Hello all,
I'm having a bit of an issue if anyone would be able to help.
I had a advent dt1411 prebuilt which I recently decided to upgrade with a new graphics card and psu.
It has an intel i5 2320 processor, HD6670 gpu, no brand 405w psu and a Foxconn, H61MXL/H61MXL-K mobo.
I went for http:// and http://
After uninstalling my drivers and attaching the new psu & card, the system starts, beeps and then restarts (all while with a black screen). And then all fans and stuff are working but nothing else happens. I get no signal.
When I switch my new card back to the old one, it all works fine.
This is my first attempt at upgrading my computer so I have no idea what has gone wrong.
Any help would be appreciated.
Also I have plugged the two 6 pin connectors into the new graphics card and plugged all the other things in same as it was with the old psu.

Thanks,

Does the old card work with the new PSU installed? If yes that proves the new PSU is ok.
Do you get the same number of beeps with no graphics card installed? Are you sure that new card is inserted correctly? Are you able to test the new graphics card in another PC?

Old card works with the new psu. Without a graphics card it turns on normally but with no signal, no beeps. No , I have no spare PC to test.
