CPU: AMD Phenom II X4 965
Motherboard: Biostar TA790GX A3+
Graphics: ATI Radeon HD 4770
RAM: 4gb Corseir
Windows is constantly freezing up, seemingly at random. Sometimes 5 mins after boot. Sometimes an hour. The mouse pointer stops responding and task manger won't open.
I've installed all the updates from Microsoft and also Biostar, ATI etc. But it has made no difference.
I've also tried a clean install of Windows on a formatted hdd. Same problem.
Eventviewer shows the following from about half an hour (I think) before the last crash:
"The ATICDSDr service failed to start due to the following error:
Windows cannot verify the digital signature for this file. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source."
This error appears 20 times in the space of 1 minute. Any relevance?
Also, this might be completly unrelated but I have 2 updates that refuse to install.
1. HID Non-User Input Data Filter
2. Microsoft Mouse and Keyboard Detection Filter
I am finding this very frustrating as I can't get any thing done on my machine. And I really don't want to have to revert back to Vista!
Any help would be greatly appreciated.
