I have a problem with my PC. It won't "wake up" after sleep mode. :??:

I've tried a few things, but nothing has worked.

So I would be really happy to get some help! :)

I accidentally put my computer into Sleep Mode,
Even though I meant to turn it off entirely.

Now 3 nights have passed and I've still NOT been able to get it working again.

When I press the power button, some lights turn on and things start spinning.

The monitor switches on, then says "No Video Input", "Returning to Sleep Mode".

I've opened the side of my case, so I can verify that things do indeed turned on;
at least to some extent. The screen however, remains blank.

There are also no beeps of any kind either. The fans are all spinning properly.
The yellow light on the motherboard is lighted.

The blue light on the power button is blinking as it usually does.
The lights on the keyboard, (I.e. Numlock) isn't lighted up as well.

My monitor is a Philips, and I know it's working properly because I hooked it up with my laptop to check.

I've tried :( :
- Restarting, many, many times.
- Unplugging, and then holding the power button for 30 secs - 1 minute as some forums suggested.
- Unplugging the power cords and plugging it back again.
- Turning off all the switches, and leaving it for one night to cool.
- Cleaning the entire inner case.
- Searching the forum for similar cases.
- CMOS reset.

But nothing is working.

Tonight, I'll be unplugging everything and leaving it on to cool again.

Help please?

Often a monitor will get "stuck" on the last source input it had a reading on, or defaulted to. If your monitor has a source botton or selector try pushing it to force it to cycle through the inputs again, but only after you are certian there is a good input signal.

Thank you for the suggestion. You're almost right!
I finally gave up and called the a Tech Support and he told me my RAM support from a memory CLOT.
So we solved the problem with a new RAM replacement.
