Any suggestions as to what happened?

System is as follows:
i5 3550 @ 3.3 Ghz
8GB DDR3 1333
2TB WD Green (not original)
AMD Radeon 7750 1GB
Power supply 600w
Windows 10 home, 64 bit

I finally decided to upgrade my graphics card and got an AMD R7 370, 4 GB. I figured this represents quite an improvement on the old card. While I was at it, I decided to add 8 GB RAM as well. Open the case once and big gains for less than $200 right? Not so much.

I installed the new ram - 2x4 gskill DDR3 1333, to match the existing 8 GB. I installed the video card, but then realized that I did not have two six pin power leads to plug it in. I tried it with one, but the computer would not boot. Turn on, fans come on, turn off. I read some previous posts that suggested the PSU would be the most likely culprit.

Nonetheless, I tried removing the new card and ram and try again....still no boot. Same symptoms.

I upgraded the PSU to a modular corsair RMx 750. Installed the graphics card and the ram again and still no joy. Same symptoms.

Is it possible I fried the motherboard or the cpu? How can I determine which is the problem?

You probably just need to clear the CMOS. Unplug the PSU, remove the CMOS battery, then press the PC power button for a minute or two. Then replace the CMOS battery, plug the PSU back in try booting just using your original two sticks of RAM and old GPU. If it boots, you can then try reinstalling the new graphics card. You could have a problem with RAM compatibility (even though the two sets are the same model) or you need to change settings in the Bios.

Thanks for the quick response...and apparently the right one! It was indeed a memory issue. Despite the fact that they are the same type, there is something that the system apparently did not like. I will just use the new for now and get more of the same brand shortly. Thanks for the assist
