Pavilion Elite m9452p: Flying Blind with a HP Pavilion Elite m9452p - no video at all - HELP!

It is a Core 2 Quad Q8200 processor Intel PC with 8 GB of RAM and 750 GB drive HARD + 1 TB back up drive running Windows 7 Ultimate 64 bit (it came with Vista 64-bit home edition Premium, but updated for win 7 just now).

It has always worked perfectly, but last week there was no video at all when I turned it on. The monitor says 'No Signal' on an otherwise black screen when turned on.

HDD lights indicate activity and I can hear readers spinning and the LEDs for the DVD and the wireless signal light up as well.  In addition, ports Ethernet led Flash and show activity, as does the DVD player if I put a disc, but no video at all.

I did the following to try to resolve this problem:

1. I checked the monitor I was using is working;

2. I always connected this PC to another monitor DVI to work with no luck.

3. I have connected the PC to a working VGA monitor with no luck.

4. I connect the VGA monitor to the VGA port, integrated with no luck.

5.i tried to boot in the BIOS, but there again, no video is not sure if it goes to BIOS or not;

6. I have read somewhere that the built-in VGA port will not work if a video card is present, so I removed the video card of exisitng and connected to the VGA integrated with no luck;

7. I bought a replacement video card (it came with a MSI V240 500 MB PCIex16 card and got a card XFX Radeon HD 5450 1 GB PCI ex16); I installed the new card and tried again without success;

8. I don't remember if this PC was set to beep on the POST before he always started quickly and without problems. Now that I'm looking for any beeps, I don't hear everything but yet once, can't remember if it still beep before;

9. looks like it's a hardware problem, but I also tried to boot from a drive of W7 64 Bit repair, but even once, no video so don't know if it works.

The last thing I remember having seen it was a Windows Update I think to include an optional update to the video driver. I don't remember if I acdcpeted that one or not, but it seems to me that the drivers for the MSI card (nVidia, GE Force pilots I think) that does not correspond with an AMD Radeon graphics card drivers - this is why I opted to get the Radeon card).

I have not tested the original map, mainly because I don't have any PC with which test (I have a Core 2 Duo Pc with a PCI slot ex but not an ex16 PCI card. I don't know if this card would be retro-compatible with this PC or not).

I vaguely recall disabling the onboard VGA in the BIOS, but do not remember if it is with this PC or another.

I hope someone has a way to put video on so I can uninstall all recent drivers or updates that may have caused this (or I can enable VGA integrated in the BIOS).

I sure hope the MoBo is not messed up (it does not fuel upward hard drives, the DVD player and the fans, etc.) but with no video, it is difficult to know what is happening.

Help!

OK - SOLVED!

After re-reading my post, I realized that if the BIOS for the integrated video card setting had actually been changed, I could re - put these default settings by resetting the CMOS.

I had not tried to clear the CMOS by the cavaliers to the MoBo, so I'm the manual MoBo and I cleared the CMOs (which would reset the BIOS to factory settings). I restarted the PC and voila! I now have the video!

Sometimes the simplest things will solve the whole problem!

I felt bad that I couldn't solve this problem, as I can usually solve everything that came out on any of my systems, but here I answer my questin oiwn and solved the problem - I hope this will help others too!
