After about 5 minutes of mining with GUI miner its turning my computer screen off randomly and then i have to restart my computer to get it back, is this a common problem?

Might need more information about what you're mining with. With the information you provided, it could be that your graphics is either overheating or the drivers are crashing (due to over/under-clocking problems).

Dual Core E5300 @ 2.6ghz
ATI 4850 graphics card.

Download and install Speedfan. Its free. Then run Speedfan and monitor all your temperatures. From there run your miner and see if it overheats. If it does, then try manually turning up the fan. Additionally, if you have Windows, you could see if you have some ridiculous time for Sleep Mode.

Either your video card is dieing or you need to add some vcore to the video card.

I take tips

yea sounds like video card is dying - if it's not an overclocking issue. Turn everything back to factory and see? Otherwise need more info
