SVChosts.exe error in Windows XP

I have a windows XP SP2 laptop which when booted up into windows I get the following Application Error - The instruction at "0x7c918fea" reference memory at "0x00000010". The memory could not be written.
The laptop is a Sony Viao VGN-S5XP/B, it has 2gb of memory now, I recently installed a new Hard drive (250gb) and a 1 gb memory upgrade. The problem was happening before all this was installed and has come back even though we did a clean install of the operating system. Does anybody have any solution to this problem?

Try the below code. Save this in a notepad as Svchost_Error.bat, run this. It will ask to restart. If this does not work. Then try updating Windows from Windows Update.

Thats assuming it is a Windows Update service....

There should be an entry in the Event Viewer>System, and Application log, that should provide more info....

Can you paste it here please?

SVCHost.exe holds many services, and until you know which one you are dealing with, I would steer clear of doing mass registrations, folder renames etc....

It is very common for svchost.exe errors to occur if you have an infection, and that needs to be ruled out as well.

Perhaps a HijackThis logfile will assist us. Run the scan and post the log here please....

I would actually do a few things first........Install and update Super Anti Spyware and reboot to Safe Mode. Then do a full scan, and see what it finds. Or, if you prefer, scan with MalwareBytes....

SUPERAntiSpyware.com - AntiAdware, AntiSpyware, AntiMalware!
http://www.superantispyware.com/
One of the best on the market (and it is free, although you can upgrade and get Real Time Protection). Under the Options, go to Scanning Control> and make sure it is set to the following.....

Terminate memory threats - checked
Ignore non executable files - unchecked
Scan only known file types - unchecked

Manual Definitions Download....
http://www.superantispyware.com/definitions.

MalwareBytes
http://www.malwarebytes.org/

Also.....

RootRepeal - RootRepeal - Rootkit Detector
http://rootrepeal.googlepages.com/

Under each tab, hit the Scan button, and see if you get any RED files/services/processes/drivers in the list, or just look for the summary, for any hidden files/services/processes/drivers in the lower left hand corner.....

pspglb - I have done the scans that johnb6767 suggested and I dont have the problem occuring just yet - I will need to leave it on test as in the past it was sporadic. I was eager not to make major changes to the system at first try. I will come back to this thread tomorrow to update you. thanks to all so far.

PSPGLB - We tried your solution and the problem still happens.

Johnb6767 - We ran both malwarebytes and superantispyware, SuperAntispyware found 215 cookies that it removed otherwise nothing else was found. The latop worked fine for approx 4 hours of uptime, but we powered up today and the problem re-occuring - Anymore suggestions would be appreciated.
