BSOD differents bsod ntoskrnl.exe in many months

Hello,
first thing: this is not my pc, so I have experienced just 1 of this bsod (chronologically the last one: this pc had 2 cd/dvd reader, 1 working and 1 not working, to do some tests, I disconnected the working one, at first start the broken one has worked but it gave me that BSOD).

Another info: after the 30/11 an external graphic card was installed (don't know which driver/version).

All the older BSOD (before the 21/01/2015) was not caused by me. I ask you, gently, to have a look at this dumps and help me to find the problem/s. Thank you

HD3650 + Acer T650-99TZ compatibility issue?

Hello,
some days ago a friend took me his pc because he had got many BSOD (I posted yesterday about that with no luck), many of this BSOD are happened after I have installed in that pc an ATI HD 3650 PCI.

First test group on this machine (Acer T650-99TZ):
prime95: rounding was 0.5, expected less than 0.4 (after 2 minutes)
memtest86: many errors whit 2 stick of ram, 0 errors when testing the sticks singularly
Furmark: test passed with no errors (30 minutes)
hdtune: no errors

Second test group on second identical machine (Acer T650-99TZ + hdd, ram and gpu from the first machine)
prime95: rounding was 0.5, expected less than 0.4 (after 2 minutes)
memtest86: many errors whit 2 stick of ram, 0 error when testing the sticks singularly

Third test group on second and first machine (same hw except for the gpu: here I took out the HD 3650 and used the integrated gpu)
prime95: no errors (in 8 hours)
memtest86: no errors (100% passed)


Ram: 2x1gb 1Rx8 PC2-5300U 555-12 hymp112u64cp8-y5
CPU: Pentium 4 524
Obviously no overclock was made on this pc.
Obviously gpu drivers are up-to-date.

Now i'm trying to donwngrade the drivers of the GPU but I think this won't work, since the problem appear to be an incompatibility between the HD 3650 and the other hw.

Can anyone help me to solve this problem? Thanks

Hi, I'm coming here because everytime I format my computer into Windows 7, it'll show up a BSOD of uncorrectable hardware error while playing games, but in this case, it's Grand Theft Auto - San Andreas. Any ideas? I tried replacing the hard drive, RAM, and updating my graphics card.
