freezing help, overheated cpu?

[chooch709]

The PC is my familys pc, its something along the lines of an amd xp 2600 w/512 stick of ddr and a geforce3. I built it using parts that I had around and a few new ones probably almost a year ago now.

So the problem: Turn computer on, it'll get to desktop. Let it sit for ~20 minutes and it'll lock up and you get horizontal lines across the screen. If you reboot it, it either won't turn on at all (which suggests overheating and the motherboard protecting you from turning it on while its too hot) or it gets to like the windows loading screen before it locks up and the screen gets a bunch of horizontal lines on it again.

My first assumption was that the video card was shot, so I replaced it with my sisters and that didn't do it. Then maybe I thought it was bad memory, so I tried that without any success. I don't have any other identical motherboards to make any kind of swap to see if its the proccessor or motherboard specifically, but thats really the only other thing to check. Its obviously not the hard drive, and I've checked the other major components.

Assuming that the proccessor fan is 100% void of dust and the case is sufficiently cooled, can anyone think of stuff to try before completely replacing the motherboard and processor? That would really be a PITA :/ Going to post this to a couple forums I visit to see if I can get any good suggestions, thanks for any possible help =)

Are you sure the CPU fan is spinning?

see if there are any puffy or leaking capacitors on the motherboard.

I'll check for capacitors, other people I've recently asked the same question to keep coming back saying to check the motherboard.

The pc is basically dust free, but I'll definitely double check it.

Thanks for the suggestions

Other than making sure that the fans are spinning, the heatsink is seated correctly, and the voltage is set right, you could try maybe underclocking and/or undervolting the system so that it doesn't get as hot. And there's always the old test of take off the side panel and aim a big house fan at the open case.

There is a program called MBM5. If you run that, set to keep a log, it will tell you what your voltages, and temps are.

If you get MBM5, then make sure you enter the correct mobo or you may get inaccurate readings.

At least assuming that you have the requisite sensors. I'm still miffed that Dell PC at work doesn't. 🙁

You'd think that with the underclock (for stability and quiet) that likely goes into a lot of Dells that you wouldn't run into too many heat problems...

I'm more concerned about voltages than heat. I just figured out that if I unplug my USB smartcard reader from ACS (and god only knows how <i>little</i> power it consumes) my system gets way more stable. (And I know it's not a software problem because my old PC had that thing plugged in while running 24/7 for months in a row without a single need to reboot and without any problems.)

Gotta love the minimalist PSU stance. Squeezing every bit of savings out of each sell they make. Try to upgrade later and then run into stability problems because of a lack of power.

What changes have you made to increase the W draw?

Yeah. 🙁 This is <i>exactly</i> why I personally don't buy from major OEMs.

I added one stick of RAM and plugged in one USB device (the ACS smartcard reader). I'm just sucking up the watts with those upgrades. :O

ROFL! How can you be so brutal to your nice little Dellie? Shame on you.

<sarcasm><i>Ja. I know. I am evil to my boxen. My one extra stick of RAM and very low power usage USB device are like hungry beasts bent upon devouring all of my PSU's power.</i></sarcasm>

Seriously though, what also bugs me about this box (besides the PSU being right on the edge and the mobo having no sensors, and just being a Hell) is that it's got an 845 mobo that has absolutely no overclocking capabilities. So even though it has a NWB set to 533MHz FSB, I can't even so much as overclock my PC1600 RAM to synch. 🙁 Ugh. Stupid machine. Had I any say whatsoever in its specs, it would be a very different PC.

Still, considering all of the other Hell boxes I've seen around the office, I'm actually quite lucky that these are my only problems. :O

Dell is most definately the new 'Crooked <i>E</i>'.

All that being said - there are still people who should only be allowed to have a Dell or other major OEM. There aren't enough people like us in the families across the nation to take care of all the family PCs. That tech support "blanket" is critical to them maintaining sanity.
The better option is a good local PC shop, but not every city/town has a good one and the cities with good ones still don't have 24hr tech support. As much as I don't like them and some of the products that they put out, they do serve a purpose.
