lines through videos, video card problem?

February 18, 2012 at 23:18:00
Specs: Windows 7, AMD / 3gb
anytime i watch a video i sometimes will get lines through it, either on the bottom or middle, I'm thinking video card. I've updated my drivers, uninstalled , reinstalled, I have even reformatted computer and reinstalled windows, happens in any browser and any OS. Also when i open a video at first the screen will get distorted with black and white lines then appear normal. Here's a pic of the lines you can see at the bottom, sometimes if i use fullscreen the lines will barely be visible, like this video. You guys tell me:

About the only things you have not tried that I can think of is the video card is going, or you have a power problem, either unclean power (cheap power supply, but that should show up in other ways) or your system is underpowered and you may need to replace the power supply with a better quality and slightly higher output. To be sure, list all of your specs including make and model of your MB, CPU, PS, Graphics, and anything that might have a significant current draw.

amd phenom II x3 black edition, 2.8ghz triple core, ultrafinity 500w ps, crappy 7200 gs, old 9800 gtx the fan is at full speed when i put it in. I actually just noticed something, well i think it happened before. My mb has a core unlocker so these lines show up and adobe crashes videos constantly when i have it on quad core, when i put it back to triple core, i do not get any lines and adobe is fine, i checked the same video i posted and its perfect now. So that means my power supply is underpowered right? One more core will consume that much more power?

Depending the exact power supply, how many 12 volt rails (one only is best), and how much amperage is on the 12 volt rail(s), it could very well be underpowered.
There is also the slim possibility that the fourth core was locked down because that core was faulty and could not be sold as a quad, but about the only way you will be able to be sure would be to try a better power supply.
To be more sure, please post the Amperage ratings on each of the different voltages as it is printed on the label of the power supply.
But the two power supplies I was able to find with that name both have dual 12 volt rails and inflated amperage on the 5V and 3.3V rails to inflate the overall wattage ratings. This is a trick used on cheaper power supplies to make them appear they have a higher rating then they otherwise would have and be able to sell them for more money. If they left the 5V &3.3V rails alone then it would probably be just a cheap 400W power supply and you would have passed up on it. It appears you just need to purchase a decent power supply and you should be fine. Look at this one:

Notice the 44Amps on the single 12Volt Rail, the 80% Bronze rating (efficiency), the active PFC, the solid state capacitors, and the 5 year warranty. Those are signs of a quality power supply.

i think the fourth core is fine, thats how these motherboards come and it is fairly new, plus it was working before i had the 9800gtx in. my 9800 gtx does say minimum amps of 24 on 12 volt rail, combined the p/s has 34a, but maybe it has to have 24 on one rail? here is the p/s i have:

Look at this quote from the advertisement:
"What is Dual Rail Technology?
Dual Rail Technology distributes power to components that require it the most. With Dedicated 12V Rail for the 2x2 Motherboard Connector, you get more power where you need it"
If it has "Dedicated one of the 12V Rails for the 2x2 Motherboard Connector" which is specifically for the CPU, then you only have one 16A or 18A connector available to power your graphics card. Even if the motherboard 'shares' a portion of this with the graphics card through the PCIe connector, this is not going to be really enough and may limit available Amperage to your CPU. Consider replacing it with the one above or one similar.
