Device starts up yet fails to connect to the screen.
Scored a free Alienware R10 today with pretty good specs: - 128 gb RAM - Ryzen 5950 (it's a 16 core 2020 vintage) - RTX 3060 Ti And of course, the caveat of not guaranteed to work but still too good to turn down and worth putting a little money into getting it running. So here's what I'm facing: The computer will power on - leds light up, jet engine of an AIO coller at full blast before settling down, GPU fans running with side LED lights going. So clearly it's booting up and something is happening. But no video output. I've tried: Trying a spare graphics card I had laying around. It was working last time had it installed and it's been in an antistatic bag since. Changing RAM. Same as above it worked last time I used it Checking wire connections What else to try? Could my CPU or motherboard be the culprit? I do have another computer with an AM4 Ryzen so I'm almost tempted to try swapping. Hoping I can drum up some other things to check before going that far.
Have you personally observed the PC function? Is the battery still active? Can you replace or verify the voltage? Inspect the CPU and socket condition. The bent pins are saturated with thermal paste... PSU is fine? Would you like to examine the other components separately? GPU isn't working properly.
It was an IT promotion at work. Seems to be in nearly new shape. The battery compartment is just a typical watch cell, right? I have a few fresh ones to swap in. The GPU slot appears fine – it has two and I’ve tested each one. The power supply unit is a bit uncertain; maybe it’s the issue even though the PC starts up? It’s rated for 1,000 watts, but if it’s faulty it’s obvious. I have a functional PSU from an older AM4 build, so I’m okay trying it out. The Alienware motherboard spec isn’t clear (it looks like mATX), but the power connectors seem standard. The other PSU is likely lower, around 650 watts.
128GB RAM! How many modules? Can I shrink it to 32GB? Are you connecting via HDMI? Have you tested another monitor, TV, or cable? Edited March 11, 2025 by leclod
100% board showing how terrible those OEM boards are, I wouldn’t spend too much time trying to fix it and just grab a used B550 and call it a win, unless the RAM is also faulty it should boot up fine.
These boards are uncommon. ATX MATX etc., so the case might need modification, etc. Be careful and save yourself some headaches.
Perfect setup ready to proceed. Disassemble carefully and remove all components. Replace heat sinks and CMOS battery. Short-circuit the CMOS temporarily, then fully discharge the system. Clean thoroughly with water and rinse for several hours or use a dishwasher without detergent. Allow drying overnight. If the device shows signs of life, it should function again; otherwise, discard it.
Couldn't confirm everything. All the cooling units remain connected and nothing seems altered. If I reach a stage where I swap in a CPU, I'll examine this thoroughly. This setup has four 32 GB sticks and four 16 GB sticks; I also tested swapping RAM, but it appears I need two slots open. I accessed one slot and the AIO cooler kept running at full speed instead of adjusting after boot-up with multiple sticks. I have another computer based on DD4 that I plan to use for testing RAM. I’m using only HDMI so next I’ll check Display Port. The HDMI cable functions (my PS5 was connected), ruling out the cable or monitor issue. I also replaced an 760GTX card that previously worked but still didn’t. This is my main hypothesis based on my attempts. I’ll swap components around with an extra AM4 board I have at home. So, is this a standard mATX board or am I misunderstanding? I’d assume it’s an mATX if possible, but that would be great if I could use any standard board. A quick online search found a new B550 board around $90, so I’m confident in purchasing a replacement to get this system running. I appreciate the LED effects and hope there’s a way to preserve them. EDIT: After some research, it seems a non-OEM motherboard could work with minor tweaks. It looks like a typical mATX design, but modifying the power button and removing the rear IO panel might help. It doesn’t appear overly difficult.**
Signs suggest the motherboard might be faulty. GPU and RAM are functioning on another machine, which was the main issue I needed. I switched PSUs on an Alienware and saw improvement. I haven’t swapped the CPU yet—still weighing options since this system seems to have the original CPU. Instead of just fixing the board, I’m thinking about replacing the case. I appreciate the Alienware design and how it integrates with enterprise hardware, making upgrades easy. Spending about $80 on a case makes sense compared to the time saved by avoiding custom modifications. These boards are expensive, around $200 on eBay, matching a non-OEM motherboard and case. I’m considering this as a file server and need a compact case with decent storage—4 SSDs plus 2 NVMe drives. Unless someone else has tips, I’m open to suggestions.
