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.
Me, too! I can’t imagine what it could be. I’ve been surprised when a kinked cable was the problem I had on a computer long ago. I remember when a faulty font hiding in the Trash on a Mac brought it down.
Are you using one video monitor? Does the gaming unit have ports for more than one? If you have only one monitor but it can support more, try adding more monitors of the same or a comparable brand? …Or switch ports for the one you have? (Probably you’ve done that and I’ve overlooked it in the thread.)
Happy hunting and I hope you can get the issue resolved!
