Okey I got the same problem and changing heatsink solve it but... Is there any point in replacing this mainboard for new one. On every new the same thing will happen. Is is something really bad that those bulbs melted a bit maybe they will always in some time because that are straight under this CPU retainer?
And maybe evaen brand new mobo can have melted those two solders couse of tight reatiner don't you think?

What type of heatsink did you switch to? I changed to another brand heatsink on mine and it still happened.

I am not convinced that the heatsink being too tight is a cause, or indeed a soldering problem.

I mean, sometimes a PC suffering from this problem can be booted up and powered off for weeks before it happens... I am more inclined to think it's some sort of BIOS issue where it doesn't always detect the CPU properly.

well right now I just didin't lock the intel heatsink just put it in retainer without locking those plastic arms (and strange is that then my CPU is even colder=)). But I'm going to change to Zalman heatsink. Also I don't know what to do with my mobo. Maybe it's better to sell it and buy Intel Desktop Bonanza D875PBZ-LK BOX Pro/1000 LAN ? I'm not overclocking my mobo so why not? Still don't know if I get new Asus p4c800-e deluxe I don't get flattened. Any pressure to these solder joints will cause them to flatten and expand over a trace.

Just take a look at this topic:
