Hey.
Yesterday I replaced my old PSU and GPU with new (used) ones from friend. (before that I didn't thouched the PC for few weeks, but it worked fine),
and also installed new HDD because my old one did some problems.
I had generic PSU for few years (I don't have anything blown on the motherboard) and I replaced it with Corsair CX430 that been used for less then a year.
On the first startup the BIOS speaker beeped and showed this error: "processor thermal trip".
I use i5 760 non overclock (2.79GHz with boost to 3.33GHz) with intel stock cooler, and never had heating problem.
I thoughtthe cooler might moved or something during the install of the new CPU and GPU so I removed the cooler,
reapllied thermal paste (MX4) and installed it - and started the PC.
Everything was fine so I went out, but when I got home back I saw it was overheating and turned off.
I left it again during the night with speedfan (logging cores temp and fan speed, automatic fan speed) while the pc was downloading and installing BF3 from steam.
When I woke up I discovered werid problem -
it worked about 3.5 hours (3:30-7:00), higest core temp was 57c (avg was about 44c) (cpu fan was on 1700rpm, about 85%),
and at the last hour/hour and half the 4 cores was on 30-32c, then the log stoped (the PC turned off because overheating).
also noticed Core #4 is hotter then others sometimes. (In avg +2C, can get up to 7C diffrence)
Bios reset to defaults.
3.5 Hour of Prime 95 Small FFT test -
CPU Cores 69-72C
Fan up to 100%
Suddenly PC shut down - "Processor thermal trip"
Another Prime95 Blend test -
22:37-~6:00
CPU Cores 69-72C
Fan up to 100%
Suddenly PC shut down - "Processor thermal trip"

Just noticed that HWMonitor says max CPU freq (during converting some video) was:
Core #1 3723MHz
Core #2 3720MHz
Core #3 5164MHz
Core #4 9309MHz
Of course this is False reading, so I guess the problem is at the CPU/Motherboard?
What can cause this? old PSU damaged something (CPU/MB) or did the new PSU causing this?
Or is this something with the MB gone wrong?
i5 760 2.79GHz (Stock cooler)
Intel DH55pj
Corsair CX430 430W
4GB Ram
1TB Seagate
Sapphire Radeon 6770 1GB
Antec P280 Case
