Thermal paste on old thermal adhesive?

Specs: N/A, Intel centrino
Can I use thermal paste on the broken thermal adhesive boundary between my CPU and heat sink?

The story so far;
I am trying to get my old samsung xo5 working, and hopefully learn a bit about computer hardware in the process. I was taking it apart piece by piece, making notes, and in doing so I removed the heat sink from the mobo (I could have left it attached and still taken the mobo out, but you live and learn). It came away really easily and most of the adhesive stayed on the chip. I'm not planning on overclocking or anything like that, just getting the thing working to run puppy linux and use as a netbook. Please world, adorn me with your wisdom.

You need to completely clean of the old paste and re-apply:

Thanks, I'll try with meths. The stuff on my chip is solid, hard and dry at room temp. Is that normal for thermal paste?

What you are seeing is normal, for old, dried out thermal paste. This doesn't normally cause a problem , provided it is not disturbed. But once the CPU and heat sink has been separated the paste must be replaced.
