Remove and reinstall each ram stick.
Make sure their nice and firmly seated......test.
Maybe grab a copy of Memtest.......use goggle.
Let it fly for 10/12 hrs.
Here goes: In the boot screen there is that "Memory dual channel interleaved" and bellow that there are 4 channels where some coding is written next to them or simply the word "None". Now there is the thing some times when i turn on the pc, one or more of these channels have nothing written next to them, they are completely empty fields and then the booting stucks there until i turn off the pc (force restart button doesn't work either when that happens so i have to keep the power button pressed on until the system passes out). The restart usually doesn't fix the problem so once while experimenting i tried to unplug and plug again the wires connecting the motherboard with the other parts, or plug them on different slots. Its a dumb technique i know but it seems to work for some time (god knows why i really can't understand how it works but it does, my friends don't even believe me!!) but unfortunately the incident happens over and over every 2 weeks or so and i have to go through it again. Anyway i'm planing to replace my old Ati 5570 with a GTX 660 which i can barely afford and i don't want to risk burning the card if my system is malfunctioning. Anybody experienced anything similar so far and came up with a solution? If yes please let me know if there are any parts i should replace and have my system working properly again (low cost solutions please i don't want to buy an entirely new pc).
MY pc specs are:
CPU: Intel Core 2 Quad Q8300
Motherboard: GIGABYTE G41MT-D3V
Graphics: Ati Radeon 5570 2 GB
RAM:4.00 GB Dual-Channel DDR3 @ 533MHz (8-8-8-20)
PS: Sorry if my english are not good enough i tried my best.
