- I scanned my pc for viruses but nothing found.then I formatted my problem is solved but when removed RAMs n inserted again it was not working.

- Now my pc works with one of the RAMs.but when I inserted second RAM, it beeps.I tried again about 6-7 times.but still it beeps.On the other hand it works if I insert the first RAM only.

CPU doesn't have ram slots or any other slots, only motherboard have memory slots.
CPU + board + RAM + case + other hardware = system.

Bad memory can cause bad pixels and it seems one of memory stick is bad. Download memtest and put it in thumb drive or burn it then run memtest.

You know the real meaning of peace only if you have been through the war.

Why did you remove RAM to fix a problem with the display? The beeping means you didn't re-seat the RAM in the slots correctly.

You're supposed to ground yourself before handling the inside of your machine. You might of discharged a static shock that killed that module.

By the way, you can't install RAM to a central processing unit.

If the machine works with one stick of memory then try it in the other slot to verify the slot is good, then just replace the memory. The test is just a tool to see if the memory is bad, but you already know that either the memory or the slot is bad since the memory previously worked, it is not a compatibility issue. If the slot works then you already know what is bad, just replace it.

Note of terminology:
Ever since the entire Central Processing Unit (CPU) was put on a single 'Chip', that chip is now called the CPU and the entire unit (everything in the computer's main box including the 'box' is referred to as the 'System' or simply as the 'Computer'. The CPU is generally made by Intel or AMD and is plugged into your motherboard sitting just under the largest heatsink usually with a fan on top of it. WAY back when computers were made up of many circuit boards plugged into one or more larger boards or 'chassis', the entire unit (sometimes as large as a room) was referred to as the CPU. The very first computer actually took up 3 entire floors of a building and took weeks to 'program' by a crew walking around with clipboards to each 'station' to set switches (It used vacuum tubes and I think it was in the 1950's) and that computer was 'dumb' compared to a 'Bomar Brain' (an early scientific calculator in the 1970's).

You have to be a little bit crazy to keep you from going insane.
