Hello everybody!!!!
I'm working an HP dv9000 and am having some very weird issues that I can't seem to find the culprit to.
here is what happens
-about 10% of the time the laptop boots perfectly into vista, audio working fine and everything. This usually happens on fresh boots. For example, if the computer is left to sit overnight or a few hours I'll comeback and it'll work fine.
-about 20% of the time the computer boots with "no audio device detected"
-about 70% the computer posts and when it trys to boot into windows I'll either get 1)a blank black screen or 2) a black screen with the MICROSOFT CORPORATION logo at the bottom very dimly. I've let it sit there for about 20 minutes and nothing. So after it does nothing I use the power button to restart the computer because ctrlaltdel does not work. Then it'll ask me whether i want to boot in safe mode and all that good stuff. If i select START WINDOWS NORMALLY it'll successfully boot into windows about 30% of the time and the other times it'll give me one of the black screens described above.
-this is a fresh installation of vista on a new hdd because according to the owner the hp self diagnostics reported a bad hdd. I did a quick tested the HDD with HD TUNE and it passed. HOWEVER, i went ahead with the new hdd because I had seen cases on other acer laptop where the disk would show healthy smart status and pass hd tune but for some reason I couldn't boot into the OS CD unless i took out the hdd or replaced it with another.
- I also had a hard time having the pc allowing me to boot from the dvd drive. The bios recognized the dvd drive but it wouldn't boot from it no matter what i did. So i switched the Vista DVD for a 7 CD and pressed f9 to select boot device and there it was. After this, i simply switched 7 for Vista again and selected the DVD Drive as a boot device and it worked.
What i've tried so far:
1-put the old HDD back in and see what happens. Once the new hdd starts giving the blank screen, if i put the old one in, it'll do the same.
2-i've tried switching the hdd from slot two to slot one(this particular hp machine has two hdd slots. If i put it in slot one the machine simply reboots and never posts.
3-I've ran memtest and RAM passed. I've tried running with one stick, one stick on another slot, and a completely different stick.
4-I've tried doing all the windows updates up to sp2. I've installed all drivers on HP website including the audio but somehow i can't get the audio to ever work consistenly.
5-I've flashed the latest bios, a middle date bios and the original bios and none of them show any improvement.
6-Thinking it was the maybe the DVD drive that for some reason causing an issue, I tried booting without the DVD drive and with a new DVD drive and nothing happened. It made no difference.
I'm baffled by this computer!!! I have no clue what to do with it. I've tried everything I could think of. Please help!
