Pc blowing my monitors?

if one monitor works, it's unlikely to be graphics card or windows.!!

youll need to upgrade your PSU for optimum wattage to run a decent one, that has 6 pin gfx power socket cable.
something like http://www.novatech.co.uk/products/components/powersupplies/cxs500w-uk.html
to power something like, http://www.overclockers.co.uk/showproduct.php?prodid=GX-286-AS&groupid=701&catid=1914&subcat=2392
Thanks, that's what i thought
But if im going to spend nearly £130 on a graphics card and PSU i might aswell just get an new pc with screen!
I thought if i can get a card for £20 then it might be worth trying to connect the monitors via DVI or HDMI or even use the VGA port onthe new card...0 -
From your testing it looks unlikely it's that the monitor doesn't work with the refresh rate or resolution. So, I suspect bad capacitors in the power supply, as this is a common cause for flat screen monitors and TVs turning on for only a moment before going blank. Even some quite new screens have bad capacitors. Often you can take the screen apart and easily see that the capacitors are bad because they're bulging and/or leaking.
Thanks
When you say the power supply do you mean the power cord that connects monitor to the wall?
Or are you talking about the power supply inside the actual monitor?0 -

Ok, it may be inside the monitor, or built in to a power 'brick' as people usually call them. If your monitor takes mains electricity directly in to it, then the power supply is inside the monitor. If however your monitor cable has a big square brick, like the ones laptop computers have, that will be the power supply.
Either way, regardless if it's made in the monitor or a power brick, your flat screen monitor will be running on some kind of low voltage DC. To make this from your 240V AC mains, there's a circuit that's basically rectifying (turning AC in to DC), reducing the voltage with a transformer and has some capacitors to smooth out the supply. I don't want to get too involved here, but the problem with turning AC in to DC is that AC swaps direction 50 times a second and DC for most consumer goods is ideally a steady flow of electricity in one direction, so capacitors that store and release electricity over time allow a kind of buffering to fill the gaps. When they go bad however, the monitor/TV tends to start up for a moment, but then the failed capacitor(s) can't supply enough to keep it running. So, it responds exactly like it would if you switched a working monitor off at the wall and back on again quickly - it goes in to standby mode. The capacitors responsible will invarably be the big electrolytic can types.
If your monitor is the type with a mains input, there will be an accessible circuit inside it to convert mains to low voltage DC - making it possible to inspect the capacitors and replace any which have failed. If there's a power brick, they tend to be sealed really well and your best option is to try using another that's known to work.0
