Possibly a heating issue??

I have built a rig for a friend, he didn't have a huge budget and really wanted a Gigabyte mobo. I put the rig together (specs shown below) and I am having what I suspect is a CPU heating issue. The system appears to be booting fine, I am trying to install windows, and I had a system crash as soon as the CD started to read, I thought that was somewhat odd, and so I tried to fire it up for a second round, this time it didn't even get to the CD reading... it crashed during boot.

At first I suspected a PSU problem (always suspect the PSU when I use a generic) but I exchanged it with another PSU (still generic) and it still didn't work.

I couldn't even get far enough to enter BIOS. I tried booting with no side panels on, and then even resorted to directing a fan onto the rig. I will make a note that the heatsink was particularly hard to get on for this rig... maybe it is not making good contact? Maybe I have a bad CPU? I don't really know what the problem could be... I wouldn't think I would be having heat issues just on boot up.

Thanks in advance guys.

System Specs:
A64 3200
Gigabyte GA-K8N
6800GT
1GB OCZ (matched)
WD 80GB SATA
Generic 400W PSU

IS the supplemental cpu supply voltage line connected to the mb? (Older ATX PS varriants will not have it, the P4 compatible units, atx12v, will have an additional 4 pin connector, and nearly all NF3/4 boards will also require this input to be connected, supplies the cpu with more current. In my Athlons case, it will not eveen POST without it))

Also, did heat sink come with pre-existing grey colored thermal compound? Was strip of tape removed from bottom of heatsink? Is heatsink fan connected to mb, as many mb's might refuse to run without some sort of RPMs registering on this line; must be connected to "cpu fan" on mb)

What would be the sympotoms of a bad cpu?

bad cpus are extremely rare, it is most likely, like 99.9% that the issue lies elsewhere. especially since you were able to boot. try some different memory, clear the cmos, make sure all the power connectors are hooked up and there are no standoffs in places they shouldnt be. how generic were the generic psus? it should be at least 350w for a generic psu to boot this system up, and with a p4 connector too dont forget.

This really sounds like a power issue to me. A device starts consuming more power and suddenly the system crashes?

this sounds like a power issue to me too

here's sommething funnny to try. not replaceing the PSU itself

the power cord

i just had this happen to another fellow on another board. we just replced the cord and eveything worked.

That reminds me of all the times when we had SCSI cables being pinched and the service technicians kept blaming the software for the problems. Sometimes you just have to trace problems back to the source instead of jumping to the easy conclusions. :twisted:

Hi Starfishy.
Any time I've seen people having problems installing a hsf, it's ended up causing problems.
Maybe there was something out of place, or maybe you are just not used to the amount of force required to install the units for the A64.
I know it's a pain, but I suggest you take the mobo back out, and reinstall the hsf.
Dont worry too much about the amount of force required, the heat spreader does a good job of protecting the core. Remember, if it doesn't feel right, it probably isn't.

Isn't that about how Catholics define what is and isn't a sin? :lol:

Not bloody likely. I'm sure that goes something like "If it feels right, it's probably a sin"

:lol:  True. Maybe we're making this too complicated. It's probably more like:

I want to say power supply just because it's generic but during post and setup nothing is consuming enough power to put a load on it. The GT wouldn't even start to ramp up not in 3D mode and the other components don't draw near enough to tax it.

Perhaps try a single RAM module at a time? Maybe it's the SATA cable, I'm assuming you're using a cable that came with the mobo and those are usually crap!

Although, I did work on an old P3 system that wouldn't post because the power supply was bad. The CPU fan wouldn't come on, switched in a new power supply and it worked.
