Okay I originally bought a Lenovo ThinkCentre computer, and now I have upgraded it so much that from the parts I am not currently using any more I could build a new one. I have put together all of the original parts for the lenovo computer but it won't start. What happens it I hit the start button the fans start up the hard drive starts turning, some times you can hear the driver head start moving as well.
Parts in use:
Mother board- Lenovo, no other details
Memory- Samsung 4GBx2
HDD - an acer one (had to buy it, original is in use)
Power Supply - Huntkey 250w
Graphics card - None currently because I am just trying to get into BIOS, still has same problem when I install my AMD r7 250 of which has worked in the past.
I have already tried: Removing the clock battery and CMOS jumper then putting them on, Swapping around RAM including different RAM, tried a different PSU (no change).
Also no beep errors.
