dvi losing signal to monitor

[noah]

ive got a glacier 6800nu and last night my monitor started reporting a loss of signal after being on for 5 mins or so. then the computer would not restart even pushing the restart button, i had to turn off the psu! this even happened when i was just in bios watching psu voltages to see if they were changing - which they werent.

it's been running fine since i took out the dvi cable and put the dsub/vga one back in.

the monitor is an iiyama e431
graphics are glacier 6800
cpu is a barton 2600
psu is an antec 380 watt that came with the sonata
ram is twinmos and crucial 1024mb

its a new install of winxp and nvidia 71.94 drivers. nothing is currently overclocked and hasnt been for sometime and the gfx are not softmodded.

anyone got any clues for me?

thanks

Its hardware fault - if it does it in the BIOS it can't be software so forget drivers etc.

I would also (at a guess) say its something to do with the DVI portion of the gfx card if everything is fine with the regular vga socket, rather than a prob with the monitor but only because of the additional problem you mentioned.

Is it possible to try the gfx card with a different DVI monitor? You just need to try and narrow down 100% which the broken component is, and get it fixed if under warranty.

i'll give another dvi monitor another go. i agree its sounds like hardware cos of the bios lark. shame tho, as ive just finished exams and want to play games again . does seem strange that its the dvi tho as i'd have thought there's less to go wrong with dvi than analogue as there's no conversion.

ah well its all from scan so hopefully they can help me out if its on the hardware side.

I think it could well be the screen; I had a similar problem with a Belinea 17" where the DVI socket wouldn't function above a couple of minutes but the D-Sub was fine. Nothing wrong with the graphics card, and everything wrong with the DVI input on the monitor. Bear in mind that the machine will think it's outputting via DVI even when the monitor fails, so it's entirely possible that the machine is still running, thinking it's outputting to DVI, but just doesn't appear to be working since the DVI's failed on the screen. That would track with the macine being fine on DSUB. In my case, Belinea swapped it (for an 18", no less!) and everything's been fine ever since.

hmmmn, well it seems the d-sub is doing the same thing occasionally now!

the thing is that the computer crashes too, i cant restart with ctrl alt del or with the reset button, onlyl by turning off the psu. confusing to say the least, i'll try anothedr monitor tomorrow but i havent got a spare gfx card
