Hello everyone this is my issue
I have had my dell OptiPlex for a while and it’s been sitting around until I got the parts that I wanted for an upgrade that I wanted to do to it. I increased the ram to 8gb changed the power supply to a 280w from the original and installed a pcie Video card and when I start it up everything seems to start fine all the fans and lights begin as they normally have but no matter which cable I try on I cannot seem to get the OptiPlex to connect to the ASUS monitor. I have checked if the issue is with the monitor itself by trying it with my laptop and it worked perfectly so that rules the monitor out the problem must be with the desktop I have tried DVI,VGA,HDMI all to try and get the monitor to work but it won’t it shows “no signal” every single time and I have hit the limit on what I can do by myself to try and fix this issue, I have taken the pie video card out and tried using the integrated graphics card on vga into the monitor as it would normally I have tried dvi from the new video card to the monitor and the results are always the same “no signal” Below I will list the model number of the parts I have put into the OptiPlex and if anyone knows a possible cause of this issue please let me know it’s beginning to cause me a great deal of problems.
280 W dell OptiPlex xe sff power supply- Model-L280e-01
AMD Radeon HD 7470 1GB PCIe x16 Low Profile SFF Video Graphics Card
2 x 4 GB dell OptiPlex 780 sff ram
I also installed a second hard drive although not mounted I used a splitter cable from the power supply to split between the original hard drive and the new one. When I start the desktop the fan on the new video cards starts as though it’s working but no matter how I connect the OptiPlex to the monitor I do not get any signal.
Any suggestions would be greatly appreciated.
