This problem started yesterday, didn't install anything suspicious I can think of.
Within the first 5 minutes after start up (Win XP) the pc "freezes". Doens't help if I wait 20 minutes either. Can't move mouse / keyboard stuck / all programs seem to freeze too.

So formatted my c drive today, reinstalled windows xp and worked for like 10 hours but now I have the same problem. Ran 3 different virus scanners (avg and panda, norton online virus scans) but none found anything. Safe mode is working (working on it now for over an hour) and so does Knoppix. I'm running zonealarm as firewall.

If anyone can point me into a direction, I would be very glad. Can't think of anything...

OK, It can be a few things:

1) You had copied important things before doing reformat, and after reformat you unpacked them and used them again - It can be possible that there was an virus in there that still not "found" by Anti-Virus companies or whatever you call them
It can even be a spyware or anything similiar

2) Hardware problem


3) Did you reformat right?


Download these 2 applications and run them, update before running:
Spybot:S&D Download
Ad-Aware SE Download

Then download Download "HiJackThis".

Make a new folder on your desktop, name it "HTJ". Put your hijiackthis.exe into that and open/run the .exe file - Click on "System Scan & Save log, The log are in the same folder where your .exe file is. Copy the content of the log to a new thread in ->
HTJ Forum

Good luck :thumbsup:

I think I found the problem:
When I plug out my network cable (internet one), it doesn't crash.
Still works under safe mode though.
What could that be?
Am I being attacked by a ddos attack or something like that?

I'll follow your advice :thumbsup:

Yes you can be under DDOS attack too, is your firewall saying anything to you?

No, one moment it's all fine (normal traffic), the other it doesn't do anything anymore and stalled.

Hello there and welcome to BC!!

To your problem. It could be your cooling system. Since you said it turns of nearly every 20secs etc...

You might want to check for cooling before you start with anti viruses programs etc..

Step 1
Check the fan. Look if there is any dirt in the fan,if so clean it.

Step2
Check your power supply. Maybe your computer isn't getting enough power at sometimes and just frezzes.

If you don't know how to do that all let me know and i will guide you true it step by step

Regards,
Claudio

I think I found the problem...

Tried all kind of stuff like using another pc on the line, which worked.

At last I decided to use another network card since like I said it only happens when I put my network cable in. Seems to work now.

Strange that it works with the "broken" network card in safe mode though.

Any way I can check the network card?
