Gentlemen?,
Big trouble !
Dell Precision T5400 > 2X Xeon 5460 (4-core 3.16GHz), Quadro FX 4800 (1.5GB), 16GB ECC DDR2-667 RAM, WD RE4 500GB > Windows 7 Ultimate 64-bit
1. This computer was running normally at about 2AM this morning AutoCad, Sketchup, WordPerfect, Streaming radio.
Note A__ I had noticed that the RAM was running slightly hotter than usual lately. DDR-2 can be very hot- I've seen 93C when rendering. The situations in which RAM is usually about 73-75C were showing 79-80 C but the comparison is very casual and the temperatures were not a worry. The CPU's and Quadro FX 4800 were showing normal temperatures.
2. Computer at 6AM had no display > but was running and still streaming radio
3. At 6AM the power button light was solid amber, indicating a hardware fault. > If the system had gone into sleep mode, the power button light would indicate flashing amber
4. Pressed spacebar to wake up system > no video, but radio was still streaming, indicating the system had not gone into sleep mode properly
5. Tried restarting, and indicator lights showed system was booting
6. Monitor displayed "no signal"
7. Opened case and saw that all case fans, graphics card, hard drives, RAM fans were running. No unusual heat and in fact system was cooler than I would expect
8. Tried CNTL > ALT > DELETE restart > no response > did not shut down or restart
9. Hard shut down (power button)
10. Replaced Quadro FX 4800 (1.5GB) with Quadro FX 550 (128MB) < known good
11. Restarted, no video > Fault indicator lights 1,2,3 are solid amber, indicating (from manual) > "Routine system activity preceding video initialization"
Note B__ I noticed that the motherboard light was amber where I believe it should be green. However, I could not find this indication in the manual and >
Note C__ There are different fault light patterns to indicate graphic card failure, memory, board failure
12. Hard stop > Changed DVI connection on FX 550 to other port
13. Restart > no video > Fault indicators 1,2,3
14. Changed boot drive SATA connections to HD 2 (Seagate Barracuda 500GB) which is the backup drive and which is more or less a duplicate of the HD1 > restarted > no response, same error 1,2,3
15. Loaded Windows 7 Ultimate 64 bit installation disk > restarted > no video, no response restarted > same error 1,2,3
