What device would you recommend if I want to run 5 monitors and 5 keyboard and mouse to 1 CPU


I am not entirely sure that this is possible, while you may well be able to connect all of these parts, you wont all be able to use the machine at once. There are vga splitters available for the screens and the keyboards and mice can plug into usb. The only way I can see this working is as a multi-room setup but just one person using the machine and going from room to room. (only using one monitor keyboard and mouse at a time)

My monitor will not stay on, it goes on sleep mode


Hi,
Your problem may be due to the sleep button in your keyboard may got struct into when you cleaned your keyboard.
Try to resolve the struct in the keys, if any.
Restart your system and if still your problem persists, then remove your keyboard and restart your computer and try with some other keyboard if possible. Once if you find out that the problem is with your keyboard, then replace the keyboard / service the existing one.'

I hope this is helpful to you. Please provide your ratings.
Thanks

When i try to boot it up, the monitor, keyboard, and mouse don't


So, this is a Desktop unit. My advice is this; Take the cover off and try to dust off as much webbing inside as possible.Make sure you take off the power cord when working inside. You will see a fan near the middle of the motherboard. This is your Heatsink/Fan for your CPU. I would bet many pennies this is overheated and may not boot again and if it does it will be unreliable. With your fingers and everything out of the way, plug the bare unit in and turn it on. Make sure the fan on top of the CPU is running. If not, quickly shut it off. I will help you more as you write back and we will get it running.

For the past week, when my Sceptre LCD monitor goes to sleep after inactivity, it won't restart immediately. The blue LED blinks every second or so; eventually, the screen begins to flash the display, and...


Hello there Jake.

Here's your geek-steer ...

== CLARIFICATION ==
  • When you say "sleep", are you certain it's sleep mode, as opposed to hibernate?
  • "...it won't restart immediately." ... you do mean of course AFTER you've given keyboard or mouse input, right?
  • "...the screen begins to flash the display" ... literally flash, as in strobe? Or do you just mean flash, as in "shows".
  • "...Sometimes the whole process takes five minutes, sometimes an hour." ... ???!!! If it takes anything longer than few/several moments, that's very abnormal, even if hibernate mode.
  • "...I can't find the documentation." ... not important, at least not at this point.
== SUGGESTIONS ==

A. RULE OUT THE SIMPLE FIRST.

1. Shutdown
2. Turn off PC and monitor
3. wait 5 minutes
4. unplug all cables/cords connected to monitor (both ends)
5. inspect/clean connect points
6. reconnect all cables/cords
7. plug monitor back in
8. startup system
9. try to duplicate problem

B. CPU HOG.

I'm curious to know what all your "Processes" are doing during this very delayed period of time. By knowing that, you can see which one(s) are running, and which of them are probably crunching hard at the CPU, which MAY explain the delay (I don't know about an hour, but minutes ... yes).

Do you have a "Processes" monitor utility of any kind? If not, get SysInternals' "Process Explorer" (no installation required, just unpack and launch). Make sure at least the "CPU History" item is included in the column header (View > Select Columns). Once launched, allow it to sleep.

Just as soon as able, after it comes out of sleep, review Process Explorer. What, if any, processes are hogging CPU? Post that back, and I suspect we may be a lot closer to a solution.

C. MONITOR FAILURE.

You might also hook up this monitor to a "known good" (functioning properly) PC with like "screen saver" and "power options" settings. If problem not encountered, you can at least isolate the problem to solely the monitor. However, if the only time you encounter problem with monitor is isolated to when coming out of sleep, this is likely a long-shot.

Good luck Jake, and please do post back ...
  • to let me (and interested others) know how things worked out,
  • to provide clarification or feedback.
  • if you have any further questions,

PC shuts down while running Windows


Attempt to boot the machine in Safe-Mode.

While powering up continuously hit F8.

You will get a Boot Option Menu, Select Safe-Mode boot

If you can get into safe-mode I would suggest to try doing an online scan, as it sounds like your issue could be related to malware:

PC stays in Sleep Mode and Keyboard and Mouse doesn't work


Well that's kind of a loaded question.
There is several things that can cause this to happen.
1. The CPU died because the cpu fan just died and burnt it out.
2. The Ram is bad which I doubt.
3. Somthing happend and burnt out the motherboard sometimes we get insects that climb inside our computer and go onto things and alot of stuff in the computer that can be grounded by a bug or whatever and burn out our computer I've had it happen before.
The monitor is fine it's just blinking because it's not getting a signal from the P.C.
You can try to unplug the PC and plug it back in and try again or even check in the back on the power supply there is a I/O switch make sure it's on.

Goes to sleep


Hi

Pls check the power option settings in control panel.

Also pls check if the power management options for keyboard and mouse in device manager are enabled or not.

Pls try to create a new profile and check if the sleep mode is working in the new profile.

Pls try a System restore if the above steps don't work.
