Laptop wont boot after cleaning heatsink and fan

Out if ideas - sorry.

Will it even power the cd/dvd to try and boot from an XP disk?

Yes, I overlooked in recent readings the fact that two were involved... since there are other posts mixed together... you came in at the middle of another posting set.

That takes me back to suggesting you look for an infestation... Running HiJackThis in its latest incarnation....

But, I forget that you look for the most obvious, simple error first... and we have not done that well.

Re-think everything involved in network fix...

Failed routers that emit electrical stuff are not all that uncommon.

The solution to the problem will be found back there in that work you did...

Does the network device light up? Do any power adapters heat up?

Since you cleaned the fan and heatsink in both, something you did to both caused the problem... cleaning solution, cable change, power change.

What I have to do with cases like this is get a good night's sleep, and get away from the machine for two or three days... relaxation helps... Do not go back to a bad machine while frustrated, angry, or tired.

My guess is that the problem will reduce to simple things and you will have both repaired within a half hour.
