So I am building a budget pc for my brother and I decided to buy a preuilt system and upgrade it so I bought him a new gpu tested it and everything went perfectly the pc I bought only had 2gb ddr2 ram so I decided to buy 8gb ddr2 and after upgrading the ram the monitor would not show up as well as the led from the pc which would only appear from time to time I have then tried the old ram and I get the same issue i have also tried a new psu, new mobo tested the gpu on my pc it works also when I have the new ram in I get no beeps but when I have the old in I get 2 beeps

List ALL your hardware.
Reset the BIOS

 

[lolek1234com]

8gb of ddr2
Intel Pentium dual
GTX 710
And a preuilt Fujitsu Siemens pc mobo
80gb HDD as my brother will not need more
And I have already reset the bios

 

[dudio]

Still pretty vague.
What motherboard specifically?
You also need a power supply, or it won't run. Do you have a PSU?

 

[lolek1234com]

Yes I have a psu and yes I have tried a different one

The mobo is a Fujitsu Siemens Esprimo p2511 mobo

Maximum supported RAM for that motherboard is 4 GB

Still doesn't explain why you can't boot with the old ram.
Try 4 gigs, and reset the BIOS again

I can't seem to only use on stick of 4gb

 

[lolek1234com]

And also I managed to boot with the old ram

 

[dudio]

I can't seem to only use on stick of 4gb

Yes.
Not sure which slot to use, as it's hard to find much info on that motherboard.
