Screen Card Doesn't Work Properly In Certain Mods
Screen Card Doesn't Work Properly In Certain Mods
I’m sharing my first update here. Over the past two decades, I’ve assembled my own PCs and recently upgraded my AM4 system. I’m now downsizing or combining parts into functional machines. My setup includes a Zotac GeForce GTX 1070 Ti and an EVGA GTX 470. I also have two motherboards: a Zotac H55-ITX with an i7-870 processor and an ASRock A320M-HDV with a Ryzen 7 1800X. My plan is to pair the H55-ITX with the GTX 470 (i7 build) and the A320M with the 1070 Ti (1800x build). The 1800x version performs excellently. The i7 model I’m using dates back to around 2011 and has had a few issues.
My troubles began after replacing my old HP case from 1998. The i7 was installed inside it, so I removed the case and discarded the hardware. When I reassembled everything—testing on different machines—I found that the GTX 470 wouldn’t display anything on the monitor at all. However, when connected via mini HDMI while another monitor showed a status, the screen went black. It seems the monitor recognizes the connection but can’t output an image. I’ve tested this with three other systems (a CHUWI larkbox, the 1800x build, and my 5700x3D PC) without issues.
After swapping the GTX 470 for the 1070 Ti, it worked perfectly. I tried updating the BIOS on the H55-ITX but got no improvement. Regressing to the oldest BIOS also didn’t help. I installed an E6750 Core 2 Duo and attempted to access the HDMI port, but that failed too. I’ve checked all cable connections and adapters; they’re working fine when plugged into different cards. I cleaned the contacts on the 470, thought about dirt in the PCI slot, and even tried using different cables, but nothing changed.
I’ve booted from both Windows 10 and Windows 7 drives without success. I don’t want to permanently replace the video cards, as that would make the 1800x build largely useless. I’m a bit stuck and hoping someone can spot what’s preventing the GTX 470 from functioning properly in this configuration. Thanks for any advice!
