Unstable because of invisible malware

Locked

My computer is unstable. The connection icon is not appearing in the task bar so I cannot understand when it kicks me out.
1 out of 3 times while loading the windows the computer stucks, cursor responding but nothing else.
Soundcard is off.When windows start I can hear the welcome sound but I cannot listen to mp3s or anything else unless I remove the drivers and re-install them. And this is happening every time I open the computer or restart it!
I have tried all possible adremoval programs, formatting several times,installing XP from different sources. Technicians told me that there are ad programs deep inside (where?) they could not remove. That happened during Christmas.Is it possible after so many months and no adremoval can even trace them?
I have opened a discussion as well on this subject.
Any help would be very much appreciated as I have tried any ideas I could possibly have, or heard, or read.
Computer is P4 worked perfectly since Christmas and technicians could not even tell me what hardware I should change to fix the problems. They said though that the hardware was ok.

It sounds to me like you may have bad motherboard or memory chips Reformatting and installing windows should solve any adware or malware problem even in the boot sector. You may want to try a great program that I recommend to all my friends for adware and malware issues. You can find it at http://www.eset.com It’s called NOD32. You can download the trial version for 30 days and it will recognize and major problems within seconds of installation. I hope this helps.

Download DBAN http://dban.sourceforge.net/ and wipe the HDD. (make sure to backup any data that you may need.) By wiping the HDD you are ensuring a clean slate. Now, install windows etc. and besure to put a virus scanner and firewall on the system. Free virus scanner http://free.grisoft.com and free firewall http://www.zonelabs.com Now do all the windows updates to the machine. Also run http://www.safer-networking.org SpyBot S&D and http://www.lavasoftusa.com Ad-Aware. And SpywareBlaster http://www.javacoolsoftware.com/spywareblaster.html It also may be a good idea to have a copy of the ultimate boot cd http://www.ultimatebootcd.com

I agree with Stephan. Is it consistent–does it ALWAYS happen at the exact same place in boot? If yes, test your RAM.

You say “1 out of 3 times while loading the windows the computer stucks”–could it be heat related? If the RAM passes and it happens mostly when the system has warmed up or in different places in boot, your MB or processor could have heat problems.

It sounds like your techs are saying you have a “rootkit” deep inside. But a complete re-install (delete partition, recreate it, reformat complete) should wipe out any rootkit. That rules out software problems. After that, it would most likely be in the hardware described above. Good luck.

To see if you have a hardware related problem you could always download one of the Live Linux’s and boot from that and run the system if it works properly you should then wipe the HDD reformat nd reload after testing your HDD

you can pick any of the Live Linux’s from here to use

To test your HDD you can visit the HDD makers Web Site and download the testing utility or use the Ultimate Boot CD available from here

This has a lot of testing utilities included which may also be of some help.

Also what xpcd are you using? If you have slipstreamed an xpsp1/sp2 bootable cd it could be a virus on the cd.
If the computer is sticking what video card do you have there, windowsxp setup does not carry all drivers natively only generic.
Remove any cards like a netwrok video card so that the install is using only cdrom and onboard video card.
Is this xp copy an OEM version?
You must clean install only. Delete the partition.
The connection icon is not appearing in the task bar so I cannot understand when it kicks me out.
Open your internet connections and put a tick in the show an icon when connected.

If unit can still get on internet google “ewido” download and install update and run a full scan. You can also google “spycatcher express” download install update and run a full scan. Ewido is a 30 trial, but spycatcher express is a free version of spycatcher.
