|"If switching "Source" on the monitor is enough to get it to produce a picture then it is highly unlikely you have a software / driver issue going on here. It isn't a good idea to disconnect/re-connect the monitor from the graphics port while the system is running. You may damage the graphics on the PC by doing so.|
Q? Is the GPU in your system inbuilt in the motherboard or is it a discrete PCIe plug-in card?"
it is a desktop pc and the card is a separate PCIe card
"Have you tried disconnecting/reconnecting the power to the monitor after the blank screen bootup?"
i have turned the monitor on and off again with the power switch (it had the same effect as the source button)
"What happens if you disconnect the monitor from the PC and then turn on just the monitor power switch from cold. Do you get any On-screen-display message about "signal out of range" or "No Signal""
trying that after supper so i wont be sitting starring at it while waiting for it to cool
"How is the monitor connected to the PC? VGA Cable? DVI? HDMI?"
i use a VGA cable but my card came with a VGA to DVI connector so i use that
"Do you have access to another cable you could try?"
looking for one, i am pretty sure i have one just have to dig around
"Do you have access to another monitor you could try."
i have one but it is really old so i dont know that if it even works still
"Your symptoms indicate there is a poor connection somewhere that improves once the components have warmed up. That poor connection may be inside your PC, or in the cable where it connects at either the PC or monitor, or it may be inside the monitor. On the information so far available it isn't yet clear where the problem lies. Testing with other known good parts should help isolate it for you. Hopefully for your sake it is a flakey connection in the cable as that would be the cheapest/easiest to resolve."
yeah i hope it is just the cable but lets say it isnt and it is another part inside the pc, would i have to replace (for example) the mobo? or just the wiring?
forgot to ask but what could have caused this in the first place? because i havent changed anything in my pc's hardware specs or anything
