XP intermittent freeze/lockup

By danltd ·
Gateway Celeron 700. 512 Meg Ram. XP Home. Computer will intermittently freeze requiring a hard restart. Usually occurs in Internet explorer. Has occurred while trying to access "add/remove programs" and online "Windows Update." It cannot be spyware/virus. After running (safe, syst rest off) both Norton and AVG; MS antispy, spybot, and adaware and finding nothing significant, I reinstalled XP and SP2 from disk on a new hard drive and still acts the same way. (did not freeze during the whole reinstall procedure.) Replaced the power supply. Same problem. Checked/replaced memory. Same problem. I removed the pci modem and ethernet cards and have not had a freeze, but then again it's hard to get online without them. Replaced the ethernet card with a different brand that works fine in another computer. Same problem. Tried different pci slots. Same problem. Any suggestions???

works ok in Safe Mode with Networking, betcha...
did you call your isp just to check they are not funking around with stuff?
did you put back to orig Restore point? to what effect? freeze? work ok for while then freeze?
well of course, you said it cannot be spyware, so it is. betcha. (rdl)
nothing is in the event logs, i take it?
the only thing you can correlate problem to is internet access.
worry you are being rapidly reinfected with the not quite removed fully spyware...
me: you have NO other symptoms other than occasional freeze during internet access. this used to work fine and about when did this start? what changed? is problem getting worse over time?
you: yes, it used to work fine. the only symptoms are thse freezes. i don't think i have any other symptoms. nothing has changed.
me: how about sp2?
you: no, that went on long time ago, no problems...
me: you SURE you not getting hi-jaacked to ad site (you check status bottom left in IE and you go where you expect to?
you: yep
me: you have both dial up and broadband and you have tried both? do both have the problem just the same? or is dial up better behaved?
me: do you scan for adware with internet disconnected? then reboot and rescan? rinse, repeat, until nothing found? do you then connect to internet and things work fine for a while then this problem begins? you have kazaa or any of that type of file sharing program?
what else might be talking over internet hogging processor and pipe? what updates are trying to go off? real player, windows, anti-virus,
(this is what Safe Mode with Networking will test for)
i would have thought hardware also. about the only thing you didin't talk about is the broadband router if you have one.
the hoofprints are all over the place and it is not zebras. it is spyware
you on AOL?
Nortons, huh? what kind of nortons? what version. is software updated? when you do manual liveupdate, says: nothing to update?

re: spyware: I don't think spyware residing on the old hard drive lying disconnected on the table is going to migrate back to the new one thru the air???

Can't system restore to that hard drive on the table, either.

Video is built into the motherboard. No AOL.

Three other computers on the same router work normally.

Norton 2004 and AVG 7.0 both current definitions. They will update online, using internet explorer seems to cause the lockup. But with a totally new hard drive and software install it seems like it must be hardware related.

I'll ask a question: Are both AV software programs installed and running simultaneously? or did ya run scans from boot CDs.

You might have an IRQ conflict between the modem and ethernet card [would cause a freeze]. If you only installed the NIC but not modem and computer freezes but does not when removed, gotta be the NIC. Is it a 3Comm?

Have run both Norton and AVG, but they were not installed at the same time. Only AVG is currently installed.
I have used both belkin and smc ethernet cards with the same result. How likely is it that two cards (that work in other computers)could be bad and cause the same problem?

You've been through all the normal troubleshooting. It's now time for brain storming.

Conflicts between sound/modem/NIC cards are fairly common, but I haven't seen a case where a NIC alone causes problems.

Let's first eliminate driver(s) as the culprit. Are you using XP's built-in driver or one supplied by the manufacturer. If XP driver, uninstall it and try one downloaded from manufacturer's web site.

If not driver, verify that no extraneous mobo devices are enabled in BIOS (e.g. on board modem). With a Gateway PC, I don't expect any. Set parallel port mode to SPP in BIOS.

Install NIC in last PCI slot (fartherest from CPU) if you have not already tried that slot.

What is mobo chipset? Likely either Intel 810 or 815. See if Intel has any updated drivers for XP although I doubt there are any.

After re-reading all the posts, believe that OTL is probably closest to solution.

I was fixated on NIC and did not read original post carefully enough.

Is it safe to assume all of the fans... the CPU fan in particular are running as they should?

Love to hear that 3 other computers on the same router work perfectly, swapped bad with a good ? What kind of performance ? Bad cable/cabling is where I am guessing your problem lies, drop connection/numerous retries will freeze a PC. When it freezes does the router say there is a PC on the port ? Does the eithernet on the PC see the router (Green lights on the ports/yellow usually indicates minor comm problem/no light indicates no connection).

Just re-read other answers/comments, yours struck a cord; Norton 2004 and AVG 7.0 both current definitions. They will update online, using internet explorer seems to cause the lockup. But with a totally new hard drive and software install it seems like it must be hardware related.

Or security settings in IE, is IE set up the same on all 4 PC's ? (have locked myself out of the internet via IE). Also Microsoft not an HTTPS site ?
