PC Reboots while downloading

  Adezzz 18:36 04 Dec 2005

Hi all, Please help. My pc keeps rebooting itself without warning after a random time whenever I am downloading anything. It never crashes when I'm browsing. I use Mozilla, but it happens in IE too, so can't be that. I tried rolling back to SP1 but no luck. I called my vendor who said connection was fine and must be my pc. But I just cannot work out why it only crashes when I'm downloading. I haven't installed any new hardware recently. I reset my modem (which is cable - 1mb). I've checked for viruses and spyware. I use Zonealarm and AVG and clear spyware via Spybot and Adware. This is really doing my head in. Please someone must have had the same prolem as me at some point.

PC spec:
AMD 3200 XP
512mb RAM
256mb Radeon GC
200gb HDD
1mb Terayon Cable Modem (USB)

Have you checked the event viewer to see what shows up ?.

Try saving to a different folder or partition.
Check your HD for errors. Do you have AVG set up to scan downloads?

alan227 - Just tried looking in event view and seems I have a problem with that too. If i click on Apllication, Security, etc, a message says "Unable to complete operation on Security (etc). The interface is unknown". This happens all logs, so i dunno whats up there.

Skyver - I tried saving to different folders. Only have 1 partition. I will do a full HDD check overnight. As for AVG, everything is on. Its also set to search in all infectable files.

Do a system file check, Startmenu/Run type `sfc /scannow`

Are you using Norton AV?

Sorry I've not replied to ur answers. I had to go away last week. Anyway, I've done a System File Check and nothing happened, nothing showed up, no results or anything. Got event viewer working and there are alot of "tcpip - 4226" warnings around the time it crashes. but I dunno if this explains anything cos I don't really understand it. I was wondering if reinstalling xp again over the top would help. Can I do this without losing anything on my pc, games, etc.

I'm not using Norton AV. I use AVG from Grisoft (Free edition)

Your MTU setting for your internet connection may be wrong.Check with your ISP what it should be (usually 1458 for most but 1400 for AOL).click here for how to change it.

Don't know if it will help but worth a look
