I have had my HP Pavilion g6 Notebook PC (with Windows 7 Home Premium 64-bit Service Pack 1) for less than a year and I am encountering a ton of problems. Whenever I go to open a program, it unresponds for a short while before I can continue to use it.Sometimes my keyboard acts up, for e.g. if I were to press T whilst in an internet browser, it would open a new tab, as if I was pressing the CTRL button when I'm not.Sometimes my laptop shuts down - sometimes there is a blue screen error message before, other times it just shuts down without one. I have Trend Micro Tiatanium anti-virus protection and have done scans and nothing has showed up. Does anyone have any ideas as to what is causing this and what I can do to fix it?
