Hi I'm not sure if this the right place to ask.
I have problem with my modified xbox360 slim... it was Jtagged.  My xbox even before I Jtag it, it always slow on the start up but then after Jtag it become worst.  Sometimes I need to wait for 10-15 minutes...
After few months then my xbox cannot be start after all even the power button are light up.

I've sent to a shop at lowyat... they said it because of the GPU and they charged me for RM110 and fix jtag RM170 total=RM280.  Then I went home and give it a run test... after like 15-30 minutes the xbox shutdown by itself and become red ring... I've tried a few more times and it still happen.  Now it happen right after the startup.

My question is:

is it the right price of xbox360 GPU?

What with the red ring? how to fix it?

THanks.  Hope someone really can help me.. I've spend so much money on it.... T_T
