This is a long story. In July my Dell 1557 started randomly crashing with multiple BSOD, I gave up on it and Bought a Sony Vaio F23.
It is now doing the same.
I Upgraded the laptop with a Crucial M4 128gb SSD and 4GB Kingston SODIMM
I have had a few BSOD's so i removed the SSD.
Since that point the factory hard drive has also produced 4 BSOD's since the 15th December. All with different codes.
These crashes were caused by memory corruption (probably a driver). Please run these two tests to verify your memory and find which driver is causing the problem.
If you are overclocking anything reset to default before running these tests.
In other words STOP!!!
1-Memtest.
RAM - Test with Memtest86+*Download a copy of Memtest86 and burn the ISO to a CD using Iso Recorder or another ISO burning program. Memtest86+ - Advanced Memory Diagnostic Tool
*Boot from the CD, and leave it running for at least 5 or 6 passes.
Just remember, any time Memtest reports errors, it can be either bad RAM or a bad motherboard slot.
Test the sticks individually, and if you find a good one, test it in all slots.
Any errors are indicative of a memory problem.
If a known good stick fails in a motherboard slot it is probably the slot.
2-Driver verifier
Driver Verifier - Enable and DisableI'd suggest that you first backup your data and then make sure you've got access to another computer so you can contact us if problems arise. Then make a System Restore point (so you can restore the system using the Vista/Win7 Startup Repair feature).
In Windows 7 you can make a Startup Repair disk by going to Start....All Programs...Maintenance...Create a System Repair Disc - with Windows Vista you'll have to use your installation disk or the "Repair your computer" option at the top of the Safe Mode menu .
Then, here's the procedure:
- Go to Start and type in "verifier" (without the quotes) and press Enter
- Select "Create custom settings (for code developers)" and click "Next"
- Select "Select individual settings from a full list" and click "Next"
- Select everything EXCEPT FOR "Low Resource Simulation" and click "Next"
- Select "Select driver names from a list" and click "Next"
Then select all drivers NOT provided by Microsoft and click "Next"
- Select "Finish" on the next page.
Reboot the system and wait for it to crash to the Blue Screen. Continue to use your system normally, and if you know what causes the crash, do that repeatedly. The objective here is to get the system to crash because Driver Verifier is stressing the drivers out. If it doesn't crash for you, then let it run for at least 36 hours of continuous operation (an estimate on my part).
If you can't get into Windows because it crashes too soon, try it in Safe Mode.
If you can't get into Safe Mode, try using System Restore from your installation DVD to set the system back to the previous restore point that you created.

So i ran memtest 6 times, no errors on memory.
One thing to note is that they are different brands
The Orignal memory is a Samsung, the new stick is a Kingston. Both same timings
I have recieved 3 BSOD's in since turning on the verifier.
2x while booting in to windows, 1x random while browsing web.
i have attached them below.
There is one more modification i have made to the laptop which is install a new WIFI card the intel 6200, as it gives better reception than the atheros card.
I have scanned for virus's as well, using Norton Internet Security 2012 & Malwarebytes. Nothing shows up. Its very weird how this is happening on 2 Laptops.
Most of the drivers are the factory installed drivers and everything is
kept up to date using Vaio Care
While using Excel I recieved another crash, d1 again.
they are coming in thick and fast now....
Driver verified and related to your Symantec.
I do notice Symantec which is a frequent cause of BSOD's. I would remove and replace it with Microsoft Security Essentials AT LEAST TO TEST
