Sony vaio blue screen

Windows XP can cause blue screens on many occasions. Like ram failure, CMOS setting issues, OS problems or by any other Hard ware issues.
1. Make sure the bios settings are ok. It is always recommended if you can run your system with the default settings. To do this clear the CMOS by removing the battery and keep for around 1 minute. and put it back. (While this the power should be removed.) Now try and see if the problem is still go to step 2
2. Remove the RAM & Display cards and clean the contacts with a non dust eraser (dont use erasers with sand, old erasers as this might lead to worse problems.) Now try and see if the problem is still go to step 3.
3. Remove other cards and with out those cards check the problem is still there. Go to step 4 if the problem is still there. If its not there Clean the removed cards contacts with a eraser and fix the cards one by one and check.
4. Try installing OS.

If the problem is still it may be your hard disk, Motherboard or the processor. Better to check with a technician.

Hope this helps.
