HP 530 with Windows 7 (sudden power-downs)
Hello, I am using my girlfriends HP 530 laptop to write this. Basically, the problem is that since installing Windows 7 from Windows Vista, the laptop has been cutting out without any warning. It isn't going into standby or any other power mode, as it starts from bootup when pressing the power button afterwards. This occurs even when the battery is almost fully charged and plugged into the mains.
I have tried flashing the BIOS to the latest version. Recently, the laptop was displaying these symptoms from overheating, but the laptop was also making a really loud sound. We had to dismantle it and found that a large amount of dust had clogged up the vents, which we immediately removed and then put back together. This was only two months ago, since then we have not been leaving the laptop on soft surfaces such as duvets etc.
I have no idea what this could be, I have changed the power saving settings and updated all the drivers.
Does anyone have any experience of this problem?
