Feeling bad here. I might be a newbie here but I have enjoyed a 5 year relationship with CCleaner that was born out of frustrations with my then hard drive wiping solution, [competition product name removed] However since Windows 10 came out CCleaner has been installed but, effectively, switched off by deselecting everything as I have been suffering the 64 bit memory overload issue too. I have kept it installed so that I would be informed of an update which, I hoped, would solve this problem.
Today I was happy to see an update which I duly installed and ran (on my 2 week old recycle bin) only to see memory spike to 7.8Gb twice then black screens (dual monitor), quick "3 fingered salute" and I ran my System Explorer with only 1 screen returning, me being logged-out (???) and returning to a visible reboot of most my system applications. Naturally I restarted then looked to uninstall CCleaner to find it missing from Revo. Through Control Panel I started to uninstall to find my system freezing again. Finally it returned and I completed the uninstall. [Competition product endorsement removed]
Please find the root of this problem and fix it. Here's my system information for you.
Intel i7-4710HQ - 2.5GHz
8 GB RAM
Intel HD Graphics 4600 / Nvidia GTX 850M
Basically everything that should be dead-centre for compatibility. Over to you. I will monitor this thread and really hope to hear positive stories again soon. Thank you for everything to this point. I hope to be able to recommend you again to everybody who asks (i.e. plenty).
Good luck
