this is a frankenstain computer that I've build for my mother that like to play old gdr.
* i3 3220
* mobo: MSI PH61-P33 (B3)
* 2x2gb kingston hyperX
* 1 hdd sata maxtor
* GPU Asus HD 7770
* Vultek PSU 600W (new)
When I power on the pc I have a black screen, no beep, nothing. the pc simply won't boot.
BUT, when I clear the CMOS everything works.
The first strange thing is that the pc won't power smootly. I try to explain better: when I reboot the pc first shutdown power (all fan stop, all led down, like it's power off) then suddendly start, and It's really strange 'cause I've never seen a PC that reboot in this way, in a normal reboot, pc doesn't power off completely.
* So, I first try to play with BIOS, xmp, voltage on ram, ide/ahci, overclock, optimal setting, default setting.
then I bought a new battery.
* I bought a new PSU
* then I take of the CPU and clean a bit of dust that I've found under the socket but didn't help.
* I try to disconnect all addictional fan of the case.
* I try to have only the power button connect and nothing else
* **Then I take off 1 ram, and the pc starts!**
now: I have two slot I try every single combination between ram and slot and I found out that both ram works, BUT if I insert two ram, pc won't start (until i clear cmos), If I insert one ram (eather in slot 1 or 2) the pc starts.
can be the mobo faulty? or I'm forgetting somthing? something I could try to have the two ram slot working? is an hw problem? a bios problem? I really want to give my mother this pc as gift but I don't have money now to buy an old lga 775 mobo.
Thanks all for the advice
and sorry for my bad english
