I hate PCs

[stevie lee]

when reinstalling windows due to corruption (error 0xc000021a) make sure that you actually select the correct hard drive to reinstall it back to.
unplug all the others if necessary, but make sure its the right one. and don't double click on the 'select which drive' list either, that proceeds with the install

just done a windows 10 fresh install from the November update ISO on USB, I just installed it, chose to not enter the cd key at the start of install. after 15 minutes it booted into windows and self activated.
then I noticed it was installed on top of the 1tb d:\stuff drive. where I put downloads and my mp3 collection. windows install hadn't deleted them, just added windows around them.

so off I went and installed windows 10 onto the correct drive this time.

booted it up and that activated aswell.

so I now have a dual boot windows 10 system, into 2 copies of windows 10 with the same cd key.
:woohoo:

need to wipe the boot data off the d drive now, but windows wont format the drive, says its a protected system drive. need to click around my backup drive to find the partition tools software.

anyway.

happy Monday everyone

I've been putting this off for about 2 months

EK Supremacy MX, started to lose about 1 drop of coolant every three days, was fine for many months before that.

Dreading the repair...



Noting that there's a 2500k under there, how am I going to fix this without spending £600?

I don't know, but I am looking forward to seeing the pics.

I don't know, but I am looking forward to seeing the pics.

So far, everything has gone as well as it could. I pulled out the CPU block and disassembled it without getting coolant everywhere or breaking anything.

I'm hoping it's a dodgy O-ring seal and nothing to do with these little cracks. Will investigate further tomorrow

Still no excuse to upgrade, yet.

[peterb]

Hmm, those cracks are a little worrying...

If a new O seal (presumably seats on the top surface?) doesn't fix it you might fin manage a fix with some PTFE tape on the threads, but otherwise I suspect it's new block time...

those look like the beginnings of failure cracks I'm afraid. often a combination of overtightening and internal pressure cycling leading to crack propagation at inherent casting defects. Since the hose screws inside the socket it pushes the cracks apart and then thermal cycling does its thing. You might be able to do a diy repair by getting a circular clip to go round the outside. it would need to be tight. maybe try one of the plumbing style ones with a ratchet band you tighten with a screw. Using plumbers tape will help but it is putting more pressure on the inside of the socket and risks growing this cracks even more. crimp the outside first IMO.


to be honest the best repair would probably be a brass ring heated and then quench-shrunk onto the socket but that would require some careful thought to get exactly the right size ring of the the right section properties and you would never get off again without cutting it.

I'm not sure a jubilee clip would apply enough external pressure, even if you could get it in place, however the band heat shrunk onto it might, but it would be a difficult repair.

As you say, those cracks propagate through over tightening, although that is often an understandable reaction to a leak! Hand tight is usually sufficient.

Out of all the spare parts EK carry for their CPU water blocks, the only thing they don't have are the damn tops... A suspiciously convenient omission is you ask me

The hose fitting was finger tight when I first fitted it and I haven't touched it before taking it apart last night. It started dripping a good few months after assembly at a manageable rate of 0.3 drip/day, I was properly in to Fallout 4 then and decided to keep the system running by placing a bit of kitchen roll under the leak. Rather than potentially making it worse by fiddling with anything, the comedic nightmare scenario of the entire hose popping off with a slight touch and coolant spraying from both ends came to mind.

I need this fixed within a week and I don't think returning this will bear any fruit because it's too easy to blame me for the damage. Guess I'll have to order a new block

EDIT: I just had a deja vu moment, then I remembered, ten years ago

[MrJim]

That takes me back...Tagan PSUs and green motherboards

I wonder if there was a casting fault in the block, and that it took a few months to show up?

As you say, probably nothing you can do about it now

lol nice. Tech moves on, but kitchen towel remains current

...After all that occasionally the thing doesn't come out of sleep, at which point she kind of gives up and uses her Chromebook

I know you must have checked this already, but is it a PSU compatibility issue? Older ones throw a fit when newer intel CPU's go into ultra low power sleep states - not that you'd enjoy a PSU change from the description of the case!

Nostalgia attack!

The days of inexpensive 2P boards and massively overclockable Xeon chips...

[SlayerMatt]

Sounds just like the time I built my first PC... after struggling for an hour to fit the components in (in hind sight, I should have bought a PSU with longer cables, even to this day its the bane of my life when I upgrade things, along with the case layout) the damn thing wouldn't boot, nearly had me in tears of frustration Luckily it was just a motherboard screw being slightly too tight causing a short. Well designed case will be a must when I decide to do a whole upgrade.

That said, I'll find out how much pain it is again when I get my hands on a new motherboard... The joys of a PC builder! xD

It shouldn't be, and I'm sure it got checked some time back before the motherboard got changed. I have a spare PC with a PSU that I can swap over, so that will happen at some point.

OTOH, that machine is using a Phenom II 965BE, I could swap the CPU out for something newer.

[peterb]

Leaving aside the possible manufacturing defect, it isn't a very clever design for the ports. That type of fitting should have a flat washer to seal against the flat surface.

An O seal has a round profile and wouldn't be that good a seal against a flat surface. There should really be a machined recess inside the port, which the O seal sits in, with the top of the seal slightly proud by about about 10 or 20 thou.

The fitting should also have a plain area between the shoulder of the fitting and the threaded portion

It would then screws in until the metal surfaces mate, slightly compressing the O seal against the sides of the recess and the plain part of the fitting, squashing it against both the internal surfaces.

That is how O seals are meant to work, and they improve the seal as the pressure of the liquid increases (as they are then compressed from the internal pressurised side).

Pffft. Geek.
