i bought a crappy motherboard at first, and had to deal with regular crashes..blue-screens... and also made a ghetto solution for an extra fan on top of my case...that fan is just attached by 1 screw jutting out the top of the case...and supported on the other side by the corsair h80i radiator... hahaa
and when i had my 1st pc (in the athlon 32 days), i used to press the on button...it never used to start...so i had to slap the cabinet...and then press the on button...and it started automatically... no wonder it end up dying
