|A few weeks ago, i rebooted my computer and the monitor failed to turn on with the reboot. I manually turned the pc off and back on again, and the monitor powered up normally. Since then it has progressively gotten worse... every time i reboot/power off the pc, i have to turn the pc off and back on 5-10 times before the monitor will come on. After troubleshooting, I feel like this is more of a PC problem than a video card/monitor problem... but not sure what it is.|
Here is more detail of whats going on:
The problem: Power off the computer... both the PC and monitor turn off, and the monitor light turns from green to amber. Press power on the PC - the keyboard lights immediately (and briefly) flash green and the PC fans/drives start running, but the monitor stays off with an amber light. Eventually, after 5-10 power cycles, the monitor will turn on and give a green light... when this happens, the keyboard lights flash green a 2nd time at the same time the monitor turns on.
I have tried using another monitor, and the same problem happens.
I am using the integrated graphics vga port... i tried installing a video card, and the same problem happened.
I disconnected all CD/HD drives, and the same problem happens.
I removed all ram -- leaving only the monitor and keyboard/mouse connected. I powered up the PC to see what happens... only every 5-10 power cycles would i receive the BIOS beep indicating (im guessing) a ram problem (1 short, 1 long repeating). Every other time, the motherboard fans would just power up and run without any beeping.
Even though the hard drive powers up, it doesn't appear to do anything past the initial power up when the monitor fails to activate. Only when the monitor turns on do i hear the hard drive load the OS. Each time i power the system up, and the monitor doesn't come on, i do not hear any hard drive activity during the time it would normally be loading the OS.
I'm not sure if this is related, but i also recently developed an intermittent problem where my screen suddenly displays nothing but unchanging digital garbage... when this happens, my entire pc locks up and i am unable to do anything except manually power off the system.
Seeing that when i remove all the ram, i only get the system error beeps at the same frequency that the monitor activates when everything is connected, it tells me that it probably isnt the ram, monitor, or hard drives. So what does that leave? PSU and motherboard? Any ideas?

Thanks for any help!
