I also got a Mac pro Xeon 64bit workstation it turns on fans are on there was a chime but nothing on my monitor at all. The monitor just goes to power saving mode . Need to know what to do.
Is this a good question?

allen Rosen, if you can give us more information on the model of your Mac Pro. In general the Quick Check for the no video goes like this:
1. Reseat all DIMMs. Refer to Memory Diagnostic LEDs.
2. Attach a known good and compatible DVI or Mini-DP monitor to computer’s video card. Verify video cables and connectors are free from defects (including bent pins). Verify the power booster cable is secure to the video card if required.
3. Power OFF/ON the display.
4. Verify the video card is supported in this computer. Previous model Mac Pro video cards may not be compatible. Cross reference the EEECode and GSX part number.
5. Reset RTC.
6. Confirm at least one known good and compatible memory DIMM is installed in the computer.
7. After power ON, verify front panel power/sleep LED illuminated, and not flashing any error sequences indicating a memory failure. Caps lock LED illuminates when press CapsLock key.
8. Verify the computer is alive by listening for the drive booting sounds. If not detected go to Power, but No Boot Quick Check.
9. Remove non essential peripheral cards
10. Reseat video card (and power boost cable if required) in the correct PCIe slot
11. Remove onboard backup battery.
For the deep dive on this, check these instructions:
1. Disconnect all internal drives.Attach a known good display to the video card. Power ON the computer and verify video is observed on the display.
Yes Video observed. Go to step 2.
No No video observed. Go to step 3.
2. Verify the video quality observed is OK
Yes Video quality OK. Go to step 5.
No Video has poor quality, e.g. dim, distorted, etc. Go to step 4.
3. Reset SMC and PRAM. Reseat memory, processor tray, video card. Verify video is observed.
Yes Video observed. Go to step 2.
No Move the video card into PCIe slot #2 to determine if backplane board PCIe slot #1 is defective. Retest.If video observed in PCIe slot #2, replace backplane board. If no video observed in PCIe slot#2, replace video card. Alternate: Go to step 7.
4. Reset SMC and PRAM. Reseat memory, processor tray, video card. Verify video quality observed is OK.
Yes Go to step 5.
No Replace video card. Alternate: Go to step 7.
5. Reconnect an internal boot drive. Allow the computer to boot (video software drivers will load). Verify video quality is OK
Yes Video quality observed is OK. Problem maybe with the customer display, or the customer display may not be compatible.
No Video quality problem evident after booting. Verify video card fan operating,and is not clogged with dust preventing adequate cooling.
Go to step 6.
6. Boot from known good and compatible Mac OS X. Verify video quality observed is OK.
Yes Video quality observed is OK.Problem isolated to software. Clean install the customer hard drive with known good compatible Mac OS X, i.e. use the media supplied with the computer.
No Move the video card into PCIe slot #2 to determine if backplane board PCIe slot #1 is defective. Retest.If video quality OK in PCIe slot #2, replace backplane board. If still poor quality in PCIe slot #2, replace video card.
7. For testing, 8-core computers require only one processor installed in socket A. For 8-core and quad-core computers, reseat processor in socket A.Verify video observed.
Yes Go to step 2.
No Go to step 8.
8. If 8-core computer, swap removed processor with processor currently in socket A and retest. Verify video is observed.
Yes Replace defective processor.
No Replace processor board.
