I am trying to sell my desktop PC to buy a laptop. My brother wanted my P4 3.2Ghz Northwood (478) so he swapped his 2.6Ghz Northwood (478) from his laptop into my computer - it has been working OK, until today my monitor won't seem to come on at all.

I have checked all the connections, etc.

It boots up OK, all fans are spinning, I hear it beep once when it starts up, which is normal, but nothing is showing on the screen...

Any idea's what could be causing this? I will try resetting the CMOS later on, when I find out how to do it!
 
Yes, the montor's light is on standby, but it won't come fully on. However, if I unplug the monitor from the GFX card and plug it back in, it does come on for a few seconds (this is normal) and say's something like "Power saving mode" - it usually does this though, so I don't think the monitor is the issue.
I will try it on another computer right now though.
 
OK. I just took out my GFX card (6800GT) and put in my old FX5200 and it works fine now....

I hope my 6800GT isn't dead! I will put it back in about an hour and see if it works, hopefully it was just a lose connector or something simple.
 
I just put the 6800GT back in and it doesn't work. The motherboard beeped 3 times, which means it can't detect the GFX card, or the GFX memory is bad.

I guess the only other thing it could be is a dodgy power connector. My FX5200 doesn't need a power connector, but the 6800GT does, so it could be that.

It's a bit of a coincidence that my brother was poking around with the PSU about a week ago with his sat nav, and two nights ago at 1am he was swapping my CPU, now less than 48 hours later it looks like my GFX is dead.

He blames me of course!

Damn this is annoying!!!
 
yeah yuou got another power connector to try or try your gfx in another macghine maybe the one were you got the other card from. if it dont work in that on then your gfx has gone :mad:
 
I unplugged the power connector to the 6800GT and it made a constant beep, so it seems power is getting to the card, but it just isn't working.

I will try it in the other computer and see what happeneds, but at the moment it looks like it's dead. :(
 
This is pretty damn strange.
Exactly the same thing happened to mine, to two of my friends' computers, and it seems, quite a few others judging by the posts on this forum alone, and all between Christmas Day and today.

for the cases of similar problems that I've noticed...

So, what's going on? Power surges because of the increased electricity usage over Christmas? There certainly was one when my PC blew, seeing as all the computers in my house restarted.

Sorry I can't help you with your problem anyway, at least maybe finding some reason behind it might help out.
 
have you tried safe mode, to make sure you graphic card hasnt set its resolution/refresh rate to be too high for your monitor
 
In what order do you turn things on.

Screen first then computer. Computer then screen. My screens work a lot better (ie don't sit there with no picture and little orange light) if I let the PC boot first at least past the video bios message then turn on the screens.
