From reading the previous problems with this Graphics Card Ive gathered that first of all I need to install an additional fan which shouldnt be too much of a problem. I'm pretty sure my graphics card is overclocked too, I read something about going into the BIOS and changing it, the only thing is I dont have a clue how to get into the BIOS and change it? Im not that clued up on it, so if anyone can help me with this I will be truly gratefull. Oh and what driver is recommended.

Ive had my pc since October last year. The first time the problem occured was when playing GTA Vice City and the pc rebooted itself. It did this on numerous occasions. Then eased off. Then just now the problem has started to occur again, Once when playing CS but I also had CM4 running in background. Now its happened 5times in 2days whilst playing Americas Army and Im getting a bit Peed off and have put it down to the climate. I was told previous it was a virus or problem with my RAM but reading other people problems on here it must be the Graphics card. So like I said any help would be great. Cheers

OK well with the BIOS you can reboot your computer and when the computer starts back up at the point were it displaying the memory and the hard drives right when it first comes up hit the Delete key twice your computer may be different but if it is like my laptop then when you will need to call that company or look on the Internet for which key you need to use. Drivers I would first try the latest Nvidia drivers from there site. You may also what to have your power supply checked out as this sounds a lot like what my computer was at one time doing and it was the power supple that was causing the problems. Hope this helps.
