When the paste dries!

My computer was working fine enough. All was going well for it. Suddenly it began to freeze without a warning. With the help of my friend I came to figure out the source of the problem - overheating of the CPU. Now there are a number of reasons that can trigger this particular problem. In my case the CPU was fine, so the culprit was most likely drying up of the heatsink compound that is present in between the CPU and the heatsink.
These are actually conductor that transfer the excess heat of the CPU to the heatsink which dissipates the heat using the fans. So all I had to do was apply a fresh coat of heatsink compound to the CPU top and also on the heatsink surface and I was set. My machine was fixed and the CPU was cooled.

Why does the paste dry up?
Well, actually in dry conditions or due to prolonged use, the paste dries up reducing to powder, when it gives way leaving the heatsink separated from the CPU. So the CPU heats pretty fast and there is a risk of component overheating, irreversible damage etc. So it is important to fix this issue as soon as possible. And that's what I did.

What are the symptoms?
Your system will freeze for no apparent reason. Simple. No error message should pop up as it is not a software issue. The CPU overheats and to protect it the BIOS freezes the system as a kind of warning.

What to do?
Just open up the cabinet, open the heatsink, apply the heatsink compound to the CPU surface and the heatsink surface and you should be fine. Refit the heatsink and the system should work fine.

Note : While applying the coat of paste on the CPU make sure you apply it evenly, and please only apply it to the external surface of the CPU only. You DON'T need to detach the CPU from the socket. Apply the paste where you will find a white powdery substance present.

Burhan Wani – The man and his mission

Burhan Wani – The man and his mission The death of a young ‘hero’? On the 8th of July, Burhan Muzaffar Wani died in the Valley of Kashmir. Thousands poured out on the streets to commemorate his services to the movement that he had come to symbolize of late. The relative calm of the region was shattered with curfews, killings and allegations of human rights abuses. His father was proud for the services his son had offered in the name of their faith, convinced that he would go to Heaven. Amidst all this, the romantic ideals of a young boy, just off his teens began to shake up the youth of the entire country, both in and beyond India. There is a lot of unrest in the Kashmir Valley recently, especially in the aftermath of the death, nay execution of Burhan. All of this is not unexpected in any way. In fact, this was foreseen. Even his glorification, his elevation to the status of a martyr in the service of Islam does not come as a surprise to me.

Letters, open and counters

In this Information age, the opinions of people are shaped by the discourse that happens in the media – the newspapers, the internet forums, the videos that are shot, the letters, open letters and counter letters. A vast majority of them are full of half-truths and that is not surprising as every side has skeletons to hide. The problem arises when a gullible population (read Indians) digest these printed words both offline and on as the ultimate Truth without question. Secondary sources and even imaginary accounts becomes Gospels to be used to shut anyone who dares to oppose the mainstream discourse.
The Quint has recently published an open letter by a veteran soldier of the Indian Army named Major Gaurav. They apparently waited for a counter to that which was furnished by a Wasim Khan, a ‘Kashmiri’ who now is settled in Mumbai and runs a successful media agency (not surprising). So before we go into braindead blaming attempts, let’s analyze the two pieces one by one and check the m…

The Man and the Qu'ran in Bangalore

I stayed for 3 years in Bangalore. There were places I loved in the city, places that I liked and a few places that I hated. There were also places about which I cannot make up any opinion at all.

Among them was the Jumma Masjid on the Dispensary road. This is not to be confused with the more famous Trust by the same name that is close by.

The area around is always busy and the commercial street is also close. The markets were always full of customers, shopkeepers sold exotic items. Just a few hundred meters and you could also visit the markets selling lots of stolen goods, though the shopkeepers often deny that and then wink to show that they were bluffing. It is a fun place for a man to be in, a bit scary for many women, except in a crowd.

Anyway, I always found the place inviting in a peculiar way, the nearby Salafi mosque preaching the evils of other religions, the stench of the urinals, the cheap stolen goods in the market, the prostitutes on the road, the hustle and bustle of t…
