Hi there,

I previously posted in a malware forum, and that actually helped with the internet part, but the problem persists:
http://www.bleepingcomputer.com/forums/t/106551/computer-slows-to-a-crawl-after-internet-connection-made/

This happens after a certain amount of time, not exactly repeatable, but close to 10 minutes or so. The program, whatever it is (firefox, ie, acrobat, photoshop, etc.) will slow down response time for things that *should* be instantaneous. i.e. clicking from one tab to another in firefox.

I've noticed that it happens more often if I try to view a video online or offline.

There are no error messages, but the slowdown is so bad that I cannot work on the machine anymore, so I set it to hibernate. If I let it sit for a while and turn it back on, it runs fine and snappy for a while, then slows down again. Simply typing in this text window becomes unbearably slow, till I hibernate and let it cool off.

I have downloaded speedfan and EVEREST to try to guage temperatures and they say about 42-44. When I play a video, it goes up to 46-7, then everything slows. Even after the temp reverts to 42, the computer stays slow.

As mentioned in the topic above, I've already put new thermal goop on the CPU. (maybe I didn't put enough?)

I'm wondering if it's the CPU or perhaps the graphics processor overheating? I looked at the mobo (not easy on a laptop) and didn't see the Nvidia chip offhand or another cooled chip other than the p4.

Thoughts?

thanks,
dean

How much RAM do you have, and how much free space do you have on you hdd? If your hdd is too full you lose the swap space needed for it to navigate and will slow down when programs that require more resources than normal, this is exasperated with a low amount of RAM.

Another thing to check is if the computer is clean inside, look for accumulated dust on the CPU heat sink and fan assembly, if you see dust bunnies inside it is time to clean it out. Canned air from you local computer shop will work well for this. Also check to see if the grill for the air intake is clean.

This is one time where less is more. You need just a small drop, spread thinly over the processor. Was the heatsink/tube reinstalled securely?
When it starts to slow down, open up Task Manager and see what all is running

768 MB ram
5,83 Gigs free on HD

probably shouldn't be a problem, right?

When I took it apart to add more silver goop i blew it out with one of those air cans.

Thanks for the tips... any other ideas?

Hmmmm. I must say that the quantity squeezed onto the CPU was NOT a drop, and more like a free form Jackson Pollock painting with swirls and circles. There is likely WAY too much paste.

Any Ideas on how to clean it off other than wipe with a lint free towel of some kind?

I'll pull it apart and re-apply. Thanks.

I used Isopropyl (rubbing) alcohol and a paper towel. Seem to work ok.
