i have a compaq presario desktop that want go into windows. Its starts to boot up and then goes to a blue screen and shows this stop error
oxoooooc1f5 it even does it in safemode.

what operating system

It's windows vista

Try a system restore if you can get into system or a repair install if not using an install disc

Uhmmm. I don't know what error code and google is not bring up anything. If you have installed any new hardware, try removing it.

If you can lay your hands on a copy of Windows 7 do so and then read this;

How to work around Stop Error 0x0000C1F5 on a Windows Vista-based computer

wow very good answer to that.I read that and that is very interesting.

Thank you Maverick.

would imagine a repair install would work if you have vista disc, if not a full install and recovering files in old folder (i would back up just in case)
