Hi, if you do wish to disassemble to clean it I have now found the service manual and also a Youtube video of doing so.
I also had chance now to read through the previous malware thread hence how I now know the model number. (A lot of reading to do LOL)
Here is the manual as a PDF.

And here is a Youtube video of dismantling .
If at all unsure of the task, I do recommend leaving it to a qualified technician though. However that is the last resort here on G2G LOL
As for the System recovery options, I will ask you to wait for Phillpower2 to reply, I was only offering help for cleaning in case this is an overheating issue.
