I have a Sony 215z laptop bout 3 months old, It came with XP Home Edition. I left it runin for a lil while came back and there was a blue FATAL ERROR c000021a Screen. Over the next few weeks it would constantly Crash,, The system would also restart its self alot, At this time i did not have any anti Virus protection but when i donloaded and updated norton (NIS 2006) it did not detect any virus's after performing a full scan..
I done a bit of readin and began to belive that It could veryy well be a Software Error, That mabey i had not got somthin installed properly or Visa versa. My next Decission Was to update to XP (PRO) (SP2).. When i installed it straight away i got all the Windows updates and fully installed Norton Internet Security 2006. Thankfully most of my music files and data was still stored on the D: drive! so i fully scanned the D drive just to make sure there was no Virus on it witch there wasint. (WELL NONE DETECED BY NORTON ANYWAYS).
For the next few days my system was runin perfectly with new new XP PRO OS! But then all of a sudden my system restarted its self again. and again, adventually i got the blue screen {FATAL ERROR c000021a} I was absolutely FREAKED that i still had this blue error screen after all the reformating and updateing. I done abit more Readin and found out I could possibly have a Dodgey stick of RAM and that it could be a hardware problem, after fully scanin my system again for viruss, Norton did not detect anywthing and i was convinced this was the case. Untill last night i was down at a friends house.
My friend has a wireless network So when i brought my laptop down it Automatically connected to his wireless network! I still had the blue screen error at this time and was conviced that it was a hardware problem and was ready to send it of for rapair the next day! .. But then his laptop shut down with the same blue screen... He now has the same problem as me system constanly restarting and Crashing The reason that i think its a VIRUS or some type of worm is because First of all before the system shuts down The task bar disapears aswell as the deskop icons and a Error Box with a Message displayin 00:02 seconds shut down NT/Autorised.
The Second reason bein that its spreaded to my friends laptop and hes havin the same problem... So at this moment im thinkin its some Kind of Boot Virus that starts up with the system and thats also UNDECTABLE by norton or windows Security. Ive truly GOOGLED my heart out on trying to find a solution but Can't find one.. Can anyone Help me? Surely there must be expierenced people that have had this problem Before if so Give us a shout Back..
Cheers
