Re: My pc powers up...but my keyboard,monitor and mouse...
I have encountered the same problem. Mine has something to do with the RAM. I replaced my memory and it solved it. Try checking your CMOS battery, it might need replacement as well. I hope this helps.

Once the monitor shows "no input", indeed the mouse and keyboard are pretty useless, even if the are working, as you cannot see they are working. If the monitor power light is on or flashing, but nothing displays, borrow a monitor from a friend. If that works, your monitor needs replaced.
No signal at the monitor indicates (if you know the monitor is working ok) a failure of the graphics chip or graphics card, The lack of indicator light on the num lock LED and the lack of power to the mouse would indicate that there is a major issue with the motherboard. you can try using another monitor to confirm the problem lies with the graphics, and in the case of the keyboard and mouse, swap them for a usb version, if they work, the Ps2 ports are probably damaged. I'd be thinking of replacing the motherboard
Your system is failing the POST, I think. You'll need to troubleshoot it by opening the case and unplugging everything but the CPU and memory and video. Now power it on. If there still is a problem, try removing one of the sticks of memory. Once you isolate the problem, you can replace the part that has gone bad.
Warning: Before Doing the Below Steps don't forget to Unplug the Power cable, monitor cable, keyboard and mouse and any other device connected to your computer.
Do the following Steps.
Step 1: Open the PC case(not your monitir) Step 2: Locate the CMOS battery on the mother board.
Step3: Remove the Battery and leave it for 4-5min, now put the battery back in its proper place.
After doing above steps now you can connect the power cable, VGA cable, keyboard,mouse etc... and switch on the computer and see if you are able to get display. If still you find the same problem you can try removing RAM from RAM bank and clean it with a brush or a cloth ,both RAM and RAM Bank. Now Put back the RAM and switch on the computer.
hi...if u can read " no input signal" from ur screen, this means that ur monitor is ok.. Look if u have power buttons on ur keyboard.. try to wake it from there.. some pc may have shortcut keys to bring back the pc... look @ ur pc docs on the internet for more info... However if it's a hardware issue, it may be that ur RAM memory needs to be cleaned
the way the kvm switches works is you have your mouse/keyboard and monitor plugged into the switch then you have the cables connecting to where you would have your mouse/keyboard on your pc, youll be using the same keyboard/mouse and monitor to run 2 pc's. there will be rather a switch to move between the pc's or like the 1 i use i have tp press ctrl the number 2 twice.
try to connect it with other keyboard,mouse and monitor....if they will run, the keyboard,mouse and monitor may be defective or damaged..but if they did not run properly,, maybe somethings wrong wit your unit... try to connect it first and see whats the result... please tell me what are the results... you may post it here...
Your HP notebook PC probably has a VGA (aka HD-15) connector. Check page 16 of this PDF to make sure - connector #2 is the VGA connector.
Your Compaq monitor also has a VGA HD-15 connector, so it should plug directly into your laptop's port after unplugging it from the other PC.
You will still need to plug the Compaq monitor's power cable into a wall outlet for power.
If you are going to share this monitor between your notebook and the other PC, you may want to consider purchasing a Keyboard-Video-Mouse switch (known as a "KVM switch") - there are many different models - you will need one with VGA, and whether you need USB or PS/2 keyboard/mouse connections depends on what your other PC's keyboard and mouse are.
