Hardware overheat? Or not?

By linuxman3 ·
I just built myself a new system. 120gb hd, intel p4 533mhz FSB, 2 x 256DDR memory. I first noticed the problem when i was trying to install xp pro, and it just rebooted mid install. So i ran microscope diag. on it and it rebooted about 15 minutes after that. I
have just been sitting here looking at the hardware monitor on my bios, it shows a steady 35C/95F for case temp, and it shows a 46/48/49C - 116/118/120F as times goes on for the cpu temp. I am sure that an overheat is not the problem. Intel should be able to handle much... much... more heat than that. And true to form after about 15 minutes it shut off again. I just rebooted and it was fine for about 5 minutes. Than it died. Its almost as if it's afraid of my cpu temp hitting 122F. There is no weird smell. I am close to just turning the hardware monitor off. I am sure theres a way. Anyways. Here are the specs:

Power Supply= 400W
MotherBoard = PC Chips model:m963g::sis 661fx/964L
CMOS = v02.54 American Megatrends
HD = Samsung 120 GB
CPU = Intel Pentium 4 2.80A GHz 1MB L2-Cache, 533MHz FSB, PGA-478Pkg.
Version: C61899-004 1.4V Max

Anyone got any ideas... Lay it on me. I'm about ready to RMA the whole load.

It could still be CPU overheating. The temp readout you get might not be the actual temperature, it depends where the temp sensing chip is seated and if it gets firm contact with the CPU Surface. Did you use heat transfer compound between your CPU and the heatsink?

might be the BIOS automatic shutdown temp is set to low. Could be a lot of different things. Faulty power supply, faulty memory, etc. Since you built this yourself. I suggest you strip it down and start over from square 1. take the HSF off, processor out, memory modules out, any PCI cards out including the graphics card if your using one. Reseat the processor. Reinstall the HSF with termal compound. Install only 1 memory module and the graphics card. boot up into the BIOS and reset the BIOS to factory defaults. Check the voltage readouts in the BIOS. Check op temp. Let it run to see if it turns off. if it does, take the memory module out and put the other one in. reboot and see if it turns off. if it doesn't then you've isolated a bad memory module. If could be that the memory modules or cards just need to be reseated.

Troubleshooting hardware is a process of elimination to find the whats at fault.

well i ran memtest 86 on it... sure enough both of my memory sticks are fried. 2 more questions for you though...

a. Can bad sticks cause the computer to reboot?
b. How do i no its only the sticks. Not just the motherboard?

sorry, brain was a little fried on the last comment. What i ment to ask was how do i know that only the memory sticks are bad. How do i know its not also the motherboard slots?

sure bad memory can cause a computer to reboot BUT!!! most of the time that is AFTER the O/S is installed. usually without an O/S you won't boot up but get a system halt. I wouldn't chuck those memory modules yet. Memtest 86, though a good test may show read/write errors but that doesn't necessarily mean the sticks are bad. A crappy power supply can cause problems with memory, the CPU, and all other sorts of problems. a faulty motherboard or incorrectly configured BIOS can cause problems. Your BIOS might need an upgrade. BIOSs do have bugs.

last but not least....why a PC Chips motherboard? price? Asus,MSI, Gigabyte boards are all very good, high quality boards at very reasonable prices.

one way to test computer equipment is to swap out with known good ones. If there is any question at all on the mainboard, return it. Same holds true with sound cards, video cards, etc. There just aren't any low cost test equipment for benchtesting those items. there are test equipment for testing a power suppy [check Antec 's site. they have units for that]. but then, unless you build a lot of systems or need to test a lot of power supplies, its really not worth getting.

The power supply is not bad, I used to work in a computer repair shop and i happen to have a power supply tester. The OS is halfway installed. So i think i just may return the motherboard. You are correct, the reason i got it was because of the price.
