I have a Sony VGN-FW17)J... It started freezing occassionaly about 20 minutes after stratup. A reboot would fix it and it ran fine. Then it would freeze minutes after bootup and restarting wouldn't help. Restore doesn't resolve and it freezes with MS updates. Turned off auto updates and ran chkdsk.... forze before it completed. any suggestions?

I have exactly the same problem started last winter, ran fine all summer then as soon as it got below freezing again if I start it and run for 15 20 minutes wont restart I have to let it sit for 20 minutes or so and then it will start again. no codes and just turns over without starting. cant be fuel pump like i said had this problem last winter then ran fine all spring summer and fall! Anybody got the answer for this one??

hi,can you help me? i have a problem of my sony vaio VGN-NW350F! MISSED base system device!

Memory fault. Check the memory chips.

Most likely your hard drive has gone bad. It could be your RAM too. I know that you said you checked your ram one stick at a time. What if both sticks are bad? I would get some cheap (low MBs) sticks of ram that are compatible with your computer to see if your computer will start to run right with those in.

Try starting up with the shift key down--a safe boot. You will not be able to work with the internet or many externals but this will test functionality. You can run Dish Utility and verify but not fix the disk and repair permissions. Even better would be to startup from a boot CD/DVD and hold down the C or D key. Then you could fix the Disk too.
Next I would save all your necessary files, preferably on an external hard drive.
If the disk is OK, I might remove as half the programs from the Applications, certainly any that are automatically started up. Reboot without the shift key and see if there is a problem. Add half of those back and try again. Half the amount to add or subtract--a binary search. Until you locate the problem program or reach a state you can live with.

Sorry i nay be a month late on this thread... but better late than never. My Girlfriends sony vaio VGN-CS215J seems to be doing the exact same thing. After buying one of those computer fans that you rest the computer oneverything seems to be running normal. i would also recommend cleaning your fans inside the computer because dirt dust and grime can hold the fans back from cooling down the laptop efficiently and will cause the safety overheat shutdown to activate and shutdown your computer... that way it does catch on fire or fry any of your hardware inside of your computer.

If that does not work... your fans maybe malfunctioning or not functioning at all. this model of vaio has a grinding fan issue that can be very damaging to your cpu if not fixed.

hope this helps,

Probably full of spyware / clogged by programs.

Remove / uninstall any existing spyware program(s)
Download Malwarebytes(FREE) / install / full scan / delete all infections.
Ensure you have aPAID anti-virus program installed / update / full scan.

Open My Computer / right click on / C drive / properties /disk cleanup (Tick all boxes) / remove all files surplus / OK it as quite safe to do so.

Perform defragment. Start / Programs / accesories / system tools / defragmenter.

Go to Start / run / type in msconfig / enter / select start up / untick all BUT antivirus and malware program / close / reboot / tick box that pops up upon reboot.

This will absolutely speed up your Laptop. Perform this every week and you will never need for Tech assistance again!! (Except the msconfig one)

To be honest this still sounds like a fan problem. The freeze will happen if the laptop overheats. Maybe you should have it repaired again by a different company.(ask for the fan to be replaced!)

Uninstall it then reboot your computer

Is it new?? Maybe you got one of those editions which were put in kiosks in best buy or stuff. They crashed every 20 minutes and sony said it was "On purpose to keep gamers from playing all day and give other people a chance to play" or sort ....
