Any help on this would be greatly appreciated. For the past two months or so I have been getting random lock-ups and shutdowns of my pc. Most of the time I get a blue screen of death but it goes by so fast I cannot get the error info. I have been told it could be a power supply issue or a graphics card issue, or a driver issue, etc. My first reaction was that the power supply was bad/not powerful enough because the top fan of my case does not turn unless you start it manually. Then when it is going it will kinda sputter a little and stop. On a whim I tried removing my graphics card I had bought and using just the integrated card on the mobo. I thought I had my solution. the pc ran great for a week straight with no problems. then I put the graphics card i purchased back in and it was doing the random shut downs again…problem discovered. But alas, today running on the integrated card, I got two lockups/shutdowns. Does this sound like more of a power supply problem to anyone? I know psu’s are not extre,mely expensive. But I guess one question would be if the psu I got is powerful enough. if anyone can look at the specs i give and let me know if the 750W PSU i bought is enough or if it souinds like it may be going bad. thanks greatly for any help. Here are my specs:
