My main PC died on me a while ago, and I finally got round to having a tech look at it last week because I couldn't figure it our myself.
Basically what happened is that I stopped getting a signal to my monitor. Every time I would try to start it up, a box would pop up in the middle of the screen stating 'Video input – no signal'. I checked everything, made sure all the cords were firmly in place, cards firmly seated, etc, etc. Nothing. Motherboard seems to initiate okay, judging from the lights, power is running, CPU fan going, Video card fan is spinning – but no output. I even swapped monitors around, but it made no difference.
I took it to the tech who does the work for my wife's office, and he stated unequivocally that it's the video card at issue, even though he didn't have a PCI-e card to slot in for a test, nor did he have an appropriate PC handy to put my own video card in. I asked him how he could be so sure, and asked why there couldn't be a problem further back in the chain, such as the Mobo or the CPU. He stated that the Video card has it's own set of onboard data that it posts separate to the other components, and if the power was running to it and nothing was showing on screen then it had to be an issue with the card - he confirmed that the fan on the card was running by plugging it in, and as there was nothing at all showing on start up, the card it had to be! He took the 8800 GTS card, glanced at it, claimed it looked as if it had overheated – then tossed it in a nearby bin.
As some of you know, I did some hunting around with online vendors trying to figure out a replacement card, then came on here to ask for some follow up advice. Eventually I determined on the EVGA GTS 450 as something that would cover my needs, placed an order with Newegg, and waited with baited breath for it's arrival. My troubles would finally be over!
This afternoon it arrived, and guess what? As soon as I slotted it in and connected everything up – nothing! Just the same signal as before 'video input – no signal'! Do I go postal at this point, or throw the PC through the largest window I can find? Not only am out $150 for the card and tech fee, but a perfectly good card literally got trashed as well – I had no reason to doubt this guy, as his company has taken care of my wife's office computers for a while and they've had no complaints.
I quickly phoned the tech's place of work, only to be told by his boss that he wouldn't be available till Monday. I really needed the thing up and running for some specific work I need to do, but at best I'm probably at least a week away now from starting it up again, given that I probably have some other component to order in now.
Does anyone have any kind of clue what could be wrong if it's not the video card, or how I could go about trying to isolate the problem component? Any pointers would be much appreciated.
Thanks...........Tim
PS – one point. I have to use an adapter to plug my older LCD monitor into the video card. Could it have become defective and cause these kind of issues?
