Chosen Solution
I have a Lenovo Thinkstation C30 that has both Ubuntu 17.04 and Windows 7 on it. A few days ago, while using it, the system froze and wouldn’t respond. I did a hard reboot, but when the system attempted to boot, there was no startup beep, no BIOS screen, and the boot counter (inside the system) was stuck at zero. I then began disassembling the PC and testing the parts to try and find out what happened. It seems like all of the components (RAM, hard drive, CD drive, etc.) are all operational, and the system seems to “boot”, but there’s no output at all. System is a used Lenovo ThinkStation C30 1095, with 8GB of RAM, an Intel Xeon E5-2630 processor, with a dual boot instance (Ubuntu 17.04 and Windows 7). I’ve used it for 6 months with only one issue before (RAM became unseated during shipping and led to a situation similar to this, but I was able to fix it just by putting it back in.) Thanks for any help!
I suggest resetting the CMOS. This is done by removing the CMOS battery on the motherboard (the little silver circle) and leaving it out, with the system not plugged into power, for at least 15 to 20 minutes. After that, put the battery back and just have the motherboard, CPU, ram, PSU, and GPU connected. (Only use the GPU if your motherboard doesn’t have onboard graphics). DO NOT plug in any fans but the one for the CPU cooler, the hard drive, and optical drive. Also, dont plug anything in but the monitor, if it boots and you see an image, shut it down and then add a keyboard and mouse. If it still works, then plug in the Hard drive and Optical drive. If nothing I just said helps, let me know and we can further diagnose your PC.
When I moved my c30 motherboard to a new home (case) I had this peoblem too , and was very scarry foe me . Even if i just took out the cables and pci cards only , cpus remained mounted and ram added, when I powered it in new case, it powered and was able to power off too , but no beeps and nothing onnscreen. i tried to reset bios , but no beeps , i removed all ram all cards, no beep , i removed cpus , no beep . What worked was to remove everyrhing can be removed on the motherboard, including battery , and i inserted back just the power cables , and cpu 1 power cable but not cpu 2 power cable.but let on just on case fan attached to see if it spin. At this , stage , without cpus it tried to start but powered off in a second . Then i attached second cpu power cable , having all power cables attached but again nothing else no cpus and nothing and tried again to power it. Then i attached first cpu , without hisn cooler, to see if any sign of life and boom it started to beep. Then i added all back and is working even now . I do not know what cause the issue ,maybe the fact i deposited the board in inproper environment , i do not know , but was very strage
