I have two RAMs of 1 GB each installed in my PC both are of Kingston. Some times they work fine but some times my PC shows total installed memory of 1 GB only. What is the problem in it?

I have removed both and put them in different slots but even then the same problem occurred.

Guide me with the solution please.

I have a problem regarding Restarting of PC. When I restart my PC from the windows it shows nothing, the display is gone just a black window appears. However when I push the restart button on my PC it works well. Don’t know what is the problem, hardware or software.

I have an old Pentium 4 processor, an Asrock Conroe-1333 D667 motherboard, an ATX case with 400w Power supply, and a DDR2 RAM module lying around the house, thought it was such a waste, so I decided to bring it back to life. I hooked everything up, I knew  it was running because the heat sink fan was spinning as it should but there was no display on the monitor, no POST and no beep.

The motherboard had onboard graphics card so i tried plugging in my working GT220 graphics card from my current rig but still no display. I've tested out every hardware except for the motherboard and processor as I've got AMD build from my other computers.

Any suggestions to resurrect this old setup again?
