It's desktop.

lol popeye when i had that problem it wouldnt even turn on at 1 point and the cmos battery isnt hard to find on a laptop from my experience of changing rams on different computers the battery is usually located under the ram next to the network card.

Some laptops you have to remove the keyboard to replace the cmos battery, and they have started putting the second memory bank under the keyboard as well so if you want more ram you have to take it into a shop and strip half the computer just to put a stick of memory in, wonder why they would do that.

I reset the Bios (removed the battery from the BIOS for 30 seconds), removed one of my RAM (I had 2 each 2GB)
Computer started working. I can not understand one thing. Why when I put back second RAM computer does not work. It turns on normally but no signal is sent to monitor as if it was not even turned on.
Do you think one slot of RAM consumes so much energy that power supply cannot provide enough.

Get the Laptop Repair course. It might be helpful.

ok this might be risky but try to remember the monitor set up. but first
take that memory out. if it works. then nevermind this. if it doesnt then.
remove the screen cover. and there should be a rectangular chip. check if its connected correctly or if its broken chances are if it doesnt work even if that memory out. its broken or disconnected. if it works with memory just buy a newone.

Try both sticks of ram one at a time in both slots, if one doesnt work bin it and buy another.

I think TheSwarm has experience in that type of problem. I also have such problem. Yes the motherboard battery causing the problem. I like to suggest you pick up the battery from mother board and just clink it with a rubber or eraser or a piece of paper an then reinsert it. If this trick does not work then it might be your RAM problem. You then also do the same type of cleaning of RAM . At last to a tech. I hope you will do it yourself. Best of LUCK.

Reading his diagnostics, at this point I'd look at the stick of ram he pulled out. He said he reset his Bios and pulled a stick of ram and his computer "worked" fine. I would swap the sticks and see if you have the original problem. A couple of things come to mind. If the system boots and works fine with either stick installed but not both, verify that you don't have a socket problem on the Mobo. I'd do this by placing only 1 stick in socket A and try to boot. If your successful in the boot attempt move the stick to the other socket and repeat. Personally I'm thinking you have a bad stick of memory rather than a bad socket. Let us know what happens.
