Windows XP unresponsive - takes 30 minutes to boot in all modes

Windows XP hangs on logon screen in all modes.  Eventually it loads after about 30 minutes but is unresponsive -  cpu memory and disk all seem to be working fine - so seems like its a virus/malware/spyware .  

Found some virus files when putting hd into another computer w32 stration. Managed to delete them. Also found suspicious ifcconf.exe is startup RUN in regostry and deleted. When I try and open eventviewer - which opens after a long time - I cannot open any event as I get the error the RPC Server could not be contacted. Also services comes up with an error .

Please note that the system is basically unusable.

Anything you can suggest before I go ahead with a repair/reinstall

Many thanks

back up any files and drivers if need be. if you download stuff from the internet regularly i'd back this up too - either to CD/DVD-RW or another HDD or computer on the network

go ahead with the Reinstall - a repair won't do much in this case

then get yourself some decent software like Zone Alarm 6 [Pro] and AVG Antivirus 7.5 Free (you can get a basic version of ZA for free - but if you can afford it and can be bothered learning how to use it the Pro version is much better (although currently unsupported for Vista)

Remove all peripherals that are not needed.
I had the same problem being caused by a USB Zip drive.
I removed it and the system returned to normal.

has some good hardware diagnostic programs, wouldn't hurt to check your ram, cpu, and hd first.

while I do agree with the the comments Ryan_R made I do need to inform u that if u reinstall or repair install it would be in your best intrest to pullthe ram and the cmos battery. Virus and worms have been known to stay resident in the ram and cmos chip. this is why u need to cut all power to the mobo ie power cord and battery and pull the ram and let sit for 10 minutes.

 worms are computer viruses that use network connections to spread themselves to any connected computer. Normally, viruses are spread along with an infected program, which could be as fast as e-mail or as slow as a floppy disk being passed between two people.

Thanks for your efforts - I did a reinstall. Actually as I said I was looking for a solution that would not involve reinstall/repair

actually you said:

                                             ----------

as you probably worked out - in your case there was nothing worth doing as an alternative to clean reinstall of windows. there are also suggestions that should help you avoid that situation in the future.

Glad everything's back to normal

It's not unusual for a boot disk virus to be hiding in your computer's BIOS chip also! In some cases there is a "volatile" memory contained on the BIOS chip which can be erased by taking out the motherboard battery.

CMOS: Complimentary Metal Oxide Semi-Conductor. Critical configuration information is stored in CMOS. Some viruses attempt to alter this data.

Tunneling: Viruses that use tunneling techniques redirect all hard drive calls between their location in RAM and the operating system. This allows them to bypass any anti-viral products in memory at that time.

as ryan and I have agreed to the reinstall was the only way to get rid of the worm.
