I have a Sony Viao 2005, model VGC-RB38. Recently, I have been experiencing a series of freezes in which I could not hold the power button down to turn it off. Over the past 2 weeks I've been experiencing freezes but no explanation for them. My computer is in great condition 88% space, 3 years old and clean of any viruses. In each those cases, I have been forced to plug it out my computer because it would not respond to any CTRL+ALT+DEL or holding the power button down. Before, the computer was able to start back up again, but I received NO prompt or warning that my computer has been incorrectly shut down which is strange. I immediately ran some checks on the system, checking the device manager to see if all hardware was working properly and they were. Then I checked to see if my harddrive was damaged. Last night, after holding it down for well over 5 minutes I was forced to pull the power plug on it. However, after doing so my computer has refused to start up. I can hear the fan spinning, the lights blink at the front and it makes a sound that signals that it has been turned on but less than 3 seconds later and powers back down again. I don't smell anything strange that may hint at anything being fried. Is there anything I can do?
