I will write this shortly. Any mouse i plug in in my desktop pc, at random times cursor freezes, but buttons work, and when i lift up my mouse and put it back on the table, only then i can move the cursor. It affects the games too. Very annoying. I searched the web without much luck. Any help would be greatly appreciated!

Yes.

First of all, forgive me my bad English. So, I am trying to fix my old pc, but It freezes at the POST screen all the time, I cant go to BIOS, or press any keyboard button. I have been fixing this thing for weeks, I searched all the web, but without luck. I tried almost everything: *Removing the CPU cooler. *Using Internal and External GPU. *Removing every single unneeded cables that connects to motherboard. *Swapping the ram slots. *Tried to turn on without keyboard. *Tried to turn on without video cable, when it turned on, I put the cable back, still no luck.. *When turning on without any ram, it beeps. *Tried different PSU. *Tried Clearing CMOS. I wanted to update the bios, but I cannot do anything on this PC. I think the fault may be in the ram stick, I have 2 ram sticks, with first one it doesn't show anything on the screen, the fans only spin (I am not using that stick). And I think if the second ram was good, it should show under "1024MB OK" something like: USB devices found..., etc. Or it may be fault with the motherboard. This pc was full of ants, bugs etc. but I cleaned it before turning it on... And one more thing: I bought new ram sticks, but I have to wait for them. If it works after I put in the new ram, I will tell you. But for now, it may be something else that causes this problem, so I would appreciate if someone can help me fix this.
