3.3V rail is 4.08V Cant load Windows

MSI K8N Neo4-F socket 939

I have replaced the 5 bulging caps which were 6.3V 3300uf. All other caps on board look good and I detect no problems with my Mat Eleectronics ESR meter. The board boots to bios fine and shows the 3.3V rail is 4.08V. I checked it with 2 seperate power supplies.
The board will not load windows 7 or XP on a PATA or SATA drive. I cant boot to PE or a linux live disk. I can boot Hirens and run HDD Regenerator on the drives though.
It's a mystery. What controls the 3.3V rail????
All input is welcomed on how to proceed.
I have not replaced the 5 16V 1500uf because they seem fine.
