iMac 27" a1312 not booting after dust removal
Hello guys i have a problem with my imac a1312 i didn't change any hardware, my imac was full of dust and it was overheating so i just cleaned it and removed the old heat conducting material between the cpu and the aluminium thing between the fan but when i got everything in place it wasn't booting, a small fan activity takes place every 5 seconds same as the mouse light and this keep on going like it is trying to boot.
I made sure that everything is connected right the flat cables and everything. .
Please help me with this problem i need my imac back :/
