How will I know if my virus scanner is really working?

My CD/DVD drive cannot read the disk I inserted.  

I don't frequently use the drive  and I don't know why it's not working now.

Any help will be greatly appreciated.

Thanks!

I bought a new video card couple of days before and I have a problem. When I installed the video board in my MoBo and rebooted the system, the POST (power on self-test) was terribly slow.

Earlier it paused for seconds, now it needs around 10-15 minutes. I tested the video on my neighbor's PC and it worked with no problems. What is the reason for this? Do I need to change my MoBo?

I use my computer basically for gaming. Whenever I play for 8 hours or more, the computer does not boot the next time I use it.

However, there are times that it boots but then suddenly turns off after several minutes of usage. I changed to a different powersupply before but the problem still persists. What could be the problem?

Hi everyone,

I got terribly scared in the middle of the night when out of the blue this error message pops-out on me:

System Properties

“There was an unexpected error in the property page:

Catastrophic failure (0x8000FFFF)

Please close the property page and try again.”

The move that caused the error to appear was simply trying to start up System properties from Control Panel.

Why is this catastrophic?

And how do I find out what caused it?

Please help, I would greatly appreciate it.

 When I want to start my computer, it needs to restart two or more times. How can I solve the problem?

I want a tool that can control the bandwidth consumption of all applications.

I have tried using a splitter but some applications and programs don’t show up.

I need something that can control all traffic.

I have TMG 2010 and ANS ISA 2006.

What are the features that the Operating System of a Hand-held computer and Time-sharing system should have among the following: Batch programming, Virtual Memory and Time Sharing?

How can I view the BIOS version of video card? Please discuss for me.

Can you tell me which is more compatible with my IDE Hard Disk in terms of faster data transfer? The SATA out cable or the SATA II HD using a USB cable?
