Two dead MSI K7T266 v1.0 (MS-6380LE)

[Rainbow]

Got two of these boards:
1. Had 5 4700uF Lelon caps bulged and cracked. Replaced them but it does not work. VCore voltage is correct, 2.5V for chipset and DDR is present. BIOS is flashed (with the latest version), can't find any PCB damage. Everything heats up but nothing, no beeps, no POST codes. There are some Tayeh 1500uF and 1000uF caps but they're not bulged - even picked random ones and removed to test ESR - and they're OK.

2. This one has Nippon caps, no Lelons. The CPU starts, it even beeps with no memory. But when a memory is inserted, it stops at POST code D3.

The Northbridge could have got hosed on #1. Replace all the Tayeh around the CPU, VRM and Northbridge for a start - Tayeh are known to fail silently. Check the backup battery.

Check/replace the caps near the Northbridge and DIMM slots on #2. Check the backup battery.
