okie, im sorting out my grand-dad's computer. he says he just turned on his computer one day and he got a 'No Input' signal from his monitor. i assumed it was just one of the connections round the back that got loose, so i went round casually to put them in straight Rolling Eyes

BUT - it wasnt this! Connections were fine. I even looked inside the computer to see if any of the connections were loose in there but no probs there either. sooo, i take the computer home and connect it to my bro's monitor - and it worked fine. so i thought basically that the monitor was fooked. but then, when i got a s/h monitor to replace the old one which didnt worked, i found out that this one didnt work with the computer either! then i tried my monitor (which defo does work) and it didnt work with it either! wtf! it only worked with this one particular monitor! Confused

basically, when i connect my bro's monitor to the computer, i can see the HDD light flash about 1 second after i turn the computer on. but it doesnt do this with any of the other monitors.

i tried to change graphics card to see if that changed anything, but again, no change; it only still worked with my bro's monitor. i also changed the power cables around but no change there either! Confused

can anyone shed some light onto this problem - its doing my brain in?! Sad

I think you may have a loose/faulty memory stick or there is a problem with the mother board which causes a freeze every now an then.

1) Check the connectivity of all the parts inside the computer
2) Try taking out a memory stick to see if it's a faulty one
3) Try going to bios and check if everything is in order and reset the factory defaults.

hey exon, thx for the reply.
1) ive checked all the parts, they all seem fine Smile
2) memory sticks seem fine too
3) cant get to bios; computer doesnt even boot up and it says 'no signal' on monitor!

could be perhaps a motherboard problem, although it not just a 'freeze every now and then' scenario. its specifically when i use certains monitors - it works fine every time when i use my bro's monitor! Confused

hmm, sounds strange. Try the following:

1. Remove the battery from the mobo for a few minutes.
or
2. I assume it is an AGP card you are using? If so, try to replace it with a PCI
card and see if that works.

and if that doesn't work, maybe try a monitor with dvi output. (if your card has the dvi input of course)

What OS is he running?
if it's an older OS (or maybe even with newer ones) it may not adapt to the computer's frequency ranges...
I'd suggets booting with a monitor that works, right click desktop, properties, settings, advanced, and in monitor, change the frequency to something like monitor default, or pick one that is listed as working for the monitor you wish to plug in.
You might also want to check the manufacturer's website for help and/or drivers of some sort.
