Re: no boot, 1 long and 2 short beeps
Hey mate,
you said you took extra video card, so you have on-board one...
Take out your extra video card and let on-board graphic card be your primary video...
So, when you try to boot up without graphic card, you can not go further then ThinkCentre logo... Open the case and remove CMOS battery...
Leave this way for about 1 minute, hit power button couple of times [make sure you have power cord of from PSU]...
Put back battery and start PC...
If it does not pass through logo, then I could suggest you to unhook everything from Motherboard and leave just processor and RAM memory [you said you have on-board graphic card so better take out extra graphic]...
try to start PC...
report back please...
