I tried the F10. The monitor just said no signal again and went to sleep. I also tried putting the old HDD on and got the same results.
Since I can't get anything on the screen to give you real specifics, I can only give you the information on the side sticker and some info I had written down before:
HP Pavilion p6310f
AMD Athlon II X4 630 Quad-Core Processor
6GB DDR3 system memory
1 Terabyte hard drive
SuperMulti DVD Burner with LightScribe
Windows 7 Home Premium 64 bit
Came with NVIDIA 9100 integrated graphics, put in a better NVIDIA card but I can get the name of it out of the system
From before I lost the monitor use:
HDD name?: WDC WDEADS-65M2BO SCSI
SATA, SATA2 interface
Transfer rate: 300 Mps
6GB installed memory
This is the information for the new HDD I purchased:
WD Caviar Blue, only 500GB because I never used the full 1T
So I still got no signal with either HDD hooked up, even with the W8 disk in the drive for start up. Neither VGA or DVI work. Then I did a real good job of blowing out dust with compressed air, reseating connections, including the video card. To my amazement, connected to the old drive, the screen came up but the dimensions were changed. I was able to download malwarebytes and it took just over 4 hours to do a complete full scan. It found 20 objects, I removed them all, clicked on restart, then after shutting down I was back to the no signal stage. I tried turning it off completely, rechecking the connections, let it sit about 20 seconds, then restarted. Still no signal. I do notice one particular thing - and it does not make me feel good about the future of my computer - when I start it up just the fans seem to go on. I'm not hearing that audible whirring familiar to computers starting up and the printer does not make any of the noises it does when it reboots with the computer reboot. Near as I can tell, the computer is not getting to the point where it checks the peripherals. As I have heard this asked on other places I have been looking at, there are no beeps upon starting the computer.
I'm getting that creeping feeling that my mobo is fried.
