OK... tried it in the new mobo and same issue - card doesn't work in the x16 slot but does in the x4 slot... utterly confused...
Problem solved (I think) - switched the graphics card to the PCI-e x4 slot and it's working fine. Have requested a replacement mobo...
Hi folks, to start with the tech specs.:
Motherboard: Gigabyte GA-Z77-HD3
CPU: Intel i5-3570K
Graphics card: VTX3D Radeon HD 7850 X-Edition 1 GB
HDD: Samsung HD154UI 1.5 TB SATA
DVD/RW drive: Samsung DVD Writer SATA x24
PSU: OCZ CoreXstream 500W
I wrote on here a couple of weeks ago stating that I was having issues getting my graphics card to work in the x16 slot. That issue was sorted, but now I'm having issues in that I can't see anything on screen when I boot up. I can hear everything that I heard before in terms of start up sounds (i.e. the POST beep, the hard drive spinning, the CPU fan starts etc.) but I am seeing nothing on screen. The strangest thing about this is, on rare occasions, I have managed to get a display and then everything runs perfectly normally.
Does anyone have any suggestions as to the problem? I thought it may be my DVI cable, but I have the same issues when trying to run it through an HDMI.
Everything in the rig is only a few weeks old. Any help/suggestions would be much appreciated.
Don't know what did it (I disabled the integrated graphics in the BIOS and changed one of the display settings) but it's now working, so thanks very much, Dorkstar!
Thanks for the suggestions, I'll give them a go and let you know if it works!
Thanks for your reply... The mobo is brand new out of the box yesterday though! How often do mobos not work out of the box? (That is a genuine question, not being sarcastic!)
Basically, as the title of the post shows, the graphics card is not being recognised in the PCI-e x16 slot on the MoBo. It appears and seems to work perfectly ok (not tried any gaming yet) when it is in the x4 PCI-e slot, however. I have asked a friend who is baffled as much as I am.
Could it be a lack of power issue? Should it being in a different slot affect how much power it draws?
I look forward to your help and responses.
Turns out it's (seemingly) a dodgy connection on the video card. It looks to be running ok now, thankfully he has another port on the back of the video card.
After a major messing around session getting a PC fixed, we appear to have a problem now with a flickering monitor. We have downloaded the latest drivers for both the monitor (named above) and the graphics card (Radeon X1950) but still have the same problem. Tried Googling solutions but nothing appears to help. We are using a DVI cable.
Despite trying all of the solutions listed here, nothing worked, so a new mobo has been purchased which I am pleased (and relieved) to say is now working (mostly, still having a problem with major monitor flickering!)
Anyway, thanks all for your help, it was much appreciated.
