I was giving a Dell Touchscreen Inspirion One 2205 ?All-In-One several years ago. It initially had a problem where if the computer was turned off it wouldn't turn back on. I found a workaround by removing the CMOS battery and memory... then it would boot up just fine... at least until its turned off again. So naturally I would just put it to sleep every night to avoid it. One day it turns off and refuses to turn back on. I try all of my tricks and still nothing. After some research I found that other people with the same model noticed the video chip was over heated due to the poor Heatsink/Fan design. Solution? Remove the motherboard and bake it in the oven or use a heatgun on the GPU I'm not about to bake the motherboard because it would melt a lot of plastic connectors. so my daughter and I took the computer apart, removed the motherboard and I used a heat gun on it. 10 seconds intervals on low and about 1 inch away from the GPU Slapped it all back together and BAM! booted up with the Dell screen! yeah... see how long this will keep... I also blew out a bunch of dust and used some Arctic Silver on the CPU and GPU.
