Help problem solving PC that won't boot please

How confident are you about the prospect of building outside of the case?

Plec · 4 Apr 2019 at 15:06

And what cooler are you using? - please say strapped on air...

Drewb · 4 Apr 2019 at 15:08

OK thanks, I am just putting the memory back then calling it a day.
I won't have time tomorrow to build out of the box so I'd best leave it until Monday. Could play with the switches if you think of anything.

I am OK about building outside the case, to make it easier, it would be best if I could do it on the floor beside the case with the PSU still installed. Cables are long enough.
Just checking the cooler, it's big and air cooled.

Alpenfohn, sorry no model visible.

Great an air cooler - will make things a lot easier testing outside of the case, and easier for you to extract mobo.

OK - I will aim for Monday for an outside the case build., are you around then?

Yes and no - depends how the rest of today goes.

I'll definitely be around either the morning or afternoon - no matter what. So, @Plec me when you're ready.

Will do and thanks.

Both Friday and Saturday I managed to get the PC to boot up after many attempts so I left it running all day then, and when not in use I was running Furmark or Prime95 constantly just to load gpu or cpu.
Sunday I could not get it to boot, nor this morning. When it is running it is healthy, it's just getting it to the bios that is the problem.
Going to strip it down and build outside the case now.

Hey @Drewb

Did you ever run memtest when the system booted (i can't remember)?

Drewb · 8 Apr 2019 at 09:38

No, I ran the windows memory test, which restarted the PC and reported no errors, I don't know how good that is.
I also tried two of the 4 sticks individually.

Yes, we've kinda eliminated a rogue dodgy stick causing the problem by alternating sticks - but couldn't remember if we had run a test on one of the rare occasions we got in.

The skeleton setup outside of the case still seems the next logical step, unfortunately.

How are things progressing @Drewb?

Drewb · 8 Apr 2019 at 11:18

OK all set up outside the case. Just the mobo and cpu with power, I had to leave the graphics card in situ as I can't get at the PCI express release clip (how are you supposed to get these big cards out again?) but left the gpu power cables unplugged.
I can see the mobo LED qcodes and would expect something other than 00 to show even without the graphics card. Have tried 5 or 6 times but always 00 just like when it was in the case.
Does this sound like the fault is in the mobo?

Drewb · 8 Apr 2019 at 11:19

The delay was me struggling to get the mobo ad cpu power cables off the board

Drewb · 8 Apr 2019 at 11:22

Sorry forgot to add also tried with graphics power cables inserted as well. No change.

Possibly, or even CPU and PSU - still not conclusive i'm afraid.

Any light remaining on?

Do you have one stick installed?

Drewb · 8 Apr 2019 at 11:29

No memory, I thought I would get a qcode to say pre memory failed that way and it wouldn't try to go any further.
I would have thought that when running furmark the PSU was under much more load than startup, is that not the case then?

Drewb · 8 Apr 2019 at 11:32

If I have to get a new mobo, I would go for mobo and cpu as I see ocuk don't do 2011 anymore. I will have a rethink as well as I don't play games on the PC anymore, long story but I had to give up about 18 months ago.
