I'm hoping I'm posting in the right place. I am new to this forum.
A few days ago I turned on my HP Pavillion dv6449us laptop, and all the lights on the keyboard, and the power light came on, but I had a black screen (the monitor never came on).
I played around with a little bit and found that if I hit F8 when I pressed the power button it would let me start up in safe mode (sometimes). I talked to HP (which weren't much help because my warranty ran out 2 months ago on a 14 month old computer!!!!) He did help me get into my Bios (which I could have done myself)
I eventually got the computer to boot up without hitting the F8 button but my screen was messed up. You could see Windows Vista starting up but there were about a million lines crossing the screen (which led me to believe there was something wrong with my video card). I started back up in F8 mode and uninstalled my NVidia graphics card and restarted so it installed the standard VGA driver. (I found this as a solution online).
I started up the computer and again got the black screen but the LED's lit up. I noticed that my hard drive only blinked twice before nothing else happened. After a few seconds the computer rebooted itself. This was continual. I just let it continue to reboot (wanting to see if anything would happen) and it eventually started up on it's own.
If I restart the computer (after I got in ok once) I was back to the black screen.
I have reseated the memory, hard drive and video card and put them back in. I took out the battery and unplugged the cable and drained the internal power. I plugged it back in, with no luck. I have reformatted, leaving me to believe this is not a software problem.
I'm out of options, but I really don't want to pay a lot to get it fixed, but I also don't want to buy another computer, I just bought it 14 months ago.
A little info about the computer:
HP Pavillion dv6449us (AMD Turion 64x2)
Windows Vista Home Premium
2 GB Ram
Thanks in advance for the help. I hope someone can help me fix this...
