Are you using an Intel onboard (IGP) or dGPU (GPGPU) machine? The majority of high spec systems come with the Radeon 7570, which is a low profile GPU converted to work with a different bracket. There are other cards that don’t do this, but they were all optional CTO upgrades. The difference between the consumer 7570 vs. business 7570 is the secondary port; the consumer card in the XPS is HDMI/DVI and the business card is full size DP/HDMI. Same junk card, different ports. For onboard, it’s usually bad RAM.
The low end GPU Dell shipped with these often die due to the small cooler and GPU heat output being bad enough under load it cannot quickly dissipate the heat - it’s not uncommon to get these low profile conversion machines with evidence it WAS once a machine with a GPU from the factory - that’s how you know the GPU died. The problem is these low profile GPUs are notorious for failing due to insufficient cooling without warning unless it has a joke dye like the GT420 (which shouldn’t exist). It’s made worse by the fact there is often no warning - it’s good one day and dead the next. Personally if I got something like this again and it had one of these GPUs I wouldn’t throw it out if it worked, but I’d probably throw it out and blank it off if it had a fatal issue so I can shop around and get a GPU I like since the mainstream CPUs ALL have onboard graphics.
If you’re lucky it’s just a bad driver and booting on the Intel onboard without the GPU installed (Dell has a POST block with a GPU installed) so it can be removed and reinstalled with the AMD or WHQL (Windows) driver. We don’t know what card you have explicitly, so you will need to find out and locate the correct driver. Just don’t be surprised if it fails again permanently.
If you don’t want to chance it, these are your choices:
- Buy a modern midrange GPU and replace it (requires driver change)
- Remove the card and switch to onboard video (requires driver change)
If it didn’t ship with a GPU, the RAM is bad. Get a set of DDR3L 1600MHz - at least 16GB of it especially if you plan to keep the computer in the long run. If not, remove the bad module as long as it’s reasonable - think 4-8GB of RAM after finding the dead module.
