I have a friend who is willing to sell me his E74 error xbox for a real good price. What are the chances that I can fix it? What exactly is a E74 error and how can i fix it?

I've fixed 3 of them with that error myself. You need to open it up, swap out the tim on the gpu and then overheat the xbox so it resets. Then power it back up after it cools and it will be gone for a while. It could come back though. I have one that has been working for over a year though. One I sold, and the other is dead completely now.

Yeah I just saw a video on how to do this. I guess its just like baking a graphics card. It could go either way.

You can do what SeanWebster said below, but the overheating it part can be quite dangerous to the other components on the motherboard. I fixed Xbox 360s for over 4 years, and I can't tell you how many came to me fried because of attempting to fix it like that. The E74 error is a GPU error, that usually is caused by a cold solder joint under the GPU. What SeanWebster is talking about resetting it, the overheating actually melts the solder under the chip and fixes the fault, but causes more damage to other components.

What I suggest is this:

Take it apart, and make sure to clean all the dust in the system, remove the heatsinks for both the CPU and GPU, and clean all the thermal paste off with at least 90% alcohol. Once both dies are clean and shiny, get a heat gun, and set it to about 400F, or "low" setting. What you are going to do then is lay the board down on a flat surface, and start heating the board. You want to do this evenly by moving around the heat gun. Make sure you don't go any closer than an inch, I'd say two inches for safety. Do this for about one minute or two. Then, hold the heat gun above the GPU die, two inches above, and heat the die for about 3 minutes total, make sure to move the heatgun in small circles around the die every 30 seconds or so. The GPU die is the one that has the flat heatsink on it, newer models have a small heatpipe coming out of it. Now, LET THE BOARD COOL ON IT'S OWN! After about an hour, come back, apply fresh thermal paste, and put it all back together, turn it on and run the system for about 30 minutes, to make sure it's okay. Then, enjoy.

I always fixed systems with a reflow station, but this works well also, just requires more care.

Hm, i never had a E74 error before, mine was the rrod and what i did is dismantle the xbox360 unplug the fan connector and let it heat up for half an hour then replug back the connector and hold the power button. I let it run 24/24 and when the power shut off because of a storm or whatever i just restart it normally, sometimes it work and if it dont i just repeat the process, i restarted it about 6-7 times from now.

I wish I had a reflow station. That would be fun!
