Hello so I have a dell optiplex 7050 and few days one of the monitors wasn’t showing display so I powered it on and few seconds later the pc crashed and then when I tried to power it on at first it showed 2,7 which is ram error I put in new ram and now it shows 2,5 which according to the manual means bios checksum failure and I don’t get any display and usb ports don’t work. I tried dell forums they kept asking me to drain power replace cmos battery I tried it all still the same please help me!

My Dell Optiplex 3050 is blinking twice in an amber pattern, lasting a few seconds before blinking once more.

Do I need a professional to look at this or is there any way I can solve this?

I have recently added a 500W power supply to my 3050 SFF Dell PC; due to upgrading graphics card. I have plugged in all the cables into the motherboard and GPU, however when I start it up the light is blinking amber colour twice (inbetween pauses). Just wondered what the problem is, as well as how to fix it.

EDIT: Good news! Turns out, it actually was the motherboard that seemed to have died. Moved all of the components over to a new board and it works like a charm now! Thanks for the assistance in narrowing this problem down, everyone!

Hoping to get some help with this.

Dell Optiplex 3080 Micro powers on with no display and with a solid white power LED after a month and a half of usage as a headless server. Ethernet cable is plugged into the back but shows no lights indicating network activity and checking my router, it says the device is not connected.

Tried several HDMI and DisplayPort cables into various different monitors with no success.

In addition, I tried holding down the power button for 20+ seconds. After that, the power LED blinked white 3 times and then stayed a solid white after that. Did not see any amber lights. No connection or network activity lights via Ethernet according to my router as well. Display connection via HDMI and DisplayPort is also nothing as well.

Looking at the manual on Dell's website regarding diagnostic LED behavior at https://www.dell.com/support/manuals/en-us/optiplex-3080-micro/optiplex3080_micro_sm/diagnostic-led-behavior?guid=guid-07853ede-4844-43b1-8f55-6d1a070dd898&lang=en-us, it says that 3 white blinks is a RAM problem but that the amber blinks has to be 2 as well. Would this be a RAM problem as the power LED never showed any amber lights at any point during my attempts to fix this.
