Its happening from the time I have bought this laptop. This intel centrino 2.53 Ghz based Vaio VGN-CS36MJ is really messing around with me a lot. every time I starts this machine, during start up everything runs fine for about few minutes but then later on everything seems to be failing down. Starts from screen going black then the hard disk light go off. Slowly the speakers too goes off, the USB ports shut down and if I connect any external display then it might show no signal message during this stage of time. The power light and the battery charging (if connected) stays on, also the fan stays normal and runs as properly as it run during the normal time and it never recovers from this state until I restarts the complete system all over again forcefully. But then even after restarting the machine everything starts again from then onwards. I have been making several attempts where I used the recovery disks for making it factory fresh during this long process.
The strange thing is that the laptop never dies during this stage of time. However the story repeats after the windows is started. For you information let me tell you that I also ran a Vaio Care hardware diagnostic and you know it showed me that the hardware was working well and fine. At the end after all attempts being failed I took my laptop to the Service Center, there I was told by them that the GPU of my system has failed and therefore the motherboard needs to be replaced. They charged me heavily without even replacing the board, said that they might charge separately for the replacement. The price of the motherboard was almost equals the brand new Sandy bridge laptop. I didn’t drop the laptop anywhere until yet then how come the motherboard and the GPU got corrupted. My Laptop is just 1 year old and it’s still less than 3 year warranty but I think the warranty is of no use. Neither of the sony online support nor the service center is helping me with this issue. Trust me its since 5 month I have not yet used this laptop, it has for now became completely useless for me. Please help me out, what should I do. Is there anyone who has the best suggestion that could help me out?
