[SOLVED] System won't start up properly ?

[akkers]

I had an issue where the psu had died. After advice on this forum I replaced the psu and everything seems to start up. However, there is no beep and no video display. All the fans are spinning and lights are on.

I took out the graphics card and connected monitor to onboard VGA socket but no luck.

I am not sure what is causing the pc to not startup. I do admit that during the psu replacement I had to take off the massive heatsink/fan to get one of the power cables plugged in. I then reseated the heatsink with new paste.

Have you tried reseating the RAM stick/s too? Was PSU turned off and unplugged when you connected it to the system?

Check and confirm ram and gpu

i7 2600k. 2x8gb Corsair DDR3. Antec VP600P+ PSU.
Everything was switched off when PSU was installed. Ram has been pushed in.

Just one thought. The 12v ATX plug came in 2 halves (2x4 pin), I wasnt sure which side goes left or right but I installed them with the lugs on the front side. If this is wrong could this be the culprit. Does it matter which side the 2x4 pin plugs go?

You must plug in both. It wont be wrong connection, because it has safety feature. No worries. If it can fully plugged into the connector it should be ok.

...but does it matter if one goes right or left and same with other?

 

[Sam4malaysia]

Nope...I told you.

BINGO! SOLVED.
The mobo P8Z68-V - I looked up online manual and it said it had a few diagnostic LEDs scattered across the board which indicate area or problem. So I plugged it in , started pc and I could see the red LED for DRAM was lit up.
I had previously checked memory sticks. Anyway I removed stick A and started pc and still same problem. Removed B and installed A and bingo, no red light and system started up.
So t looks like DRAM stick B is faulty. Anyway I up and running with just one 8Gb DRAM.

Thanks for your help guys.

Did you try both sticks (one at a time) in the working slot?

I do admit that during the psu replacement I had to take off the massive heatsink/fan to get one of the power cables plugged in. I then reseated the heatsink with new paste.

Was the heatsik/fan you took off and replaced applying themral paste the CPU cooler?
