Computer Question (Par. Port Causes Crashes?)

Good evening,

it's computer time for me again. This time, I'd like to know whether a faulty parallel port could possibly cause spontaneous system reboots.

Symptoms: the PC I'm typing this on sometimes crashes spontaneously, without warning, and simply reboots. The reboot may repeat a few times and eventually work out. I have the suspicion it might be caused by some fault in the parallel port, the reason being that once I disconnect the printer (as I have at this time) it seems to run solidly; I haven't witnessed a re-boot without the printer connected yet.

I have also de-installed the software that came with the printer (HP LaserJet 3030) and removed most of its residues such as registry keys and values, some I could not delete. However, I don't think it is the software but the port itself - the computer had shown the exact same problem earlier when it was still running Win98 as opposed to XP and had a different printer + scanner (both via parallel port) connected to it.

It wouldn't be much of a deal if the port was actually faulty since the printer has a USB port, too, but I'd still like to know if a fault in the parallel port could be causing this.

Thank you for your time,
aloges

I had that with my old computer - turned out what was causing it was the processor was overheating, as it did not have any gel between the processor and the heat sink.

Another thing that my old computer had was that I fried some memory blocks when I put new ones in. A friend gave me a programme that checks if your memory is working ok. As it would crash every time it tried to access the bad memory.

Edit: Come to think of it, a computer at work I had that was connected to a plotter via parallel port had that - it wouldn't work if the dodgy printer was on. Must have been shorting something out I reckon.

Hope you fix it!

Ouch. That wouldn't work for my processor for a second. I've got one of those calculating room heaters, i.e. 2004 3.4 GHz Pentium 4.

That's quite the usual thing with fried memory. Wonder if it's any good with mayonnaise...

I'm quite positive it's the port itself. I've plugged the USB cable in, parallel still out; prints fine and it's been rock solid so far.

Aloges,

If it looks like a duck...

The only other thing I'd do is replace the parallel cable, if that doesn't solve it, just use USB as you have proven it works already.

Yup. I had never heard of a parallel port sending a PC into deliria, but you never stop learning.

Quoting TedTAce (Reply 4):

Would have been nice, but the problem was just the same using a different cable with different scanner/printer attached... blergh, fried parts of mainboards are never good!

Yes again, although it seems like my attempt to push the decider in this case (sorry, GWB  Wink ) towards a more up-to-date DSL router was fairly succesful, which means I'll be able to integrate the printer in a LAN (via USB) anyway. No need to worry about parallel ports anymore! Big grin

Hell, why do I always set up the good stuff for other people?!?  Silly

I had once traced a similar problem to the keyboard! The keyboard was causing the PC to reboot or freeze, cant remember exactly. So yeah, why not, it could be the parallel port or the printer I guess.
Try the printer on another PC, if it doesnt exhibit similar problems then the problem would most probably be from the port and not the printer.
You can try changing the settings of the port in the bios.
Maybe you can also get something like an addon PCI card with parallel ports, or a parallel to usb adapter, is such thing exists...

Or just get a new USB printer!

You cannot be Klaus.

Klaus would suggest a much more satanical and homicidal end to a wintel product....

Yes, they do exist.

Not quite feasible since that printer is a laser all-in-one, magnificent machine and one hell of an expensive toy for a home user... shame it's not mine. It does work fine now, via USB instead of parallel.

I've got a box here with the 3.2 GHz room heater, and it was doing the same thing before I took it offline--are you sure it couldn't be a thermal issue?

BTW, I think I'm going to re-seat the chip on mine and replace the heatsink with a C150 engine.  hyper  Meanwhile, the Mac is humming along nicely.

My dual Xeon (3.4s - double the heat) spontaniously reboots. When it restarts, it asks if I want to send the error report (XP). I send it, and get the message that my video card driver is sending a stop signal. Stop signal = blue screen or automatic reboot. If your not getting the error reporting box, I don't know what to tell you, it could be anything.

Thermal problem . . . . possibilty.

Also, I've had this problem with my computer because of static electricity.

Anti-Static wipes help, but proper grounding is the ticket.

It would not be unusual for my computer to spontaneously reboot a half dozen times in a a two-three hour session on line. Because of static electricity.

Lol, guess I did manage to be confusing. The 3.4 GHz one is my own computer, the one rebooting spontaneously is a different machine.

As for my machine - it doesn't really cause me much trouble, except for the hideously cheap WLAN over internal USB "solution" ALDI used when they built the thing. And the heat sink and fan were the first things I replaced... went from 707 to A340-600. Big grin

I too wonder what Windows bases these reports on; if you get one it will be reasonably easy to find a solution, but if you don't... Well, the reboot issue seems sorted now and the printer is working via USB. Hasn't crashed since I stopped using parallel.
