Windows won't start

[demon8991]

Just restarted my computer and now it wont load up, it gets to the welcome to windows screen and just gives me a black screen and completly locks up! It wont boot into windows safe mode either?

Cant beleive it really my computer has been solid as a rock for nearly 4 years never had a single problem with it!

Any suggestions! (reinstall being the last resort)

What have you changed ? What have you downloaded lately ? What have you installed lately ? Have you done a windows update recently & finally when was the last time you blew the dust out/give it a good clean.
O yer & has Anyone else used the PC recently ?

Once you have the cover off to clean it Reseat everything.

I have downloaded no exe's or anything, i dont understand how it was fine one minute i restarted it just becuase i reset my router and modem and now it doesnt work.

Ill give it a dust but there isnt much in there.
