ughghgughggugh all this talk makes me not relish the next round of nonsense i have to do to this machine.

also sorry i can't be any help, but uh....hold on, let me just... *digs around*... I know those pom-poms were here somewhere....*disappears into junk pile*

hedgie:
The current build of my desktop is getting pretty long in the tooth (my laptop is fairly recent, and fairly powerful… for a portable device), and I'm becoming more and more inclined to scare up the funding for about the most powerful non-pro imac out there.  I have friends who work at Apple who are willing to let me use their employee discount, so I could get about $700 off.

pwhodges:
My wife's machine became unreliable recently - it would run fine, but took more and more goes to complete a boot.  Eventually it crashed while running.  I was able to keep it going for long enough to copy the disk.

When I looked at the motherboard, I noticed that some of the capacitors were swelling (the tops were slightly domed, not flat).  This is a failure I have come across in audio equipment; I recently fixed a favourite interface by replacing over a dozen capacitors, but in the case of a motherboard it just gets thrown out.  I recall a particular range of Dell machines that had this problem in a serious way, such that they would replace the motherboards for years after the supposed warranty ran out.

Anyway, peer at your capacitors...

Troubleshooting RAM/CPU/motherboard issues can be annoying without new parts on-hand to test things...

However, some retailers still have LGA1150 CPUs on hand - could be worth buying one from a place that's easy to return to, to try it out.

As far as capacitors, modern motherboards tend to use solid-state capacitors, and that looks like the case for this motherboard, so capacitor electrolyte failure is much less likely.

So I got bored, used ethylene alcohol 94% (fuckit) to clean the die & heatsink, used up my remaining heat compound aaaaaaaand

... SSDD  :cry:

I've recorded the POST-bootloop, so if anyone is willing to have a listen to what I mean by "three beeps", shoot me a pm and I'll give you a Googledrive link (is there smth like Imgur for vids? Don't you say youtube, I dare you.... ). Also have HDR-pics of the socket etc, if anyone feels competent to spot bent pins etc.
