Hello 7625965
but before going specific I'd like to make general health test for my computer.
A "general health test" is extremely vague.
Are you referring to a scan for existing malware on your system?
Or a security scanner to test for vulnerabilities?
Or maybe a scan of your hardware and OS, to make sure all is running smoothly?
I would suggest being a little more specific about your issues,
and possibly following the directions on this page.
This should get you better results here at gTg.
Thank you and have a great day.

"A scan of my hardware and OS, to make sure all is running smoothly" is my first preference.
I"ll check the link also.
Thank you.

When quoting another users reply, please
try to keep your own reply out of the quote box.
I would say the best way to check your OS for issues would
be to check your system files first.
To do this use the built in System File Checker.
Here's how: Open a command prompt as administrator.
To do this, open the Start Menu.
Click on All Programs, then Accessories.
Right click on Command Prompt, and click on Run as Administrator.
Now in the command prompt copy and paste the text in the box below and hit enter:
sfc /scannow
If Windows finds any errors in your system files,
you may need your Windows 7 install disc to repair these.
Star with this, then post back and I will give you some more suggestions.
Thank you and have a great day.
