I've done a pc internals transplant - put my current motherboard/cpu/etc into new case with new power supply, and I've run into... some kind of tech issue that I just can't figure out.

 

The new system seems to power up but doesn't POST, not even speaker beeps (unless I turn it on without the ram installed) and I've reached the end of my enthusiast-level PC building skills. (I know I could probably get help on here, but I'm so utterly stressed out from other important stuff in my life right now that I just don't have the patience to troubleshoot it any more, after two days of hair-tearing frustration, and don't want to end up making a stupid mistake that ensures that's it's broken - right now it's only "mostly dead.")

 

I've put the old motherboard and cpu from my previous trip on the upgrade cycle into the old case, so I'm not totally without a pc (although doing anything much on it pegs the cpu ridiculously easily - it's an old Athlon II) and I've reassured myself that I'm not *totally* inept inside my electronics... but I still need to see if my transplanted machine can be saved.

 

Can anyone suggest a trustworthy company in Chch (ideally Riccarton-ish for ease of transport, but buses where necessary) where I could get it looked at?

 

(I'd caveat it again with "which won't cost the earth," but I haven't enough experience to be able to tell what are reasonable rates - feedback there would also be great.)

Maybe Global PC at Tower Junction. I have not used them for any PC repair myself, but they have managed to stay in business while many others have failed.

I'd first suggest reseat everything. Pull it out, plug it back in again. It sounds like you haven't added anything latest and greatest? Try the old power supply to isolate that?

Yep,but if its an old Athlon based upgrade, hourly rates might take over the value?

 

3 hours spent on an Audi costs the same as 3 hours spent on a Toyota Starlet!

Know its not the answers you want.

 

But since the only new thing is the power supply, Pull the video card and watch the HDDs for normal boot. Depending on brand, It may not be enough gusto.

I thought that and assumed (possibly incorrectly) that a new PS is bound to be better than the old (original)

Or a puss version :P

 

Just thinking of BIOS POST offload, one of the first things is video NVRAM check so it can output the rest of tests. But can come before or after initial RAM-OK check which made me think, CPU 4-pin missing? But that would do what it is doing now, but likely not respond to no ram. Of course multichannel sticks can test OK but still not fire up video out too if 1 is really bung.

The new power supply is a Silverstone 500W, and the machine it's powering is an AMD A8-6600K (I was using a Radeon R5 260X in there but I've transferred the video card into the old system in order to preserve my 2-monitor layout and to cut down on variables in the new case - the A8 motherboard has onboard video).

 

The Athlon II is the system I used to use before upgrading to the A8 a while back, and I've just put all the components from that old build (and the R5) into the old case that I've taken the A8 components out of.

 

I'll give Global PC a look, thanks.

A colleague had a similar issue, it turned out he had an accidental ground from the motherboard to the case.

Good point, thats easy to overlook . New motherboard may be shorting out on old metal mounting supports

Try....pull the board from the PC & test it on the workbench.
Have the very MINIMUM needed plugged in , no cables at all and start it by carefully shorting the 2 power on pins .

Fortunately somebody came to the rescue (hat tip to kiwipeter from here), and it's all up and running again after being disassembled, cleaned, and reassembled.

Good to hear! I've brought a video card back to life just by cleaning the contacts on the card with a  pencil eraser & the contacts on the card did not look dirty, maybe a little dull.
