Can anybody help or advise please.
I switched on my PC yesterday and I found my graphics kept on cuttin
in and out.
The screen would go black and then click back on again and this kep
happening. When it did settle, everytime I clicked on the screen, i
would cut in and out again.
I have a 256Mb GeForce FX5600XT
I reinstalled the driver and then installed the latest driver fro
Nvidia. Nothing changed.
I cheched all the normal settings in display and refresh rate and the
were as normal.

I then replaced my graphics card with one that had been taken out of m
sons PC on a recent upgrade which I knew was working ok
This was a 128Mb GeForce FX5200.
Again nothing changed.
I visually checked for anything I could see on the motherboard. I coul
not see any dirty or loose contacts.

I then decided that I would re-format the drive and reinstall th
O/system. I found that the screens froze on reinstallation when I ha
either the 256Mb or 128Mb cards in.
I found an old card in the cupboard a 32Mb GeForce MX 100 and thi
allowed me to reinstall the O/system. I have tried to get the 256 an
128 cards to operate and they are exactly the same..

My question is to ask if this sounds like a motherboard problem or i
not, what else can I do or check to find the problem.

My PC is a Pentium IV 3.06 on a ASRock P4VT8 motherboard with 1Gb o
dimm memory
 
Did you check the monitor and its cable? If hte same problem exhibited
itself with a different graphics card, it could point to the monitor.
 
This is where an ancient PCI graphics card kept in that box of bits comes in
handy.
 
Hi Cari,
Thanks for your help.
I have checked using another monitor and just to be certain another
cable.
Unfortunately still the same. As a last resort I have the PC in bits,
the motherboard is out and I am giving everything, particularly the AGP
slot a good looking at. Let you know how I go on.
 
Just to conclude,
I could not identify what was wrong and ended up getting a ne
motherboard and everything is back to normal (after a lot o
re-installing).
Yesterday whilst I had all the bits and pieces all aver the desk, m
13yr old son commented on hearing a "pop" from the back of the CPU o
the evening prior to my PC's demise. Although it must have certainl
run on for the remainder of the evening, I now conclude that somethin
on the MB must have blown.
Thanks for your hel
 
Sounds like a condenser went bang. Not common (you'll be glad to know) but
it happens sometimes. Always remember to use a power strip with voltage
protection to connect the PC to A/C power, as it tends to be power related.
Power spikes may not hurt 'normal' applicances but can be deadly to PCs.
