Hi my 5 year old Dell XPS8920 tower crashed a couple of minutes after start-up today. When I tried to turn it on again, the power button flashed 2 amber lights repeatedly. According to: https://www.dell.com/support/kbdoc/en-au/000145872/a-reference-guide-to-the-xps-desktop-diagnostic-i... this is a "Motherboard: Power Supply" issue.

I tried isolating all of the components that connect to the PSU. I found that when I disconnect the CPU from the power supply and I try the BIST test (https://www.dell.com/support/kbdoc/en-au/000125179/how-to-run-a-power-supply-unit-self-test-on-a-dell-desktop-or-all-in-one-computer), the power supply light turns on and I can hear the PSU working. The power supply light turns on with the other components connected to it (GPU, disk drive, motherboard etc) provided that the CPU is disconnected.

Is the issue my CPU?

Any assistance would be appreciated.

I purchased an XPS laptop at the end of 2017. Just the other day, it wouldn't turn on, and the LED indicator was blinking 2 amber, 1 white, which apparently indicates a CPU failure. This is pretty frustrating because it hasn't been 3 years yet, and it's been used only very very lightly. I've tried performing a system reset and power cycling, but no luck.

Although it's out of warranty, I noticed that I could renew it for about $100, and thought that perhaps it would cover the diagnosis and repair costs (wishful thinking, I know). In the link above, someone noted that the repair (replacing the motherboard) would cost $300+, which is more than I'd like to spend. But $100 including a year of warranty? That would be reasonable.

Just to make sure though, I jumped on the Dell support chat, where the representative kept telling me that I would need to have it diagnosed first for $59, get the laptop repaired, and then I could renew the warranty. This didn't make sense to me, since I could literally press "checkout" on the warranty renewal right now. He asked me how much I thought the repair would cost, and I said "at least $300 to $400," to which he replied "it would cost $278 plus tax" (how did he know it would cost that much?). So anyways I told him that that was more than I would like to spend, and he said "I understand. Thank you for choosing Dell."

I'm not sure what I want to do right now but it's just annoying to have a high-end (ish) device die like this after not even 3 years of light use. I really like the XPS, but man, I'm not happy with Dell at the moment. If anyone has any advice (is it hard/expensive to replace the motherboard?) or anything to share, that would be great.

i have two dell optiplex 5050 slims and I tried putting a second stick of ram in one but I get the error code 2 orange flashed then 7 orange flashes what should I do?
