Oh, I did the clean install though, but flickering lines are still there.
I think you really do need to get your power supply checked out. If you're not sure what its voltage/current/wattage parameters should be, check it out on Google.


As ever, we can give you more meaningful help if you post your full computer specs.

A clean install of which driver?

You have to provide us with at least the make/brand and model number of the PSU.

If it is a standard PSU it is probably only 250W. Standard replacement for a HP, Dell, Compaq low end PC.

Way too small.

The latest Nvidia Graphic Driver installer, it features "Clean Install" after you set Customize instead of Express.

We are aware of the clean install option from nVIDIA. I can assume you did not read and follow my suggestion about using DriverSweeper to uninstall old drivers?

Still need your PSU specs.

I think something is getting lost in translation here so I'll spell it out.

It is more likely to be your power supply than your graphics card, but we need you to confirm what make of power supply it is so we can determine its power rating.

You can upgrade all you like, but if your power supply unit is not man enough for what you throw at it, it's no better than a one-legged dwarf in a pole-vaulting contest.

this may sound daft,but have you tried switching the monitor off then on when it flickers, i use a 32" lfatscreen tv as a monitor and occasionally it flickers (not very often) i found that switching it off and on cleared the problem , i gave the same advice here
Screen Blinking/Flashing Continously
and it worked

Still won't work.

Can you read my first post of this thread then read my PC specs, so you'll understand?

Thanks for the PSU spec. It has a MAX of 19A for +12v and you GT440 needs a MIN of 22A, so you are under powering it. This may cause flickering and overheating in the GT440 and the PSU which would lower its output even more.
I would get a new PSU of at least 600W or what has a +12V rating of at least 28A to give some overhead for you. The hard drives use the same 12V too along with CD/DVD combo drives. The PSU you haver has 2 12V rails which means you have to balance the load on each one, a better choice is a single 12V rail and there's no balance issue.

I have confirmed that driver 275.xx is not a good one. You should still use driver sweeper to sweep the driver. The nVIDIA clean install leaves behind some registry entries and a few .dlls.

Here is a good PSU Corsair CX600 and is not too costly. It has active PFC and a single 12V rail with 40A. PFC is power factor correction which give a stable power source.
