For the past four days my computer has been restarting randomly. After 10, 5, 30, minutes or even after some hours. Strangely enough i don’t get any error messages or notification when this happens.

After every shut down, a message "How do you want to start Windows" when the computer restarts itself.

Basically, i use the computer to surf the net using Firefox, play a game “Hitman Blood Money” and to play audio and video files.

I had a feeling the problem was the video card, i checked it out, and it was hot, it was kind of getting heated up. I bought a new video card and had it fixed. This time round my PC would blink for a second and then shut off.

This is a three month old Celeron desktop computer. It all started about the time I started making new user accounts but every time I reboot my computer I hear continues and annoying sound that really bugs me off. And when I'm using my computer it suddenly restarts.

And when it restarts, I hears the annoying sound again. I don't know where it came from. I checked inside the CPU but I think its all okay. So I reboot my computer again to try it once again but nothing happen. My friend told me that could be the memory. How will I fix this problem?

I bought a new wireless adapter two weeks ago. I followed the instructions and successfully installed the adapter. Everything worked fine until yesterday. It started giving error messages and now it won’t work. It gives out a steady red light all the time and the PC notifies me that the adapter is not connected, which is true. I have cleared the cache, tried it different USB port but the problem remains unsolved.

I concluded that the adapter was the problem and I bought a new one, Belkin Wireless G Plus MIMO USB Network Adapter – F5D9050. I installed it as per the instructions. Everything seemed to be functioning normally until I tried to configure the connections.

How to replace motherboard to a computer?

I bought a desktop computer with an AMD Athlon 64 3500+ processor, 200 gig hard drive etc. It recently started displaying very wavy images on my screen. I turned it off for a while but now when I turned it on my computer, the fans just start up and keep going and no image is displayed on my screen.

I replaced the graphics card and still have the same problem but I didn't hear beep sound or anything. I was told by my friend that it was the motherboard problem. What should I do to fix this? Does anyone know this kind of problem?

I have been through the same problem ever since I displaced my desktop computer from one room to another. I was used to that in the past but now these vertical lines appearing on my computer screen are becoming too annoying. For a start I used to tap the screen to make the line disappear but recently the problem has become too complex.
