Basically i don't know how to write this in the easiest way.
Recently my computer has been a bit dodgy during the start up screens, every time it is turned on it seems to restart numerous times, sometimes it resets within a few seconds, sometimes it shows the first screen.
From reading similar problems on the internet i decided to takethe CMOS button out, which seemed to fix the problem until the next day i turned it on and it had the same problem again.
As im sure you can imagine i don't really want to open my computer every day and removed this button and put it back in (due to it being under 2 of my cards)
If you need any more details just leave a message and i'll try my best to answer them.
Cheers for any help
