I thought I had cleared the CMOS but reading some of the posts on pressF1 i realized that theres more to it than just changing the jumper. So CMOS is a possibility i guess. What do you mean it beeped for lack of power?? You can't start it without the PSU connected, and a 350W PSU should be adequate for the specs. There isn't a lack of power beep. As for clearing the CMOS, the jumper on the MB is the way to do it. You can select Reset To Default from within the BIOS also but the jumper does the same thing.	pctek (84)

The new heatsink is arriving wednesday so expect a post either (nz time -late thurs night probably) that is if youre following this post. Its extremely important to buy a hsf/fan that is specific to your CPU. For instance if it says Socket 775 and you have a Socket 939 CPU then that would be no good. And research them carefully if using something other than the stock one that normally comes with the CPU. They are not all equal - some have better cooling than others, not to mention how hard/easy they are to install. For instance I have a Thermalright XP90 which involves removing the back plate and retaining frame from the MB and installing the custom Thermalright one. I wouldn't recommend it to someone without any experience.... If as seems to be the suspicion - you didn't have the old heatsink on properly and ran that CPU for any length of time - it may have killed the CPU now.	pctek (84)

There was a huge gap of air between the cpu and no way any heatsink cooling compund would bridge that (you shouldn't use that much anyway). One of the push pins wasn't properly inserted (although visually this was hard to see) and so the bottom of the heatsink wasn't flush with the top of the cpu. Damn tricky design. Assemble on an anti-static surface and you can have a good look to confirm the heatsink is properly attached. Follow instructions on heatsink installation carefully. The manufacturer of your heatsink may have better instructions with phots on their website.	gibler (49)
316162	2006-01-10 22:37:00	Did you (a) put thermal grease between the heatsink and the CPU, (b) use too much/too little grease. (c) put the heatsink on the right way round? See here (www.pressf1.co.nz) for a cautionary tale. :blush:	Tony (4941)
