OT: Main computer freezing at night

[Ken g6]

My computer has hard-frozen the last two nights. Just green lines running across the monitor in the morning, and no production while it was frozen. 🙁

I have a 😱 Compaq 😱 Athlon XP 2200+ @ the default 1800MHz.

Which of the following looks most amiss to you? (Cut'n'paste from Sandra):

Board Temperature : 34.0°C / 93.2°F
CPU Temperature : 57.0°C / 134.6°F

Voltage Sensor(s)
CPU Core Voltage : 1.62V
Aux Voltage : 2.56V
+3.3V Voltage : 3.31V
+5V Voltage : 4.92V
+12V Voltage : 11.86V
-12V Voltage : 0.56V
-5V Voltage : 4.05V
+5V Standby Voltage : 4.92V

I've been thinking about a new PSU ever since I got the machine, but is heat a more likely cause?

Your cpu temps are well in range.

I've had such a problem... Turned out to be the fan on the gfx-card running too slow. 🙁
I replaced the fan --> No problem anymore. 🙂

EDIT:
BTW. it was a geforce2, in case it matters... Can you check the temp on your gfx-card?

 

[Ken g6]

Graphics card is integrated on the motherboard. S3 ProSavage DDR. :roll: No temp listed, but I doubt that's the problem.

Edit: And did the rest of the computer freeze up when the graphics card failed?

 

[amdxborg]

These problems that occurs so irregular really sux! If you can, maybe swop some ram, psu, or whatever is swoppable. Any swollen caps on the mobo maybe?

 

[BlackMountainCow]

Was it the first time this happened or can you somehow reproduce it?

 

[JonB]

If you run with the case open, do the temps drop? And, does it make it through the night?
While the CPU temp is within spec, its still a bit high.

Yes, usually it did...

Bad 5 volt Rail, new PS with beefy 5V should fix it.

-12V Voltage : 0.56V ----- Typo ???
-5V Voltage : 4.05V should be much closer to -5vdc ... .95 volts is a BIG difference
+5V Standby Voltage : 4.92V

Just a thought ...

Sandra is not always giving correct info, especially on Voltages, so wouldn't trust any of the reported numbers. Instead, take a look in the BIOS.

Oh, and just a couple of examples of how bad Sandra is:
On one computer, -5V is reported as -14.91V :Q
On another, -5V is reported as 0.13V, and +12V as 9.18V... :roll:

Now, the -5V and -12V is AFAIK not normally used for anything any longer, but +12V is used for many parts of a system, and wouldn't run with so low voltage. Looking in bios or using a voltmeter, the actual is as it should be. 🙂

I don't think my BIOS can actually read those things. Anyone know where to get a more useful (e.g. can modify ram timings, etc.) BIOS for a Compaq?

I noticed the HD light had been on when it crashed before. I had an auto-backup running every night, so I modified the batch I was using to spin up the hard drive I back up onto, then wait a couple minutes before doing the backup. That seemed to help last night; no crash, so I'm crossing my fingers. 🙂
