Failed connection to PC Monitor

I run on my other PC Windows98SE.
Suddenly this morning, after replacing a couple of memory sticks, the monitor is not showing anything when I switch on except "Not Connected"
I have tried one other monitor and two other graphic slots without any pictures coming up.
anybody any previous similar?
cheers
Eddie

Re: Failed connection to PC Monitor

That sounds like a motherboard problem - try putting the original memory back.

Re: Failed connection to PC Monitor

Did you discharge any static from yourself before opening case.... That can kill a PC dead, and thats from expierience.
You can fry the lot in a spark and not even notice!

Does the machine make any beeps as it starts? If not, do the fans start and does the HDD activity light flash as the machine starts- i.e. does it sound normal? Are you using a AGP or PCI-E graphics card or onboard VGA?

No beeps......fans start.......green light flashes on HDD but red light comes on briefly then stays out.......sounds normal........using PCI graphics card......also has onboard VGA.....

I simply leave the mains plugged in and touch the chassis. Not died so far Undecided

Have you reseated everything that goes in a connector.....cards, cables etc.
Quite often the act of inserting one thing unseats something else.
Are there any lights on the motherboard?

Yes I always carefully re-seat all cables and cards...but there are no lights on the motherboard...never ever seen them!!!

It's best if it is plugged in to switched socket so that you can turn the power off - the point being that the earth is still connected.

Re: Failed connection to PC Monitor

Yes, my PC's sit right alongside switched sockets which I always turn to off before any inside work.

Re: Failed connection to PC Monitor

So you have tried the PCI graphics card in different slots, and different monitors. Have you tried removing the card and running from the onboard graphics? If this works your PCI graphics card has had it.

Re: Failed connection to PC Monitor

Yes, I have 2 separate monitors.
One runs from the onboard graphics to an older monitor, the other from a new graphics card to a new flatscreen monitor and both methods produce the "not connected" notice.
I fear it is a problem with the HD.........

Re: Failed connection to PC Monitor

As far as I am aware you should still get POST messages with a failed HD.....or at least beeps from the BIOS.
Correct me if I'm wrong
