Hi folks. I'm really hoping you can help me diagnoise and possibly fix this issue I'm having. A month ago I formatted and did a clean install of windows 7 on my computer. An HP Pavillion a6530f. The only thing different from that model is that I installed a 9500 GT a couple years ago for gaming purposes. I woke up a couple days ago and there is this slight ... hesistation every second or so. I wouldn't even notice it except when gaming and watching video. It's very regular and just seems to halt the game or video ever so slightly. I thought the issue was with the internet connection, so I hardwired the computer and still had the problem. I then thought I might be having video card issues and I lowered the settings as low as I could. The problem did not go away. I also noticed that under the nvida control panel there is a graphic that turns. This graphic was hesitating as well. I have scanned and re-scanned for malware and viruses. I have booted in safe mode (the problem went away as far as I could tell). I have done all the scans and hardware checks I can think of and everything seems to be running optimally according to the computer. Temps are low. Help me. I implore you. I am out of ideas.
