OK a family member has had a HP pavilion desktop computer since Christmas I wasn't the one who purchased it. I'd like to list all the specs but honestly I don't know what they are and neither does the owner and I have never been able to get enough time on it to find out in device manager.
What I do know is its an 8 core i7 with a nvidia graphics card, 8GB of RAM and windows 8.1 all listed on the box but no more specifics.
This computer has a blank screen with no video output, it just went blank when in use. It usually flashes the HP logo before windows startup when powered on but now it doesn't implying that there is no BIOS/EFI firmware communication with the video card either so I don't think this is a windows 8.1 issue such as a driver. Further supporting that is the fact that I can put the computer into sleep mode by pushing the power button once as is configured in power options and the fact that I can discover the computer identified by its name once the network from other machines.
We normally use a DVI-I to VGA converter to the screen as it is an older screen so at first I thought the screen might be broken as there is no signal, however I have tried the DVI to a HDTV, the HDMI out to the same TV, and the DVI-I to the TV'S analog VGA input and still no signal so I am sure this is a video card issue.
There is a noise coming from the PC which sounds like a fan running at full speed which I am assuming is the GPU fan it is strange though because it sounds like the noise is at the front where the hard drive is and there is also a grinding noise sometimes but I am sure windows is loading perfectly which rules out the hard drive.
I have studied computing and am fairly proficient in fixing computers so I am fairly sure this is a video card issue and I could swap the PCIe card out but we don't want to spend money in a new card so we are looking for a refund of a repair under Warrenty so that rules out opening the case. The problem with the refund is that we have data on there which was never backed up by the owner and we will lose it even though the HDD is fine.
Any way to get the data off without opening the case? Any way to get a video output without the graphics card like with some sort of USB3 to HDMI adapter?
Help is appreciated.
EDIT:Just realized I posted this in the wrong thread by mistake sorry. Could a moderator please move this to the correct section?
