I have an HP Pavillion m9500f PC (running Windows 7 64-bit Home Premium, upgraded from Vista). The machine has a NVIDIA GeForce 9500GS video graphics card. NVIDIA is replacing those cards becuase of excessive fan noise. To get the repacement card, I needed to open the box and remove the card to see serial numbers, etc. I replaced the card -- feel certian that has been done right, card is sitting securely and appears connected. After reconnecting peripherals and reattaching power, the PC powers up, but nothing else happens. The hard drive light on the front of the box is not lighting up and nothing is showing up on the monitor -- just a black screen (light on monitor is orange, not green which I think means it is getting no signal from the computer, but am not sure).

I thought perhaps this was video issue becuase the card was loose, so checked again and the card is settled securely in the slot. I am at a loss how to start troubleshgooting this issue. Any ideas anyone may have would be very much appreciated! Am VERY worried!!

Hi Plug 'n Play :)
You will need to open the computer case again & check a couple of things out,
Before touching anything inside the case make sure the power cord is removed
& that you take anti static precautions, do this by touching a bare metal part
of the case;
Remove the gfx card, make sure the slot is free of dust & then reseat securely,
Do the same with the memory sticks,
Make sure all connections are plugged in securely, when you reassemble check that
there are no bent pins on your monitor lead & that both ends are securely connected
make sure that when you switch on the monitor is not switched to stand-by, power up
your computer, just in case this doesn`t work it may be necessary to clear the BIOS,
so can you post any motherboard details that you can see printed on the board, you
may find these by the CPU & between the pci slots, hopefully this will not be required
but we can look for a MB user manual while you go through the above list of checks.

Hi phillpower2,

Can't thank you enough for the quick response, but it appears I've managed to resolve the problem. I had already reseated the gfx card, so I think that was ok. Surfing for other possible solutions I found some references on the Microsoft site to problems others had with Win7 on reboot. Suggestion there was to boot from the upgrade install disk. I tried that and was able to reboot from the DVD. On reboot, I was offered a number of System Repair Tools, including a memory check, which I ran. It found no problems, but the hard disk became responsive again after the auto-restart. I removed the DVD and the computer now rebooted from the hard disk. I don't know what caused the issue, but it appears not to have been hardware-related. In any case, it all seems fine now.

Either way, I am impressed by your and others' willingness to be so helpful on this site. You've made me a Geeks-to-Go fan!

Thanks again!
