Random reboots
-
I know this is not a tech support forum and i'm not treating it as such, but since you guys always try to keep up with the latest and the greatest in terms of hardware, i'm sure someone would have experienced at least a few of the problems i have to deal with right now. My Mom was given a relatively new machine as a partial payment by a client of hers (a creative way to get rid of a machine they no longer needed, and my Mom was okay with it), though not really related to the work we do together, but in the end, since my Mom prefers only laptops for her work and saw no use for this thing, we decided that this machine will go towards updating my work setup. Looked fine at first, 3.00Ghz P4, 1GB RAM...quite an upgrade from the the 1.2(?)Ghz, 256Mb RAM laptop i've been using for the last two years. There wasn't really a need for anything faster, in fact i miss having two monitors at once (i'll have to wait another month or two, unless i try to fix one that's been having static problems), but when it comes to graphics work, i do feel the difference :). But when i finally made the switch to this machine after re-/installing all my work-related stuff i noticed the random reboots. At first they happened while i was taking a break, so i assumed it was Windows Update rebooting without my permission, so i went and turned that off. It happened twice again when i was in the middle of work, so i went and checked what could be wrong. Assuming that it was a short, i went and took it apart completely, finding three loose screws under the motherboard. I assumed i could now relax, but soon found out this didn't cure the problem. At first i thought it may be a problem with the PSU not grounding properly and the static building up until it discharged after approx. 3.5 hours of run time, as it always happened. But throughout the whole time i've had this machine, it froze twice without rebooting, so it must not be anything electrical. I'm now starting to think they gave this machine away for that same reason, it being an exceptionally unstable setup. One thing i did notice though, is when i do something that's at least mildly CPU-intensive, the CPU fan slows down, which makes me think the CPU draws a lot of current and leaves too little for the fan, thus causing a heat problem. It matches what another guy i talked to on Saturdays said, though he said that newer machines have thermometers that shut off the system at a certain temperature. So assuming that's the problem, do i need to get a bigger hunk of aluminum? Or a better fan
Maybe if it IS an o/s error that causes a reboot, then it's probably because i used my backup copy of the XP disc, which was burned while the PC was lying on its side. If the windows installation program doesn't scan for missing bits or errors, (unlinke that of FreeBSD) then i'm not surprised... Roswell

Run MEMTEST x86 :) Also, watch your CPU tempature / CPU fan RPMs while working. I once had a problem where after some time the power supply would lose charge and slowly the CPU fan would stop spinning. It eventually got so bad it only lasted 10 seconds a boot. The more I unplugged, the longer it ran, but never forever. New power supply solved everything.

Sounds similar but not quite the same...i'll try another PSU as soon as i unpack everything Roswell :)

I have a similar problem. Not quite random, but I get reboots on my machine when I plug my Logitech webcam in to the USB port. Just resets the whole machine just like that. Latest drivers & software for the webcam - unbelievable! And yet on my laptop the webcam works fine. Both windows XP pro with all updates. Obviously a hardware incompatibility (I'd say motherboard). It's absolutely frustrating... it seems like this types of major problems would have been a thing of the past by now!

The only way to stop it is to tightly control the platform. So long as anyone can write a driver and sell hardware, some of that hardware will always have issues with Windows. And people will continue to blame Microsoft.

There is a well known problems with capacitors going faulty on MoBo's. The fault you describe sounds like this problem. Do a google search for more info. Its basically a problem related to poor electrolytes used in the low ESR caps. These caps are used in the power supply on your mother board. Yell out if you cant find the info and i will track it down for you.

From what I remember, some company stole the recipe for the 11 secret herbs & spices another company used to make low ESR caps, but managed to mess it up, and sold many thousands of counterfeit, dodgy caps, mostly to motherboard makers. You can usually tell by looking at all the caps on the motherboard and seeing if any are bulging or leaking brown scabby stuff... I had a dozen or so PC's die because of leaking caps, but that was back in the PIII days, I thought it had all been fixed by now...

Yup, coming from a driver background I agree completely with what you're saying. It's not that we did a shoddy job of testing our stuff or anything, but it's REALLY impossible to test for everything under the sun ! I've always felt guilty that MS got bad press for something they were not really responsible for. But I wonder, if the PC platform had been tightly controlled (like the Mac), would it be as dominant ?

I have a PC that has always had a random reboot problem, i.e. a BSOD. I have never found the problem, unlike yours it can run for months with no problem, then I get several a day. It is a dual boot machine NT and XP and it fails in both Operating Systems. It does seem that certain programs trigger it, e.g. Firefox. It has even flumoxed one of my hardware friends! I would suggest you send it back, i.e. a broken PC is not a valid payment.

Try this: 1) Removing the cpu HSF 2) Cleaning the existing thermal compound off both the cpu and the heat sink 3) Re-apply some thermal compound to the heatink - you only need a very thin layer 4) Re-install the HSF. Some other notes: A) The cpu fan should NOT slow down during cpu-intensive tasks. If anything, it should speed up. B) DO NO attach the fan to a drive connector. Most motherboards will shut off if they don't detect a fan on fan header 1. C) You may want to invest in a better HSF unit. I would recommend the Thermalright Ultra 120 if your case is big enough to support it.

the slowing CPUfan would IMO indicate a power supply problem. eg the PSU isn't able to supply the needed wattage and the voltage is beginning to sag. Once it gets to a certain point the CPU is undervolted to the point it becomes unstable and the box falls flat on its face.

Well, Thanks for the tip :). I mean i never knew that since the machines that i actually get to mess around with (other than repairs for other people) are much older than this, either retired or salvage. The newest one that i had was an 800Mhz PIII but that died a few months ago, when the power supply failed and knocked out the CPU (the caps were bloated so the whole thing was no good, except for the heatsink, power switch and the CD-Rom:rolleyes:). Then i have a 633Mhz with a faulty board that's just sitting there for now. And i also have a 500Mhz desktop box, an HP Vectra, which is probably my favorite, that i've fitted with a much bigger heatsink that's got a high speed case fan wired to the top. The last one is a Gateway G6, with a 300Mhz Zif card PII, which is just there to run diagnostics on salvage drives and will become a Linux-based router when i'll have the time. It's clearly a budget box, so it's got a strange design where the power supply exhaust fan is directed at the heatsink to keep the CPU cool. I felt it wasn't really good for either, so i removed two sides of the PSU (and covered them with onion sack) to keep both in tip-top shape:laugh: So you see, neither of them has its own thermometer, and temperature always meant sticking your hand in the case and feeling the heatsink. The HP ran hot when i first got it, but when i was done with it it ran at around room temperature even at full load I do remember a time when a client's machine had a faulty board and it would spin up the fan but not detect that it's going and turn off half way into the boot sequence, and then not boot unless you pulled the battery. But it also had a bad IDE controller chip, so the board just had to be replaced anyway. Roswell :)

the slowing CPUfan would IMO indicate a power supply problem. eg the PSU isn't able to supply the needed wattage and the voltage is beginning to sag. Once it gets to a certain point the CPU is undervolted to the point it becomes unstable and the box falls flat on its face.
