Hello and welcome to JustAnswer, I look forward to assisting you today. Is there anything on the screen when you try to boot?

Customer: replied 11 months ago.
nope blank screen when it boots
Customer: replied 11 months ago.

Expert:  Dan replied 11 months ago.

running 2 video cards in sli gtx 580s sli is disabled at the moment
Expert:  Dan replied 11 months ago.

Home built I take it? Do you see even a blinking cursor on the monitor when you boot?

Customer: replied 11 months ago.
nope
Expert:  Dan replied 11 months ago.

This might sound silly, but do you have another monitor you can connect to rule that out?

Customer: replied 11 months ago.
I do that would be a major pain in the neck to change out
Customer: replied 11 months ago.
Sometimes the board will boot but maybe aft
er 50 tries
Expert:  Dan replied 11 months ago.

I understand. Even if you had a major failure of the computer, you should still see the POST screen or at the very least a blinking cursor. Do you have dual monitors connected?

Customer: replied 11 months ago.
nope one large screen 27 inch
Expert:  Dan replied 11 months ago.

Then I would start with the peripherals inside the computer. Any one of the boards connected to the motherboard can be causing this problem. The only way to resolve it is through the process of elimination. Start by removing one of the video cards then restart the computer. If no difference, swap the cards and try again. Do the same with the RAM and any other card you might have installed.

Customer: replied 11 months ago.
alright I tried that beforehand with the video cards
Expert:  Dan replied 11 months ago.

You might even have a bad power supply. Try unplugging it for 30 minutes or so and then try starting it up to see what happens.

Customer: replied 11 months ago.
no luck with the video cards
Customer: replied 11 months ago.
i have no other psu to replace that one with
Expert:  Dan replied 11 months ago.

How about the RAM?

Customer: replied 11 months ago.
no difference
Customer: replied 11 months ago.
on ram
Customer: replied 11 months ago.
I will swap the ram though
Expert:  Dan replied 11 months ago.

Okay. Well I can't tell you for sure what is causing this. I have experienced this myself and the last thing I tried was the power supply which corrected the problem.

Customer: replied 11 months ago.
no on the ram after the swap
Customer: replied 11 months ago.
what about the 1 in 50 times boot
Expert:  Dan replied 11 months ago.

Okay. I think we have tried everything there is to try except swapping the monitor and the power supply. Did you leave it unplugged then try starting it up?

Customer: replied 11 months ago.
no
Expert:  Dan replied 11 months ago.

Okay, do that. Leave it unplugged for awhile then try it again. How old is the computer?

Customer: replied 11 months ago.
built it in 2012
Expert:  Dan replied 11 months ago.

Okay. Try unplugging it for awhile then and let me know what happens.

Customer: replied 11 months ago.
I did for a 30 minute period'
Expert:  Dan replied 11 months ago.

I thought you hadn't tried that yet?

Customer: replied 11 months ago.
I did
Customer: replied 11 months ago.
I can repeat it
Expert:  Dan replied 11 months ago.

You could. I want to make sure it is cooled down well enough before you restart.

Customer: replied 11 months ago.
ok
Expert:  Dan replied 11 months ago.

If that doesn't work, you don't have many options left.

Customer: replied 11 months ago.
i know
Expert:  Dan replied 11 months ago.

Look closely at the motherboard at the tops of the capacitors. They should all be flat on top.

Customer: replied 11 months ago.
The intermittent boot issue went away about 80 boots ago
Expert:  Dan replied 11 months ago.

Have you checked the board yet?

Customer: replied 11 months ago.
no change
Expert:  Dan replied 11 months ago.

You checked all the capacitors?

Customer: replied 11 months ago.
all flat on top
Expert:  Dan replied 11 months ago.

Okay. Well just leave it unplugged for awhile then see what happens and let me know.

Customer: replied 11 months ago.
okay
Customer: replied 11 months ago.
I tried another screen same difference
Customer: replied 11 months ago.
I am ready to try another PSU at this point from another tower that works
Expert:  Dan replied 11 months ago.

Let me know the results.

Expert:  Dan replied 11 months ago.

Just thought I would check to see how you came out. Let me know if I can be of further assistance.

Customer: replied 11 months ago.
Tried a new PSU with no luck.
Expert:  Dan replied 11 months ago.

The only thing left that I can think of then is the motherboard. There may be a jumper on the board to clear the CMOS. If not, pull the battery and let it set for several minutes to see if that will clear it. If that doesn't work, I am out of ideas. Let me know.
