This is my first post on this forum so I hope I will describe my problem well.

I bought a Sony Vaio E Series from Sony's Online store here in UK in August 2010.

The model number is: VPCEB2X5E

It's specifications are:

• Intel® CoreTM i5-520M, 2.40GHz
• Windows® 7 Home Premium 64 bit
• 500 GB Serial ATA (5400 rpm)
• 3 GB 1066MHz DDR3-SDRAM
• ATI MobilityRadeon HD5650 1GB

Recently I have faced the following problem:

During gameplay my notebook has frozen for about 1-2 minutes and then turned off by itself and rebooted. After that incident until lately the notebook took ages (approx. 20 minutes) to boot and 10 minutes to shut down. After it was successfully booted Windows was running exceptionally. Like there was no problem.

This problem was bothering me very much and I decided to reformat the system to investigate if was Windows system failure or hardware failure.

I have to note that my profession is a Computer Scientist and I understand at least the basics of computer hardware and software failures. My mind was saying that this is definitely hardware problem but I wanted to eliminate the possibility of a software problem first.

So after I reformatted the system was working pretty well, for only 4 days. Then the same freeze happened and this time it won't even boot neither in Windows, in Safe Mode or in recovery partition. Every time it went showing Windows logo and then showing the windows background it got stuck.

At this point I realize is either a hard drive or RAM failure.

I ran couple of hard drive diagnostics and most of them reported no errors. Even the SMART reading passed all the checks.

Can anyone help me understand what the problem with this notebook is so I can fix it?

I don't know if my notebook has 1 year of warranty or 2, if can anyone knows how many years warranty vaio notebook have by default please let me know.

Thank you in Advance for your help.
