My Precision 670 refuses to boot and the post lights seem to indicate a VRM 0 failure. The machine fans are running full tilt on power up.
Can someone please point me to the location of this circuit on the board as I am happy to brandish the soldering iron on any duff parts. I have already noticed a couple of suspect looking 2200uF 63V capacitors in the region of the 2nd processor location, but only have 1 processor!
I did a Goggle search "VRM 0 failure dell precision 670" and came up with this,

Darn! Now that's unlucky!
I've emailed Tech Support to see if they can provide more technical details for a fix, but I'm not holding my breath...
Thanks for taking the time - it's much appreciated. At least I was on the right track!
Hi ! I have the same problem with my Dell 670 workstation. No motor or function from drives. first light green and two yellows. not sure what i need vrm bay empty!!
Thanks for the help!
The vrm0-module is a fixed part of the mainboard, only the vrm1-module can be relaced separately. You can replace the board,
but as many other users (including me) you are affected by Dell's decision to use low-end parts (condensators) on mainboards.
This leads to premature defects of this boards. Replacement boards are also equipped with this parts and will not last for a long time.
If you are a key-customer you can hope on fair-trading, if not (as me) you will not get any answer or help from Dell :-(
