    You don't need to replace TIM unless the cured bond has been broken. You actually needlessly risk destroying the devices via ESD or other mishandling.

    I saw in a you tube video on how to apply TIM where it was suggested to apply TIM on the smaller heat sink as well.

    I just happened to brake the bond between the GPU and heat sink on graphic card.

    Yes, if the bond is broken, you need to replace the TIM on other heat sinks too. And since you "just happened" to break the bond on the GPU, then you need to clean the mating surfaces and apply a fresh new layer there too.

    In the final working hours when the old conventional PSU fan had died and was it self over heated the system board also went through a lot of over heating for about sixteen to twenty hours before the system was shut down. Can this affect the old TIM on the smaller heat sink. Will it be better if I replace that old TIM with new TIM on this smaller heat sink.

    No. Once again, you only need to replace old TIM IF the cured bond has been broken.

    Understand the computer would have shutdown on its own if it was getting critically hot - and that still would not have been near hot enough to hurt the existing TIM. Even the cheap, basic silicone grease has a operating range of temperatures up to 205°C (401°F). In fact, excessive heat will totally and permanently destroy your electronics before damaging the TIM.

    Remember, silicon is the stuff they make high temperature kitchen utensils, roll-up cookie sheets and muffin molds out of that you can put in 500°F ovens.

    Arctic Silver 5 functions just fine in sustained temps up to 130°C and peak temps up to 180°C - again well beyond the survivability of the electronics itself.

    So, unless you "just happened" to break the bond there too, leave it alone.

    Hi! now I need to know about the CMOS/BIOS battery. Mine is the original from the time I purchased the computer. In the manual it has been stated to replace with a CR2032 one. But the original one is already a CR2032 one. What should I do. The computer is five and a half years old and I have not used it for the past two years and a few months.

    CR2032 is a common battery. Pretty much every modern motherboard uses a CR2032.

    It is a battery, and as well as any battery, it degrades over time: you may check the relevant voltage, in order to see if it is still close to the rated one, but at any rate you should change it sometimes.
