I'm a newbie andknow very little about computers except how to use them. My PC (VPR Matrix 1800 - Windows XP) was running completely fine with the exception of losing time on the clock for the last couple of days and now all of the sudden I have no signal to the monitor and no pwer to the keyboard or mouse. I have switched out the monitors, keyboard and mouse and they still don't work (they work with my other PC). Also, there is no beep when powering up. Any advice that an ameteur could handle? I have opened the case and it seems that fans are working, everything is in place and attached and it's not super dusty or anything inside. I would appreciate any help - I know it's not always easy helping an ameteur but I would really appreciate it. I just don't have the money to spend on taking it in somewhere right now. Thanks!
