IOgear gcs62 KVM Problems

I have been using 2 WinXP pc systems for over a year. I use a GCS62 IOGear KVM 2 port ps/2 with the 2 system. For awhile I been having issue where the display wont come up when I boot up a system or restart a system. Then yesterday all of a sudden on my main system the display just went out on me. I switch over to the 2nd system with the KVM and it was working fine. I tried to reboot the main, but the display just will not come back up. I unpluged everything and power off everything I can. Nothing I do can get the main system to boot up or display. (Even when I plug the monitor, mouse, keyboard all directly to the main pc) I gave after that, thinking that video card was shot. Come back the next day and boots up and the main system boots up fine @@ however now the 2nd PC wont boot up and is having all the issues the main system have the day before. I went out and got a brand new KVM, but that didnt help any. All day today, I just cannot in any shape or form able to boot up the 2nd PC, while the main PC acts like nothing happened at all.

Anyone have any input on this? any help would be great.
