Device shuts down instantly upon startup
Hey everyone, one of my friends had a pre-built system and I offered to upgrade the CPU and GPU. His original setup was an i5 4440 with a GTX 730 and 12GB RAM. I replaced it with an i7 4790 and a GTX 750ti. After testing five times, he asked if he wanted more RAM, so we upgraded his 12GB (4x2 + 2x2) to 16GB (4x4). This caused the system to fail to boot. Initially, it would load the Dell logo and the loading bar would start, but then it would randomly shut down. I was handling the cooler during those tests. Later, when I pressed the power button, the fans spun and then turned off. I ran a Dell power test with the switch in the back of the PSU, and everything powered up. The CMOS voltage came out around 3V. I inspected the pins and found none bent. I removed the CMOS and attempted a BIOS reset, but nothing changed. I’m unsure if the motherboard is damaged. I tried different RAM configurations—using the old one worked—but nothing else helped. When no RAM was installed, the same issue persisted. I’ve attached a video documenting the problem. Thanks for the info! VID_20200401_180317.mp4
I understand you wanted to try a different approach. First, cut off all power from the system—either shut down the PSU or unplug it and press the power button several times. If not, the BIOS won’t clear. Then, take out the watch battery you noticed and leave it out for 5 to 10 minutes. After that, put the battery back in and restore power, testing again. If the issue is related to BIOS settings, this should resolve it; otherwise, the system might be detecting something and entering protect mode. If this doesn’t help, reset the old RAM and run a test. It should help identify whether the problem lies with hardware or software. Good luck.
