I recently bought a new graphics card to update an old desktop (Dell Optiplex GX270 Mini Tower) with the hope of a mediocre home theater PC. After much research, I bought a HIS ATI HD4350 512MB DDR3 graphics card. However, I'm having trouble getting it to display video.
The power supply is just the factory Dell 250W max unit (14A on +12V). The graphics card company recommends a 300W supply, but everywhere I have read has said that my power supply should EASILY handle this graphics card. I have read about several people using much less (watts and amps) and having no problems. I wish I had an extra power supply to test the computer with, but I don't have one. So this is the next step unless there is something I'm missing (hopefully).
So basically what is happening is that the computer has no problems if I use the integrated graphics and associated VGA output. However, once I put the AGP card into the slot, the monitor acts like it is not getting a signal from either the graphics card or the factor VGA port. The rest of the computer is getting plenty of power and I'm pretty sure that it is fully booting into windows, but the monitor is blank. As far as the card, the fan is spinning and it seems to be getting power but there is just not video output. I've tried the VGA, DVI, and HDMI inputs. I've adjusted the AGP aperture in bios and nothing changed. I've also tried disconnecting everything but the PSU, fan, hard drive, and video card, but this made no difference. I have tried uninstalling the integrated graphics driver, as well as having the most recent one installed. I don't have another computer with an AGP slot to try the card in. I'm at a loss for what could be going on, since it seems to be getting power.
Here is my info from CPU-Z:
CPU: Intel P4 (Northwood), Socket 478 mPGA, 2.60Ghz, 200MHz bus speed, 800MHz rated FSB, L1 Cache 8 KB, L2 512 KB
Motherboard: Dell 0H1290, Intel i865 chipset, Bios Dell A07 (updated to this and it didn't help)
Memory: 2GB DDR Dual Channel
Graphics: Intel 82865G Integrated Graphics Controller
OS: Windows XP SP3
DirectX 9.0C
Any ideas? If I can't get it working soon, I need to ship it back to Newegg to meet the return policy, so I'd appreciate some quick help. Thanks!
