Thank you for including me in your update to this problem.
You mention not receiving video but eveything is “green.”
I’m not sure of the age of your equipment but I’m sure you had to disassemble and reassemble everything, yes?
By chance, do any of the connectors, ports, adapters require pins? Like old VGA cables have adapters with pins. If a pin is missing, you might not get video or some other piece of hardware or peripheral may fail.
With the power off and the system unplugged, I suggest carefully reviewing all your connections to make sure all your pins (if any) are accounted for. If any are missing, examine the port it goes into to see if any have snapped off inside. (Carefully remove them if you can or check youtube to see if there are any DIY tricks for removing a snapped pin from a port.)
If a connection doesn’t use pins, make sure the connector itself still has enough metal to make contact inside the receiver. Possibly, a cable is so kinked that wiring inside is bad or broken.
Replace cabling that have missing pins or worn out connectors. …Or just replace all the old cables with new (or at least different) ones.
I hope that helps. i hope its something mundane like that! Best of luck to you and I hope you can bring your system back!
Hi, Thanks much for the response.
I forgot to mention that the HD IS spinning, but I don’t detect any other vibrations or sounds from it, as one normally would, when it is in the computer from my brother. When in my spare desktop, it seems to behave normally in all respects.
I tried all 3 DVI outputs today (2 on the graphics card, and one on the MB), but only have 1 DVI cable. It is brand new - I took it out of the package today. I also tried previously the VGA output (2 different cables, one with very little use) and the HDMI output (2 different cables, one new, one with little use) which come off the MB. All of the VGI and HDMI cables test ok on a different computer, feeding a different monitor.
There is also no audio from the system speaker, any of the 7.1 outputs, a USB speaker (if individually connected), or the headphone output.
ALL ports and connectors except the USB ports and those at the rear of the HD and DVD player are of the pin & socket type. All look fine including internal connections / connectors. And all have been reseated. I’ve not done a conductor by conductor check of internal cabling, but in the case of the video that would not apply anyway, as all ports are directly on the MB or video card.
This is just “bizarre”, given that the machine was evidently working when my brother to had move out to get supervised care, and other files had dates on them in the weeks and months earlier. Crash report files are all dated much earlier. A couple weeks after he moved out, my brother was dead, and a couple weeks later we transported the machine here, to my home. (I did not try to run it at his place.) Something inside could have jostled free when we moved the machine, but I can’t imagine what else to check, except the CPU to MB connections, and it seems VERY unlikely there is a problem there, given the machine working earlier, and the very secure appearing mounting.
I tend to also think “something mundane”, but, I am stumped! It is almost as if the BIOS (or UEFI) has simply disappeared.
