ECC is a type of Memory that is used mainly in servers. So having the ECC Mode switched off only means that your system doesn't use ECC RAM. This is correct.

CPU Selection Mode: single
The choice is OK ?

Well provided that there is only 1 CPU Fitted to this system which is normal for desktop systems it's perfectly OK. Some Systems particularly Server Systems have more than 1 CPU per M'Board. The most common ones have 2 CPU's but there are Quad CPU M'Boards and when you get into the Blade Server Boards you can go as high as you like but for normal systems 1 is right.

I boot with Ultimate Boot CD but I don't know which test I muss Do? Would you be so kind to tell me ?

Seems like you have done what is necessary here tested the RAM and the HDD which you could have done from the Ultimate Boot CD.

you I have install Google Chrome, How i can know that this was i bad idea ?
I can i deinstall ?

This could be what the problem is and yes you can uninstall it, though here I would suggest uninstalling it from the Main Menu under the Google Chrome Uninstall Option Listing rather than the Add Remove Programs from the Control Panel.

Thanks a lot, can you help me ?

I would just Backup any Data that you have on the system then blow away the OS and load from whatever you have as a Recovery Option.

If you have a M$ Branded Install Disc as apposed to a System Makers Recovery Disc you could try a Repair Install which may work

But honestly I would just wipe the HDD unless there is a Recovery Partition on it and start from scratch it's faster and easier.

Do you meant to reinstall ? I musst be honest i have not all CD installation .......

Thanks a lot for your helping and i'm sorry for the time that you wasted

But from past experience when Windows gets messed up so badly that it can not be fixed in an hour or less I find it much easier to just Wipe and do a clean install.

Actually if you have had any form of Windows running for more than 18 months tops it's a good idea to reinstall the OS to a blank HDD.

It's just faster to cure problems and get things working again most times. Windows fills up with junk and slows to a crawl over time and the only solution when this happens is to wipe and reinstall everything. It's also a very good idea to do regular backup's to prevent Data Loss when Windows falls over and stops working.

But you can try a Repair Install if you have a M$ Branded Install Disc as apposed to a system makers recovery Disc. With the System Makers Recovery Disc you generally speaking do not have the Repair Install Option available because it's not a full version of Windows.
