Hi all, I've found this site a while back and now I'm finally posting. I'm mostly a new at overclocking, but I got the basics down. I need some help with overclocking my CPU, an Athlon II x4 620. Its default multiplier is 13 and base clock is 200MHz, making it a 2.6GHz quad. I have a Gigabyte MicroATX with only one PCI-E slot, was using the integrated 785G Radeon HD4200. Also have a 400w Rosewill PSU. I had the base clock up to 250MHz putting it at 3.25GHz. It ran stable. When I installed a 9400GT, it appeared to run fine, until I ran CoD4 for under a minute. Almost instantly it would blue screen once ingame. My question is why does this happen? I think it's the underpowered PSU, some sites say they use up quite a bit of power upon using them. Or could it be the voltages? I don't really know about voltages, so I left it on auto. I think it's at 1.2 or 1.3v. Can anyone give me an insight as to why it is bluescreening? Thanks for any help.
