A while ago I rebuilt my brothers computer and upgraded it with a new video card
Specs:
q6600 @ stock 2.4
Memory: G.Skill 4gigs ddr2 800
Motherboard: ga-ep35-ds3l
Video: EVGA gtx470
PSU: Corsair 750w
HDD: Seagate 250gb
It originally had a 610w psu and an 8800 gts 512
When i first rebuilt it, I added the gtx 470 w/ the 610w psu and started noticing a random black screen (no signal to monitor)
as well as the computer freezing at times
Since then I have upgraded the psu to the 750, tested the memory, tested w/ different ddr2 800 memory wiped the computer, driver sweeper/reinstalation of drivers upgraded the bios and a whole lot of other things that i dont remember.
The new PSU is working perfectly and to the correct voltage, both sets of memory work fine in a different computer
The 470 also works fine in another computer, and has been RMAed just in case. and the new one has been tested with the same problem.
With the above specs, the computer works perfectly with its old 8800gts 512. It freezes only with the 470 in.
With the 470 in, the computer freezes in safe mode, in the bios and just about anywhere possible.
Im thinking its the motherboard, but it could also be the processor as well could it not? I was also told that its possible for the memory to not be compatible? I never even thought that was possible but thats why im asking.
memory voltages are also fine, processor voltages etc, everything is set to auto or manufacturers specified. I have disconnected anything unnecessary from the computer and have used it with different keyboards monitors etc
It simply freezes w/e the 470 is in and the only things i have not changed so far is the motherboard processor and have not tried faster memory.
What are the odds though that it could be the processor or memory? Im thinking of just scrapping the motherboard processor and memory and just buying him the new i7.
What on the motherboard could be broken that does not let it work with the 470? thats what im trying to figure out before i start spending more money on another solution
Any advice is greatly appreciated.
