Sandy Bridge system won't BOOT (GA-Z68X-UDH3-B3)

post #1 of 5
Thread Starter 
My heatsink was getting really hot so I decided to buy an after market cooler. I got home, installed it, now the computer starrts, then goes right out.. Starts up, goes right back out.. Then it repeats this forever. If I set the voltage to manual on my power supply, I can turn it on and it'll stay on, but nothing else will ever happen. I'm sure I didn't damage the board by accident, it was a very simple installation.

Another thing I notice are 4 lights that come on and stay on, they're red, yellow, yeloow green, and green. They used to flash when I'd turn my computer on, now they're just sitting there like they're dead. Help? Any suggestions?

If I mess with the switch in the back of my power system, I can get the system to come on and stay on but nothing ever happens, no boot.

Anyone have any suggestions?

First clear the CMOS. If this doesn't fix it (which it probably will not fix it), carefully remove the heatsink. Now reseat the processor in the socket, and remount the cooler and that will most likely fix it. Since this problem occurred when you installed a new heatsink, the issue most likely lies near the CPU socket area and a reseat should fix it for you.

Any chance you forgot to tear the protective sticker on the new heatsink off??

you probably killed the board or CPU through static shock when you installed the new heatsink.
