This has been happening since last night, 8:00 P.M. My specs: Quad core AMD A8-3800 8GB DDR3 RAM 1TB HDD Genuine Win 7 Home Premium AMD Radeon HD 6550D Other things to know, I installed "Google Talk" and removed it, "Sony Vegas Pro 11.0" and still have it, deleted "Skype" because I THOUGHT it was the problem, and installed "ooVoo." I made a Win 7 64-bit repair CD on Friday... But back to the freezing, I can move the mouse, but everything, task bar, desktop gui, EVERYTHING goes not responding, Then several minutes later Win tells me explorer.exe is non responsive, I kill the process, no help but several minutes later explorer comes back alive, and everything is nice pretty and dandy. WTF, I did not buy a $1000 for this. I'm a advanced user, repaired computers B4, this is just weird... I'll do anything, Malware-bytes came up clear and so did my McAfee. I WILL ANSWER ANY QUESTIONS, JUST ASK!!
