pc wont boot up

[TyTron18]

i tested all of the ram and each time i started the pc up it beeped 3 times

[phillpower2]

So you got the same three beeps when you tested one stick of RAM at a time in each one of the slots.

Were the beeps long or short.

[TyTron18]

there like 1 second beeps

[phillpower2]

So you got the same three beeps when you tested one stick of RAM at a time in each one of the slots.

You missed answering this which is important to know.

In addition to the above, do you get any error beeps if you power up with no RAM in any of the slots.

[TyTron18]

yes i got the same three beeps after testing each stick of RAM,and there was no error beep with no RAM in any of the slots.

[TyTron18]

im sorry the same 3 beeps are there when there was no RAM

[phillpower2]

The no beeps with no RAM in the board is odd :unsure:

Does your MB have two black and two blue memory slots.

[phillpower2]

Oops missed your double post

[TyTron18]

My MB does have 2 black and 2 blue slots.

[phillpower2]

Try two sticks at a time in the two black slots and swap them around until each stick has been tried with the other three sticks in both of the black slots, if no change, repeat the process with the RAM being inserted into just the two blue slots.

I know that the above is long winded but without having a known good PSU, RAM and working GPU to swap in we can`t do anything else, an explanation as to how this test normally works below;

it is a custom build, the cpu is an intel i5 2500,i have 8gb of ddr3 ram, i have a geforce gtx 560 ti 1gb, and 600 watt power supply

after a few times it wont boot up anymore, the pc turns on and the fans are blowing but my keyboard, mouse, or no display will come on.

When a computer that has your type of specs behaves in the way that you describe in your OP the first suspect is the power supply as that is what is supposed to provide the power to your MB and any hardware that is connected to it, this includes the DIMM slots for the memory, the USB ports for the keyboard[COLOR=rgb(226, 80, 65)] **, mouse and the GPU.

3 beeps with or without RAM in the MB suggests a memory problem, not with all of the RAM itself but with the memory slots on the MB, this could be down to the board not getting enough power to the memory slots or the chipset on the MB being bad.

Swapping in a known good PSU needs to be done before you can do anything else I`m afraid.

[COLOR=rgb(226, 80, 65)]** One major downside to having a MB that does not have PS/2 type ports for a wired keyboard is that should the USB ports not be working for some reason the computer will fail the POST (power on self test) as no keyboard will be detected by the BIOS, an undetected keyboard can also result in three error beeps.[/COLOR][/COLOR]

I went and got a new PSU (EVGA 600 watts) and the same 3 beeps happen when i turn it on

Before trying the replacement PSU did you;

Try the additional RAM testing steps post in my reply #25.

Read the “how this test normally works” info.

[COLOR=rgb(44, 130, 201)]After you fitted the replacement PSU;

Was there any change with any other hardware, keyboard or hard drive activity LEDs lighting up etc.

Did you repeat the RAM testing steps.

Couple of additional questions;

Does your keyboard use batteries, if yes, try replacing them with known good ones.

Have you tried swapping the USB port that the keyboard is connected to, try another keyboard if you can, as explained 3 beeps can be caused by a keyboard error.

Now that you have a known good PSU it would be safe to try another GPU if you can borrow one.

[COLOR=rgb(44, 130, 201)]NB: It is not common but not unheard of either for fours sticks of RAM to go bad at the same time but when it does happen it is normally caused by a power surge or overclocking that has gone wrong.[/COLOR][/COLOR]

Any update TyTron18?
