as you said, you fitted new parts further on in your post?

Can you try doing a restart from a previous saved point\back up in SAFE mode? Obviously pick a date prior to the mini dump date...

Are you using any 'Ready Boost' device on this system? If so please disconnect it, and see whether that helps. Also, if you have minidumps can you please post them for analysis, you can find them in C:\windows\minidump. Regards

Minidump

Sorry, I should have told you this. My hard drive got corrupted so I got win7 installed again last week.As of the hardware I have only installed a USB Modem for Internet since then. Even today before rebooting I had the same problem.I have attached the minidumps

Your second memory dump specifically cites 'memory corruption (Read Memory Error @ 829b971c, 85b55658)' as the cause of system's crash. Now, that you have added additional RAM to this computer earlier on, may be there is an issue with that Module (based upon the assumption that before that you never had any such issues with pre-installed modules).

Please download memtest, and let it run through the nite (minimum of 8 passes, more is better) to see whether there are issues with RAM and come back with the results. Regards

Hey Archean,

I ran it overnight with 417% coverage and got 0 errors.

That dump was because of MEMORY_CORRUPTION_ONE_BIT which generally happened due to issues with RAM. Sometimes memtest is not able to find RAM errors easily, to stress your RAM further I'd suggestion you to test it on individual modules (i.e. one by one), it'll be pain but it is something which may yield something.


It still there is no error found, get the newer RAM Module out of that system, and try running it with the older RAM for a while and see whether the BSODs happen again or not.

Is your notebook came with integrated graphics (which usually is the case with likes of toshiba) or does it have a discrete graphic solution (e.g. from nvidia or ati)?
