You wont need a BIOS update, who told you that you do? Am I correct in assuming that this is a flat panel monitor as opposoed to a CRT monitor? If so, chances are there could be one of two things wrong. Either the refresh rate is incorrect or the monitor's power supply is on the blink (I had a similar problem with my own last week and had to buy a new power supply for it). Go into the monitor's settings and check the refresh rate. If it seems okay, check the monitor power supply otput voltage using a meter, they're usually about 12 volts output.

MAJ thankx its a TFT & the power cable ive got is a adapter type that fits multiple connections u know the type that has four pins like a cross this didnt come with the monitor so maybe ur correct, i was told to update the bios by a internet m8 ..thankx again

The refresh rate for a TFT is, normally, 60MHz, in contrast to a CRT monitor which requires a minimum of 85MHz to ensure that the majority of users won't be troubled by screen flicker.

Updating the Bios won't make a scrap of difference, but updating the graphics card/onboard graphics may well do so.

The PSU solution is another, perhaps less urgent, possibility.

Check the sticker on the monitor's power supply, perpetual motion, usually the output is about 12 Volts and 4 Amps. If you're using one of those universal 12 Volt power supplies, then usually they don't output more than about 2 Amps maximum, which isn't really enough to drive the monitor properly.

As Stuartli says, also check the graphics card's drivers.

The problem is your power supply. You will have to get one that suits your monitor. The one you are using does not put out the required amperage for the monitor.
