Please help...Computer freezes!!

Ok well i have a systemax... When i turn the computer on sometimes it loads and before it even gets to windows, the monitor just liek goes into sleep mode. I dont think its a setting, and if it is, i cant change it because the computer freezes or the monitor just goes...ANY HELP!!!

Thanx in advance

 

We'll need some more info, like what operating system etc.

If it goes into 'safemode' (?) it's likely a conflicting driver, as safemode doesn't load any drivers.

It's worth doing a thoro' scandisc in safemode with auto fix unchecked, and this will tell you where there may be probs.

If this doesn't work you'll have to go the slow route and disable hardware one by one until you find the culprit. or see under Device manager if there's any yellow ?'s which means a driver is corrupted.
