Acer 5820T

Windows 7 Home x64

CPU Intel Core i5-460M, 2.53GHz, 3MB L3 cache

RAM 4GB DDR3

Intel HD Graphics

500GB HDD

problems starts after first automatic update which failed.

computer takes a lot of time to start-up.

now i`ve got system updated after downloading updates from Download Centre.

nevertheles system usualy freez after start-up.

after rebooting into Safe Mode and running Advance System Care system sometimes starting as it should but the proccess is very slow. it usualy freez after WiFi is established.

i created a new user account and first login/startup in new account is always fine but after re-start it freezes again

i changed a few services from starting automaticly to automaticly-deleyed and surprasingly it did not freez - at least for now

anyway, a window with more 47 updates pop-up. I`ll run the installation and post the outcome soon.

So...

at first i run update Windows6.1-KB2510636-x64, I found this update in some post; as i remember this update is a HotFix and my improve booting time; then i checked for system updates and it come up with 62. Automatic instalation was succes for 55 and failed for 7 of them

Errors:

800B0100

FFFFFFFE

800736CC

All of above with note: Windows Update encountered an unknown error.

and below note that Windows can`t update important files and services while the system is using them...

I clik Restart Now and after a while of configuration Windows Files start to load and Startup Repair window come up with info that computer was unable to start. After restart it froze again, so as before Safe Mode and Advance System Care. After restart i noticed that HotFix update and all those automatic has been retrived so i`m back where i was...

any clues...?
