Help please

[Jay boy]

My ps2 chipped with an NH3 is not working ever since I brought it to a friends house. What I get is a 5 second extra of the cd tray coming out after pressing the eject button when in standby mode, I also hear a louder noise when starting up, like a fan. Anyone know what could be the problem? 39001 is the version number making it a v7, I would really appreciate if anyone can solve this, please note that I have no experience in chipping, nor opening the ps2, but if I must as long as it is a simple job, I will.
