"A possible VRM 1 failure has occurred"
VRM stands for Voltage Regulator Module.
It regulates Voltage for the Processor.
The Processor MUST have a steady, 'clean', supply of Voltage; and it MUST be kept within the tight voltage range, for the Processor.
Too little, or too much; and the Processor turns off. (BIOS turns it off)
Your motherboard supports two Processors.
1) Processor (CPU_0) Zero which is in the middle of the motherboard, next to the PCI Express x16 slot;
2) and Processor (CPU_1) One, which is next to it.
The VRM 1 has failed. Needs to be replaced.

VRM's used are interchangeable.
IMHO you can remove Processor 1 (CPU_1), and it's VRM, and still use the computer; albiet slower though.
For additional questions please post in a Comment.

Thanks, I have changed the VRM though and this still does not solve it, where is the VRM located for the primary chip?
Primary chip? We talking the motherboard chipset? And more specifically, the Northbridge chip of the motherboard chipset? That's the capacitors surrounding the Northbridge chip. The Northbridge chip is by CPU_1 (Processor 1) Large black meat tendorizer looking Heatsink, sits on top of the Northbridge chip. The Solid Polymer(?) Capacitors, and the Radial Aluminum Electrolytic Capacitors.http://www.ebay.com/itm/Dell-Precision-6... Solids have a blue mark on one side, on the Top. Radial Aluminum Electrolytics have an X shape on top, and a black plastic sleeve. They are in the Motherboard Voltage Regulator Circuit,http://www.hardwaresecrets.com/article/6... See any bad 'caps'?http://capacitorlab.com/visible-failures...http://www.youtube.com/watch?v=Lut7MX5Dd...
Tenderizer. VRM's aren't used anymore to my knowledge. Old technology. Part of what the motherboard voltage regulator circuit does; is to regulate voltage for the Processor.
Clarification; "Part of what the motherboard voltage regulator circuit does; is to regulate voltage for the Processor." Should be; No separate Voltage Regulator Module is needed now, because the Processor is now handled by the Motherboard Voltage Regulator Circuit. Could I be wrong? Sure. I'm not Dr.Michio Kaku! lol! (Famous Theorist Physicist in String Line theory, and cool dude!))
Just curious about what you have found out.
Should also state, that it will NOT just be the capacitors close to the Processor. There will be ones involved in the motherboard voltage regulator circuit, AND for the Processor; that may be in outlying areas, and NOT close to the Processor. (Forgot to add that in first comment. Of course reading Hardwaresecrets article, would have cleared that up)

SOURCE: Dell Precision 670 throws "BIOS not installed!" message
i think this means that the harddrive needs to be refoarmated as the bios sees no logical drive in which the boot.ini file resides
SOURCE: Dell Precision 670 6 long beeps on post no video but pc is on
Please consult this Dell link for general startup troubleshooting for your system., and this link will take you to the codes for the error lights and beeps.
Finally, here's a good article to help solve general startup problems and diagnose the possible cause.
I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.
If I've managed to answer your question or solve a problem, please take just a moment to rate this post....thanks!
SOURCE: Bios update for Dell Precision workstation 670
DONT EVER UPDATE BIOS....99.99% IT WILL MAKE UR PC A DUD....MFGS DONT MAKE NEW UPDATES FOR OLD BIOS...AS BIOS CHIPS ARE HARDWARE MFG SPECIFIC...IF U STILL WANT TO DO...U NEED TO BE 1000000% SURE OF WHAT BIOS IS IN UR MACHINE AND WHAT BIOS SOFTWARE IS INSIDE THAT.....EVEN I AS AN EXPERT DONT ATEMPT IT....AS ANY CHANGE TO BIOS IS DIFFICULT TO REVERSE....
writing in all caps amounts to shouting....
sorry i wrote it in capital....not ment to shout at u...
just warning u
