Hi. I have a hp G62-225NR Notebook running windows 7. I was browsing the internet as usual when the computer suddenly shut off and restarted itself, then not too long after it restarted itself it shut off again accept this time it only came to a blank screen with the blinking curser at the top. I've tried troubleshooting online and I went to the BIO and restored default setup and did the hard drive and memory test which both passed. I can't get to safe mode, or don't know properly how, and when I hit f11 for system recovery it just goes back to the blank screen with the blinking curser. The computer was working just fine, it seems like there must be a fix for this.
