PCIe cards, DVI cables, and analog monitors

Asus P5N32-SLI 680i
Intel ee6600 Core 2 Duo
2 GB OCZ SLI ready RAM (8500)
Antec PS (650watts etc)
BFG 8800gts 640MB Nvidia
also tried
PNY 7300 (small, doesn;'t have an onboard power coupler.)
Monitor is older MAG 19" with VGA and DVI-A connectors

DVI -D cable used on old system same monitor and BFG 6800GT Nvidia AGP.


I built the system.
Power up, fans, light all come on.

Monitor cannot detect a signal.

Unplugged video card - loud whine on power up.

Tried different slot - no go.
Tried Gigabyte MainBoard 965p - same symptoms.
Put in PNY 7300 - same symptoms.

I don't even see a setup menu, nor a Flash Page - nothing.

Reading about DVI cables - I think it may be the monitor cannot handle the signals? But then I read that DVI -D needs a DVI -D receptor. BUT I use a DVI -D cable with AGP card and DVI -A on the monitor. That's not supposed to work but It has for me. So I am not confident about the monitor/DVI approach - but cannot see another possibility ... except damaged CPU etc.

I never considered the monitor until after I went through all the difficult swapping out of hardware.

Monitor and cable works with older PC. (AGP)

Any thoughts? ( I did connect the 4 pronged ATX from the PSU to the MB)


Also, here are some concerns I had (fears)

1) Did I damage the processor when putting on a Zalman all copper fan/sink. I've assembled at least 5 PCs, and never saw a CPU fried nor damaged, but that Zalman seemed to "squash" down when mounting.

2) What symptoms show a fried motherboard? I see lights, fans, HDD - everything. BUT NO DISPLAY; monitor NEVER detects a signal.




I tried searching b4 posting. Soome things are close but no resolution posted after the questions.


This entire thing has left me feeling like a total boob. I really hope that a monitor that says it's digital or has DVI - D will work.

Has anyone built a PCIe system? Did you have troubles with the monitor and display? Like having to setup with a VGA connection, load OS etc etc and after Windows and PC are running - THEN power down and put a DVI - D cable on? It seems logical, but I NEVER HAD THIS ISSUE B4. I always take for granted that it will output to monitor.

Hope this is clear.
Many thanks.

So my DVI - D cable I used to connect to analog monitor DVI-A worked. Same cable with new 8800gts DVI-A out - DIDN'T work with new digital monitor. New DVI - D cable works.

ALmost as if the cable has a memory.

I have no clue, but it's working.

This is closed. Thanks.
