Monitor wont boot....

[SlayZombi]

Ok I have a problem here... whenever I leave home, I usually turn off my monitor but leave my computer on. When I come back, I turn it on and nothing happens. It tries to find a signal and fails. Then, I notice that the GPU LED is on, indicating a problem. This only happens when I turn it off for a while... any solutions???

have you tried plugging it into your motherboards dvi/vga port?

Try another monitor.

What gpu is it? Post your build. Is it a psu problem? Post your build Is the led green or red? How many leds are on the gpu?

There are issues with some computers not resuming from standby properly. To rule that out, or identify it as the problem (assuming Win7 - though 8 is probably similar): Open "Change power-saving settings" from your control panel, and pick (or create) a power plan that never puts your computer to sleep.
If then, when you leave it for a while everything still works fine, it's resuming from standby that's your problem. You might then be able to look into that more, or alternatively just leave your computer on a power plan that doesn't put your computer in sleep/standby... if you don't care about the additional power draw.

Here's what I have:
AMD FX 8320 8-core
R7 250 1gb DDR5
16 GB Vengence low profile RAM
7200 RPM hard disk
Windows 8.1 Pro
Asus M5a99fx PRO R2.0 motherboard
My 750 watt PSU is from an old computer

The led light is red and stays steady like a red traffic light. And it's one led.

I don't have one, AMD CPU's don't have integrated graphics so it doesn't come with one.

I have Windows 8.1 and already did all the power plan stuff. The memory is fine, and so is the CPU but it seems like after a while of inactivity with monitor shuts off the GPU like self hibernates.

Get a good brand power supply no matter what. For a pc with a R7 250 you only need a 380W psu.

It might fix your problem too. download and run hwinfo and post the 3 screens of sensors readings - so we can check your power supply and other.
