when I download from a particular website which does calculations and CONVERTS to a pdf     internet explorer breaks down on windows 7   on my old nec laptop XP it works okay and converts the pdf okay  but not on my windows 7


question.    is it due to programs on my computer making too much demand and breaking it down and would removing some programs fix the problem.

how do I find out which programs are causing it.?What is the app that converts the data to a PDF ? ?it breaks down on windows 7 before it gets to the pdf part of the process it doesn't access the website and do the calculation.  the program is one I wrote in conjunction with assistance from a PROGRAMMER. it is in perl.   I have the IMPRESSION my computer is not powerful enough to cope with the request.  on the Vista computer it reads the calculatrions and brings the output up on screen but does not process to pdf  I can print from screen to get the output.   The old NEC xp laptop does it all.

my thoughts are  is it something overworking my computer that causes it to BREAK down. if so where should I start looking.
If it's a Win7 PC it likely has more horsepower than the XP PC...
We need the site info and the name of the conversion software app to assist any further.
