Most former generation cards and motherboards in towers use the notorious PLCC (plastic leadless chip carrier) to mouont large scale integrated circuits. These vary in size from postage stamp to checkerboard squares, and their inherent design makes the socket bow outward, with chip mounted, on all four sides--just enough to compromise the middle contacts on all four sides. The best solution is to optimize what contact there is, by spraying around the perimeter of the socket where the contacts are with plastic safe lubricating contact cleaner and then re-seating the chip by pressing it into the socket with a firm thumb press; you'll feel it move. I do this as a matter of routine maintenance with every such I work on.

Actually during start-up there is a slight delay before the HDD & OS is detected by the CPU. Normally all monitors slip into power saving mode within 10 secs of inactivity of either mouse or keystroke. This inactivity is read by the monitor which promptly switches to power saving mode. However the moment the HDD LED starts blinking, the monitor wakes up & starts displaying. This power saving mode in most of the flat screens is only associated with movement of mouse or keypad. This does not register till the CPU starts up & thats why the monitor switches over to power saving mode till it starts receiving signal from the CPU. It is a normal behaveour, so don't get worked up over it, plus you can always hit the Auto set feature on the monitor after booting the PC completely. ( I think the time out for the monitor to enter power saving mode is only 10 secs). Hope this helps.
Sounds like to power settings were set too low. Restart the PC, before it gets to Windows press F8. This will send the PC into SAFE mode. You'll get a menu of which SAFE mode to select, just select SAFE mode with networking. Once in SAFE mode, go to START, Control Panel, Power Options. From there select new settings. Since this is a desktop, I would make the settings very long. Good luck
Dell monitors automatically go into power-save mode after a preset
amount of time when the computer is inactive. The Dell monitor will go
completely black, instead of showing a screensaver. This doesn't mean
that your Dell computer
has shut down. Instead, this allows your monitor to essentially turn
off until it's needed again. You can change how long it is before the
Dell monitor goes into power-save mode by changing your display
any key on your keyboard or move your mouse. Either will turn off
power-save mode. Alternately, you can press the power button on your
Dell computer tower or laptop.
any key a second time if the monitor goes from power-save to stand-by
mode. Stand-by mode allows the screensaver to appear.
your user name and password into the login prompt if your computer
requires a login. Press "Enter" to begin using your Dell computer.
the display settings on your Dell monitor to prevent your monitor from
going into power-save mode prematurely. Right-click anywhere on your
desktop and choose "Properties." Click the "Screensaver" tab and press
"Power." Beside "Turn off Monitor," choose a time amount from the
drop-down list and press "Apply."
I am having the same problem . The system is starting up and th epc entering power save mode. I have a Hp pavilion f1503 model monitor. I hit the power off button on the power surge to shut the entire power off. I turn the power surge button back on. Sometimes it works. Or have to hit the power on button to reboot.
