so when I restart my computer it takes more than 10 minutes, sometimes a few hours for my monitor to register that the computer is turning on.

So now you say, check the connection. done, it's fine.

Bad cable? nope, my VGA cable doesn't work either

Overheat? I do not believe so, it does this quite literally EVERY time I restart not just when my computer is at 90 degrees.

at first it took one or two restarts then it worked, then it grew into 5 or so, now its 20-25 times I need to turn my computer off and then back on before it works again.

any ideas?

uhhh no, I don't have another monitor, but I can plug the monitor I have into my laptop and see if it works, if that's a good idea. Will edit with results (dad's emailing some pictures on the desktop right now, can't move the monitor)

EDIT: Ok, monitor runs fine on my laptop, no issues booting into either windows or arch linux (well, except that my xinitrc wasn't read correctly, but I didnt expect it to be)
so now im still really confused

@broni: ermm, it doesn't disconnect upon booting windows, it simply doesn't turn on when I boot the computer, so yes I guess you could say same problem in safe mode.

@caperdog: I honestly have no idea if this is right but in dxdiag, under "System Model" is Dell DXP061

I believe this was stated in OP, my monitor does not recognize the signal from my computer and does not come out of power save. Upon turning the monitor off and back on it says something like Monitor is not recieving signal from the computer please check the cable, or something like that, I don't want to restart my computer to tell you the exact message cause I never know if when I restart it, it may never work again.

Well, it won't be easy to diagnose your problem over the internet.
My guess would be bad power supply, or dying video card.

heh, both could be true, my video card had a period of about 9 months where it was clogged with dust it would break 130C. but my PSU is only 400W, so who knows, probably the vid card.

it would break 130C

That would, most likely, damage it.

Did you try to remove your video card and switch to on-board video?

Keep us posted. That would be the easiest way to establish, if your video card is bad.

uhhhhhh, im not sure if this is bad, but there is no onboard video card.

anyways, my computer crashed randomly while defragging and talking to people on skype, it got about 1.5% through the defrag, the hard drive whirred loudly and it shut off, took 14 restarts to get back on.

Temps:
Core1: 24C
Core2: 27C
GPU: 66C

also, it took a couple of minutes for the desktop to display icons, it sat there showing the background and mouse but nothing else.

EDIT: im gonna run a defrag using MyDefrag (windows defragger hasnt worked for a while) while I go apply for a job, I will let you know if the defrag finishes or if it crashes while I am gone
