Hello, everyone! I recently installed an ATI Radeon Sapphire 7750 HD graphics card on my Dell Inspiron 560. I purchased this card because I though I wouldn't need to upgrade the power supply, but my computer has started to act strangely. Yesterday it rebooted without warning once, and now it has done it three times within a short time span today. The peculiar thing is that I wasn't doing anything particularly intensive to the graphics when it shut down; I was managing a few folders and searching on the internet. I played Arma 2 yesterday for a while without error and I really don't see how this could be related to the power supply because of these things. The stock PSU is 300 watts in my computer.
Based on what I have said, would you think it is a PSU problem or something else? All help if very much appreciated.
Computer specifications:
Dell Inspiron 560
Dell Inspiron Pentium Dual Core Processor e5800, 3.0ghz
300w stock PSU
