Ok so I've started my pc after some months since I just got a graphics card but it seems that my pc won't load past the windows logo screen doesn't matter what I do I've checked bios, reseated the ram and cmos battery, tried different hard drives with windows 10 (my primary win) and even windows 7 and xp nothing seems to work, when installing new windows to drive after the installing windows (5 part thing) is done and it asks for restart windows boots up to win logo screen then it says your pc ran into a problem, error 000021a ...it was fine the last time I used it never had any issues as such..my specs are xeon x3440, 4gb ddr3 1333mhz ram, r5 240 1gb ddr3 (it is to notice that this is the only new component I've added)
