P5Q Hangs when installed E7300 is my CPU dead

February 13, 2011 at 23:14:19
Specs: Windows 7
I have a P5Q ASUS Mobo with a E7300 core duo 2 CPU in it running well for yrs on Auto Bios settings NO OC. I needed to test a Intel® Pentium® D Processor 930 on my P5Q which ended up working find. When I try to put back in my E7300 CPU it now starts up for 5sec than shuts down then Restarts it self with no beeps, no post or bios and hangs with all fans running. I have the latest Bios Flash installed. The Pentium® D 930 seems to be the only way I'm able to start up my p5q to even Manually change Voltage settings to C if my E7300 will even start back up, i have cleared CMOS many times and tried many small changes to the bios. Though the out come is always the same starts up for 5sec than restarts and hangs. did the CPU get fried? any ideas?

Sounds like an improper heatsink installation.

The thermal paste application for the Core 2 Duo is different than for the Pentium D. You should be using the "vertical line" method. Here's the instructions:

I have put the heatsink so many ways small line form, covered, 3 little lines same out come in each case it starts up for 5sec shuts off than restarts and hangs. Doesn't even beep when i have the Ram out. But once i put back in the Pentium® D it has no problem running my comp. Not sure how it happened but it is totally acting like the cpu is fried or not functioning properly =(

"I have put the heatsink so many ways....."

There is only one correct way to do it & that way is described in the link in response # 3.

I don't know how you went about removing the CPU the 1st time around, but it's beginning to sound like you fried it.
