I have used PAK for a few years. First was to find out why my computer wouldn’t connect to the internet. They fixed it by rolling back my latest anti virus software. Second was free advice given to me on moving files between my old computer and my new computer. Last was for blue screen problems. My Windows 7 computer would blue screen for no particular reason. I didn’t want my computer upgraded to Windows 8, I just wanted my computer fixed. After 8 to 10 tries, replacing memory and mother boards, the issue lessened but never went away. But, new issues were introduced. My computer now will just power off for no reason, not even a blue screen. It won’t always start, I have to keep trying 2 or 3 times for it to startup. Now about half the time the computer will not power down. Once it hangs up I have to hold the power button down until it does shut off. I upgraded to Windows 10 which stopped the blue screens completely but all of the other issues are still there. I don’t think I will be back.
