i am currently running a nvidia 7600gt on a pentium 4,1gb ram,epox motherboard with a 300watt p.s.u
howvever after enquiring with nvidia customer care,they advised me to increase my power supply,i knew the p.s.u was a bit on the low side,and i have managed to get my hands on a ctk 400watt psu
my question is "will changing the p.s.u affect the operating system or bios in any way",
the reason for the bigger psu is some of my games were stuttering using the smaller 300watt p.s.u so i presume the 7600gt was being starved of power so will the 400watt psu solve this problem!
cheers guys!

No...a larger power supply just provides more watts, and thus the ability to handle more devices needing power. Volts will not change, nor will amps.
I would go higher than 400..if possible.
You can never have too much money, or too many watts.

The OS nor the BIOS will have any idea you changed the power supply. All it does is supply voltages to work nothing else so nothing will be negatively affected.
Whether it will fix your problem largely depends on what the exact problem was to start with. Usually if a power supply isn't keeping up with system demands the system will shutdown. No power is sort of like pulling the plug! Sometimes system hangs can be caused by the powersupply. Since the video card you have does require some heafty power I think the change is warrantied but dont know that it will solve any issues.

For Bios, you should see no effect.
The only effect you should see with the OS is it might run better.
Sometimes when a power supply is over loaded you might see some "waviness" or barely visible lines in the picture, or even a picture which seems to move on your monitor from time to time for no reason. If you are seeing any oddness in your screen It may just go away with the new power supply.
The only possible negative I can think of to upgrading to a bigger power supply is you may hear more fan noise from the newer one depending on how it's built.

PSUs aren't like other system components where the OS or BIOS 'know' what make/model/etc you've got in there so it makes no difference. As long as the PSU supplies the juice needed you can swap them around as much as you like. Indeed, I stuck a new PSU in my machine at the weekend because I thought the fans in it were fcuked (turned out to be the bearings in the case fan making the noise, dammit) and it chugged on quite happily when I rebooted with the new PSU in there.

Changing the PSU is not something that either the BIOS or OS (Windows) will notice. However you may have been better getting a larger supply again. It could certainly help with the graphical stuttering you are having

Power supply source is really of importance. Your apprehensions are not unwarranted

Go ahead & change it.
Best to change it for the most powerful that will fit that you can afford.

go on replace with that power supply but that will consume more power.
