|"A Simple "What board are you using Or, is this PC Factory built, etc? Would have been a more general Question to have asked."|
Probably so. But it gets annoying when people come here for help & don't provide the necessary info to get that help...then we have to go thru followup question & after followup question to finally get the info we need.
The CPU support info can be found at the motherboard manufacturer's website. However, there are 5 different PCB versions of that board, so the next question is...which do you have? Version 1.0a, 1.0b, 1.0B Viiv, 3.0 or 3.0 Viiv? I'll go with v3.0:
It doesn't look like your new CPU is supported. What you *should* have gotten was one of the 800MHz FSB Pentium dual cores that are based on the Core 2 Duo, then simply increased the FSB from 800 to 1066MHz. The E2180 for example, overclocked to 2.67GHz, would spank the sh!t out of the D 965 Extreme @ 3.73GHz.
"Yes New heat sink had a pad preapplied. As per the info from another Tech, The preapplied Crap was removed and Actic Silver was re-applied. Thin layer evenly on bottom ov heat sink."
The "Tech" steered you wrong. You should have used the pre-applied pad for the initial installation. But since you decided to remove it & go with paste instead (especially Arctic Silver), it MUST be applied properly. Applying it to the heatsink like you're buttering a piece of toast is NOT how it's done. A small thin line should have been placed down the center of the CPU, in line with the cores (not perdendicular to them), then the heatsink should have been installed. No spreading of the paste is necessary & the amount used should be roughly the size of a grain of rice. If too much is applied, it no longer helps to transfer heat from the CPU to the heatsink, it prevents it. Here's the instructions:
