy way to tell ?

Some will only fit one way, others have no shaping/grooves to them, just rectangular.
Even if they only fit one way, it's best to do it right first time, as you can easily bend pins doing it incorrectly and they can snap off when bending them back into position.

CPUs will have a gold triangle in one corner. Check the installation guide that comes with the motherboard to know which direction this needs to point in relation to the socket.
Some motherboards have sockets with a triangle symbol on them, so you can easily see which corner matches the gold triangle on the CPU.
