Put original ram back. Remove CMOS battery unplug everything Hold power button to discharge. Then put power cord back and see if it turns on. Hopefully there is no antistatic damage      
SpeciationsCPU: Intel Core i7-11700Ram : 8GB Model HMAA1GU6CJR6N-XN (one that orginaly came with)512Gb pcie sdd500w PSU This ram i tried to upgrade:CORSAIR - VENGEANCE LPX 32GB (2 x 16GB) 3.2 GHz DDR4 C16 Desktop Memory (Bought from Best Buy)[URL] I was trying to upgrade my desktop with this CORSAIR - VENGEANCE LPX 32GB and tried to add it with my 8gb HMAA1GU6CJR6N-XN.Yes, I set it properly, but when I turned it on, it won't boot (blank screen and it shuts itself off after about 20 seconds). I tried to remove the CORSAIR - VENGEANCE ram and put the 8GB HMAA1GU6CJR6N-XN back the way it was however it still won't boot. Then I found out that I am actually getting the 2 amber 1 white blinks (which is the case of CPU failure).This is very worse than I thought. This very unbelievable. Things I tried:Resetting ram.Unplug system, remove base cover and disconnect the battery. Hold the power button for 30 sec. Nothing Still 2 amber 1 white blinks. I fear I wrecked the CPU I am very shocked and upset here. Did this "CORSAIR - VENGEANCE LPX 32GB" causes the 2 amber 1 white blinks (CPU Failure) on my Dell XPS 8940?Or maybe something else? Any help here?Thanks in advance.
