First PC Build, CPU Overheating, Heatsink advice needed!

Hey guys, I just completed my first PC build yesterday. Everything went smoothly save for the installation of a Scythe Ninja Heatsink for my E6750. I followed instructions to the T, including those posted on Arctic Silver's website for the application of AS5 onto a Core 2 Chip. (A thin vertical line over the center while directly facing the proc, yellow arrow in the bottom left. )

My initial boot was succesful, all my bios options were set up perfectly, but when I went to install my Vista it hung at 97%. I knew from previous installs that vista can have long periods of waiting, so I let it sit for 20 minutes. Nothing. I restarted, and again it froze, only this time before I even had a chance to select which partition to install to...I'd call it maybe 3 minutes before stopping. Another reboot to check the BIOS settings...and what a surprise, it froze again, only much faster, in the area of 45 seconds. At this point I shut down the system and did a bit of research. I concluded from two facts, the repetitive freezing and the fact that the heatsink had not installed "easily", that the cpu was overheating.

Now, I stopped working after discovering this (it was 9pm and I had to study for an exam) but I do need some advice on several fronts:

1: If I attempt to re-seat the Scythe HS, should I still follow the Arctic Silver instructions for application? Should I attempt the "credit card" method and thinly coat the entire surface instead? Do you have any specific advice for cleaning and preparing the processor for a new application of AS5?

2: If the Scythe continues to give problems, will the stock HS provided by intel be sufficient for any overclocking? What other heatsinks would you reccomend?

My system specs:
Antec P180
Asus P5N-E SLI
Intel E6750 C2D
2GB (2 x 1024MB) Corsair DDR2 6400 (800Mhz) Cas 5

Thanks in advance.
 
Hmm I would be more worried that I cooked the CPU. There are several different heatsinks that will work. As far as the overclock comment I am not sure, I seem to find mixed reviews on the stock heatsinks!!
 
The CPU prob saved itself. I would do a poor mans check on the flatness of the CPU and the heatsink. Use a credit cards edge to check the flatness. If it looks flat clean everything off and reinstall it.
 
You cannot damage a C2D or quad with temp, it will just thermal trip, cool off and be good to go. You can damage the internal transistors with too much Vcore regardless of how well you cool it.
 
I've just put new rig together with the same HSF (see my sig) and I didn't experiance any problems. I did lap the HSF a bit and I've used the 'credit card' method to apply AS5. Also I'm always using 99% Isopropyl alcohol to clean cpu/hs before applying thermal tape.

Did you install the fan properly? is it blowing air in the right direction? Also make sure pegs are properly sitted on your mobo. I did install my HSF with the mobo outside of the case, so it was easier and I was able to see that they were sitted properly. The socket 775 mounting mechanism that comes with Ninja is not the best and some people were actually buying seperate 775 mounting kits for it. Myself I haven't had any problems with it.
 
Okay, new problem. I've got the stock hs and fan installed (i'm returning the scythe), but now I'm face with the dreaded "i refuse to boot for you" issue. What makes this slightly more difficult is that the motherboard doesn't have any post lights or a speaker, so god know what the hell is wrong with it now. I already tried clearing cmos, to no avail.
 
pretty sure all mobos have beep
you no get a beep?
i think no beep == something wrong with mobo or cpu, including, but not limited to, cpu seated incorrectly
disconnect everything except power from PSU, CPU, 1 stick of ram (preferably a known good one), and CPU fan....*edit* keyboard...hehe
don't need HDD to get as far as BIOS
if PSU fan kicks on? does CPU fan kick on?
 
psu connected, video card connected, one stick of ram, still unresponsive. It literally just sits there, on, but not displaying anything on the monitor. The video cards and the cable work fine on my old computer. i'm thinking its a motherboard issue, since everything else seems to be working.

this includes the psu fan and led, the gpu fan, the cpu fan, and everything else. It all runs, but it doesnt know what to do with itself.
 
Might be a short. Try running everything outside of the case. Also double check the 12V connector and RAM seating, make sure they're pushed all the way in. Either one of those are easy to seat/connect improperly and would cause the symptoms you're seeing.
 
but, now we have a little more to work on. however, no beep isn't good. i tried looking at your mobo's manual, but it doesn't have a troubleshooting section, wth? i guess we're suppose to assume it uses default (but, not really, just widely used) beeps?
deep cmos reset => switch cmos jumper to reset position and leave it there, remove the cmos battery, unplug the PSU from the source, wait 1/2 hour, reverse operation, try to boot
 
as i mentioned before, there is no speaker on the motherboard. there is also no case speaker. which leaves me high and dry


everything is running "fine" outside of the case, in that it's all working, just not together to bring me into the bios


i may have an old post card, let me check in my basement
 
Definitely a motherboard issue. Three separate video cards worked in my old system and not on this. The cpu worked in my brother's system. The memory is still good. Yeesh. Talk about frustrating.
