Help, PC Won't Post

[sbarrier]

My wife was not happy with the noise that my new PC made (please see sig for specs). The most noise was being made by my CPU Heatsink/fan (Coolermaster HHC-001). The fan was running about 7600 rpm.

I posted in one of these forums about a quiter solution and a recommendation was made to replace the fan with an Enermax 80mm and an adapter. I ordered both from Newegg and installed them once they arrived. I turned the PC on and fired up 3D 2001 and MBM 5 to test the new cooling solution. Well the PC ran for about 2 minutes and then cut off. It will not come back on properly now.

All I get now is a 1 second beep about every 4 or 5 seconds and it will not post. I've removed all of the cards and unplugged both IDE channels and the floppy channel. I've removed and reset the memory. I've even tried a new stick of memory that I just received. All to no avail. I even tried re-mounting the older fan and I keep getting the same results.

I've done some research about the beeps and it sounds like it is either the memory (I don't think that it is the memory because the brand new memory doesn't work either) or the CPU. All of the fans will come on, so I don't know if the MB is fried or not (if it is fried will it continue to power the fans?). Does this point to the CPU?

With my HHC-001 I was getting 38 - 47 C as the temps, so my new cooling solution would have had to have been much hotter to be a problem.

I purchased all of the items from Newegg and I even bought the 1 year extended warranty for the CPU (it is an OEM CPU). Can I RMA the items with them? Of course I'm not sure which items to RMA. What kind of experience has anyone had with their customer service?

Thanks,

Shon

If your motherboard powers up it definitely can still be defective.
Sounds like a memory or video problem though, make sure you firmly
install both to be sure they are locked in and making good contact.
Also be sure you have your CPU fan plugged in to the correct header
since some motherboards will not function properly if it is not.
Last but not least try clearing the CMOS if the above does not fix
your prob.

If I read your message right, you put a new fan with an adapter on the CPU cooler. Did this adapter plug to a PS connector? If so, then there is nothing plugged into your MB CPU fan connector. Lots of MBs won't work without something plugged into this connector. And if the adaptor is for plugging into the MB CPU fan connector, check to make sure you didn't reverse the leads on the adaptor.

You can try putting the old fan back on the cooler and clearing your CMOS to get rid of the no-fan condition. If that works then you might have to find another fan solution for your cooler. Just make sure you get a fan with a 3-pin sense connector so it will work plugged into the MB connector.

Good luck.

Yes, but if it was a "no fan connected to the MB header" problem, would it have run for several minutes before shutting off?

Sbarrier -- when you put the new fan on, did you take the HSF off the cpu? And, if you did, did you clean off the old thermal interface material and apply new? Did you encounter any difficulty putting the HSF back on?

I'm hoping you didn't burn out the CPU due to overheating, or crack the core reassembling the HSF... Visually inspect the CPU core for signs of damage...

Have you got another CPU you can try in the motherboard, or another motherboard you can try the CPU in?

Good luck!
