We simply return it, using the warranty to get a new one that works. Why try to fix something that's supposed to work right out of the box?
Hope this helps.

I bought a new pc in working condition and tried it in its original case, first time it wasn't showing anything on display, but on second boot it started and everything was working fine. Than I put it in new pc case and same problem occured. Pc fans are spining but no picture on display.
The same thing used to happen to my old pc, but I solved problem by pulling of RAM and putting it back.
I tried everything: restarting bios, cmos, RAM, changing power supply from old pc, swapping HDD, only thing I couldn't try is graphics because both of them have integrated cards.
Please help
