Calling IT Boffins - Odd problem after upgrade ....

    Long story short.

    I bought upgrade hardware for myself - X48 Intel board, Quad Core Processor and proceeded to rebuild my wife's aging AMD 2800 PC with my previous bits (AMD4200)

    Effectively, I used a new drive and after a failed Ghost from my Raid drives, proceeded to reinstall XP.

    The only change to my previously running hardware was the removal of a Creative Sound card and the removal of my 8800GTX and the install of a new 8600GTS that I had bought for her PC.

    I installed XP, using my 20Inch LCD Monitor, directly connected to the DVI output of the 8600GTS. Install went perfect, no issues.

    I then moved the PC back to her desk and plugged in the 19inch CRT via the DVI output that I used, but needed to use a VGA plug to convert as the GFX card only has DVI output x 2.

    Monitor refuses to come on, no matter what I try.

    I tested the monitor with my laptop, VGA directly, no issues.

    Took the PC back to my desk. Works perfectly when connected via DVI direct.

    Anyone know why the CRT doesnt switch on when the PC boots? The BIOS screen doesnt show - so its not OS level, its before.

    I have plugged everything out - switched the monitor off - all of it, no idea.

    Its as if it doesnt like the DVI - VGA input. I also tested 1 other VGA / DVI Convertor - no change.

    Any ideas?

    Could be resolution. Are you seeing the boot up screen?

    Could be that the signal rate the card uses by default is a problem for the CRT??

    It's an odd one all right.

    Nope, no boot screen. I also reset the bios to fail safe values.

    So the pattern is, works on DVI (Digital) - will not work on VGA.

    Signal rate as in refresh rate? Nope - LCD only uses 60Hz which is no problem for the CRT. Its also still set to low resolution and nothing higher than 800x600 while on the LCD.

    If the connection is dvi-d it won't work with your crt.
    It has to be dvi-i.

    It has to be dvi-i.

    How do I know what version of DVI it is? Would the DVI to VGA adaptor that was supplied not take care of this?

    4 years roughly. Its a good monitor - 19inch flat screen AOC - 1600x1200.

    Do you think its 'too old' for the input?

    Ive used another adaptor that came with my 8800GTX - no difference. I did notice the pin out was different and ill go do some checking later again.

    I have a spare 17inch CRT - but its on loan to someone else and dont really want to spend on another LCD - will check - reading some support forums to get some ideas.

    Spent some time during lunch trying to get it sorted. Tried my analog input of my LCD - no change.

    Spoke to XFX support online - they are very good - havent seen this before but suspect it might be faulty card or incompatibility.

    Will try the card in my new PC tonight and see if it does the same. Have a loan card as a temporary measure at least - hope that works without issue.

    Its fixed, looked to be PSU or something to do with the power connectors. Dont know yet how I fixed it - but its sorted (for now).
