hi does a scratch on the motherboard close to the gpu cause no video problems or most likely caused by the heat sinks and thermal paste that also causes known rrod problems, was also advertised on ebay with a rrod problem
your post makes minimal sense. a video fault is common with xbox 360's, as is the RROD fault. generally its caused by the excessive heat and the poor ventilation and fans inside the units. i don't know if you own this unit, or if you're considering purchasing it. but if you do own it and want it fixed a company i know of is called beetronix in sydney.
if theres a scratch on the motherboard, dont buy it if your looking for a 360. unless you know someone with a spare motherboard and knows how to put it in.
you can buy them now for 200 bucks these days for a brand new arcade..petty change really... dont buy used not worth it these days..
If a packet hits a pocket on a socket on a port, And the bus is interrupted as a very last resort, And the address of the memory makes your floppy disk abort, Then the socket packet pocket has an error to report! If your cursor finds a menu item followed by a dash, And the double-clicking icon puts your window in the trash, And your data is corrupted 'cause the index doesn't hash, Then your situation's hopeless, and your system's gonna crash! If the above doesn't help with your computer troubles, perhaps this will. If the label on the cable on the table at your house, Says the network is connected to the button on your mouse, But your packets want to tunnel on another protocol, That's repeatedly rejected by the printer down the hall. And your screen is all distorted by the side effects of gauss So your icons in the window are as wavy as a souse, Then you may as well reboot and go out with a bang, 'Cause as sure as I'm a poet, the sucker's gonna hang! When the copy of your floppy's getting sloppy on the disk, And the microcode instructions cause unnecessary risc, Then you have to flash your memory and you'll want to RAM your ROM. Quickly turn off the computer and be sure to tell your mom!
