"Hey, I've had quite a frustrating few days. Over a week ago I put together a new system. (Components listed below) Worked wonderfully for 5 days or so, until I get home from work Wednesday and when I powered it on it would start to boot up for 2-3 seconds and then shut down, another 2-3 seconds later it'd power itself back on again, shut down.. you get the idea.
Anyways, I did some research and asked questions on the net and was told it was probably a PSU or mobo problem. Luckily, I had a new PSU coming the next day, that did not fix the problem. So I talked to Newegg and had them overnight me a new motherboard for a replacement. Got that on Friday, and still the same problem.
I have a friend with very similar components, so we swapped parts back and forth trying to find out what was faulty. Nothing of his would work on my board, including the CPU and fan, PSU, Videocard, and RAM. However, my videocard and CPU worked in his system. Leading me to believe that they are OK. We found that one of my two ram sticks would cause his system to show the reboot symptoms, but the other one worked fine.
So it looks like I'm sitting on two bad motherboards and 1 bad RAM stick. Has anyone seen anything like this before? Is it possible this RAM went bad a some point and then fried both boards I tried it in (yet left my buddy's board intact?)
Gigabyte GA-P35-DS3L
Core 2 Duo 6750
CORSAIR TWIN2X2048-6400
SAPPHIRE X1950PRO"
I've done a little more research and found that the RAM I have is listed at 1.9v while I guess the default for these boards is 1.8v. Could this be my problem? And if so, how come I was able to run great for almost a week on my first mobo before experiencing this problem and then not being able to run at all with my 2nd replacement (even with the known good stick of RAM).
Thanks!
