I think the issue is your monitor. If the monitor constantly says Power
Save Mode and not let anything else display then the monitor might be
bad. See if we can isolate the problem by the steps below.
Try booting up in Safe Mode and see if the monitor works ok.
Turn off the computer, then hit the power button to turn it
back on and immediately start hitting the F8 key repeatedly until you see SAFE
MODE. Take the Safe Mode option and let it boot up. Safe Mode will look
different to you, the screen will be darker and the icons bigger, this is
normal. If it works ok in safe mode then the monitor is ok and we might have an issue with a setting.
Try connecting another monitor to your computer. Borrow a monitor
from a neighbor, friend, relative or co-worker and connect it to the
computer. If the Borrowed monitor works ok, then your original monitor
is bad. If the Borrowed monitor does the same thing as your original
monitor then the issue is with the computer (possibly the video card).
Make sure you have the cable that plugs into the back of the computer from the monitor screwed in tight. Also make sure the cable on the back of the monitor is screwed in tight and also that the power cord on the back of the monitor is pushed in all the way.
I'm almost certain you're not in standby mode. Does the computer stay on when you get the no signal message? Do you hear the fan blowing, do you hear the disk drive spinning? If not, I think your system has completely shut down. I'm thinking maybe a virus or some hardware/software conflict is stopping it from completing the boot cycle.
Try getting into the Bios or System Setup to see if the LCD Stays on and the computer stays on. Turn the computer off, then hit the power button to turn it back on. Look at the lcd screen and it will tell you what key to hit to go into the Bios or System Setup. Go into it and let the computer sit for 10 minutes or so to see if it shuts itself off.
If you are successful with the computer staying in the Bios or System Setup lets try getting into Safe Mode and see what happens. Turn the computer off and hit the power button to turn it back on and immediately start hitting the F8 key repeatedly until you see the SAFE MODE option. Select the Safe Mode option and let the system boot up. Safe mode will look different to you. The icons will be bigger and the lcd screen darker, but that's normal. If you are able to see the desktop in safe mode just try opening up MS Word and maybe let it sit for a few minutes to see if it shuts off.
If safe mode was successful, then try booting it normally. If it fails, we know we've got an issue.
Choose within this options with regards to your monitor:
1. You could replace your monitor with a new one.
2. Or you could send someone or send it to a technician to repair your monitor.
Boot Up Problem:
1. Try checking the Power Supply Unit (PSU) if it give out 12Voltz. If not you could replace it with new PSU.
2. Check the motherboard if there are some blown out Capacitors. If there is, send it to a technician to replace it. If none, replace your Processor. That is the defective. That causes the boot up problem.
On boot up screen. Of course it will not show a boot up screen because there is a problem on your monitor. And so, there is also a problem on your motherboard (Processor or Capacitor).
Hope this might help. Thanks.
was anything else installed like memory
does your screen just go black or actually shut off
try and click f8 continuosly while restarting see if that will get you into safe mode
If not you may need to reinstall recovery again
There could be a number of causes. Do you hear any beeps when the computer starts up?
Try seating all the chips in the motherboard. That means, apply pressure to each individual chip on the motherboard with your finger or thumb. The goal is to make sure each chip is securely attached to the board.
Sometimes, heat or new h/w installs partially "pop" some of the chips out of the motherboard - causing the circuitry to be disconnected...
