Onboard graphics went out? Lenovo desktop?
Question: I have lenovo desktop that has an AMD athlon II dual core. Im not getting any picture to the monitor. and its not the monitor because ive tried several. Can i just buy a pcie graphics card and hook up a monitor after installing it? Let me add some details. Ive tried various monitors and cables. I can hear the harddrive and fans whirring, so maybe its not the mobo. As far as the onboard graphics...I dont know if its a mobo chipset or built into the processor. Or if that even is how it works? Just black screens, no bios menu options...no lenovo boot screen. If i bought a pcie graphics card...how would I even be able to see to install the drivers for it?

Maybe. It depends on whether just the video section went out, or the motherboard has failed. I don't have enough information to determine if this is a power supply failure or a graphics card failure. Either would cause the "no display" issue. FYI: In an AMD based system, integrated graphics are located in a chipset on the motherboard. The only other option is a dedicated video card. Intel adds a wrinkle with some of their Core i3/i5 processors where the graphics is actually part of the processor itself. Is the machine making any beeping noises when you start it? Some PCs have "beep codes" that announce a hardware failure. You've eliminated possible failures in the cable and monitor, which is good. That leaves possible problem ares as: motherboard, cpu, RAM or power supply. These are the only elements actually needed for getting the initial splash screen up. Hard drives and CD/DVDs are not a factor at the start, you would still see something on the monitor even if they were missing. The good news here is that your data on the hard drive is still accessible. The big problem is that anything that takes out the video circuitry on the motherboard is likely to have damaged other portions of the motherboard as well. If you're technically adept and have the right tools, you could use a multimeter to check the various power supply voltages, check the motherboard for blown, bulging or leaking capacitors, and try various reboots with single RAM modules to try and identify or eliminate the power supply and RAM as possible culprits. Sometimes only part of the power supply fails, so fans can run, but the rest of the machine is dead. Otherwise, it's time to call in the experts, or at least a PC building friend with spare parts. You could try adding a video card to the system, but I'd give you only about a 25% chance that you'll see anything on that card. Sorry I can't be more encouraging.
normally the PCI card disables the onboard when it's installed. To use the onboard remove the PCI and uninstall the drivers/software for it.
verify all connections from the computer to the exhibit screen. Then turn the exhibit off instead than leaving it on standby. change your laptop on and then turn your demonstrate on.
Most motherboards will allow disabling the onboard video, by getting into the bios and choosing the one you want. My board is "auto", so if I put a video card on, it automatically disables the onboard video....others require that you choose which one you want. Check your manual, or if no manual, just get into the bios (F2 on startup at logo, or Del on some computers)..once in bios, look for maybe advance setup or something, and try to find where to set up the video card. If you have no manual, you might (not always) be able to download a copy, by inputing your mobo model. Asus is pretty good about this. Download a pdf file of your manual, then look for how to disable the video.
