The PC was left for a week unplugged from everything for storage, and is now back in my hands. The VGA port suffered what appears to be minor damage, but may be severe. However, the DVI-D port was left completely unharmed. I used a Lenovo DVI-D monitor that I inherited from work to test out the DVI-D port's functionality, and everything fit in like a charm, but still no signal. The monitor goes to "Power Save" after a few seconds (which is normal it seems for monitors to do) but I don't understand why it would do this as this is the same functioning PC I had before with one less port which is the VGA. I figured that in the past my monitor needed me to use the keyboard and mouse to provide a signal, however, my keyboards and mice do not function properly on the computer. With the exception of the mouse, I am using the same keyboard as before, and still the keyboard does not light up or function as far as I know, because there's no signal on my monitor. Ugh, what a hassle, but I recall a similar problem when I built the computer, which was that I had no monitor signal and nothing seemed to work to get it to have a signal. Sadly I do not recall the solution to this problem so I come to you guys.
Let's go over what I have done to try and solve this in summary (I will update this as we go along):
- I used a DVI-D monitor rather than a VGA as the VGA port is slightly bent and had no signal either.
- I tried using my keyboard (same as before) and mouse (new one) to get a signal.
- I checked all power connections coming from my PSU to everything else.
- I reset the BIOS by resetting the CMOS battery in place.
- I took out the RAM and put it back where it was. (as a random check)
- Tested the keyboard and mouse on this computer, which installed the drivers correctly and worked.
To me this sounds like a USB port problem as the monitors typically require any sort of input into the computer to provide a video signal. I have also switched around a USB cable into different pin slots to see if that might work, and I believe this may be the problem but I have run tests with it in both pins. I don't know how I dealt with this last time. Everything is secure as far as cables go I assure you.
Please take time and help me as I have an upcoming editing project to work on and this computer does not have the programs necessary, nor the speed.
