Over the last year or so my desktop computer has acted up quite a lot.Last year I was forced to do a costly upgrade which ended up giving me a decent computer.However it seems to be acting up,I was using onboard video until a few months ago so I bought a video card.Everything was fine until a couple of weeks ago when I woke up and turned my computer on as normal,only to have the monitor say 'no video input' which was what it said when the onboard video stopped working.So I sent my video card back and it was found to be non-faulty.
While I was waiting for the video card to arrive back,my brother told me he thought that perhaps my power supply couldn't handle the video card.So I bought a new power supply,but after having my dad (a qualified tech) install it and check over everything,there was still no luck.That was a couple of days ago and since then I've had my brother check over it with no luck it still says 'no video input'.What's even more painstaking is that not only is it not working but everyone is baffled as to what could actually be the cause of the problem.The monitor was thought to be the problem as it's slighty temperamental but I have been using it with my laptop.Although since plugging the monitor back into my desktop it hasn't worked the same with my laptop.
Another thing we thought it was,was overheating.However my case has the temperature on the front of it and when I turned it on the other night (which was a hot night) the highest it got was 27 Degrees Celcius.
So I guess my main concern at this point is finding the cause of the problem.It's good to have my laptop for back-up to allow me to keep up with emails etc.But my laptop is far slower than my desktop and not only that but I can't access any of my important documents etc.So any help will be extremely appreciated.
Thanks
