Nvidia Crashing Like Never Before

[SirTibio]

Hello everyone.

I have problems with chrome and firefox. They both make my nvidia drivers crash and then entire OS. I've tried multiple driver versions both beta and WHQL but nothing works. They usually crash at a new tab or a youtube video. I've disabled gpu accerelation and anything with GPUs but they still crash (plus without the gpu chrome is so slow).

Also, Office 13 likes to crash my nvidia drivers and freeze PC. I disabled hardware acceleration, and it works so far.

When the drivers crash or the OS, my computer freezes and my mouse disconnects (the LED turns off) but my keyboard does not (both connected via USB). It was happening both on my previous W7 and now on W8. If there's no cure for it, could you recommend me which nvidia drivers did not support browsers or which chrome version introducted gpu acceleration, so I could downgrade the drivers.

 

my specs just in case:

e8200 2.66@3.2

gts450 1gb

ddr2 4gb

dfi p35 blood iron

500w OCZ psu

 

Note: I have some weird problem with my mobo, causing to crash entire PC when I unplug the S/PDIF port. I was told it might be something my my sound chip on the mobo. Does it have any relevance to this crashes? It worked just fine for few years as long as the cable is plugged in.

 

Update: downgraded chrome to version 26 and nvidia to 301 but its still crashing. Not as often but still. The drivers crash like 5 times and only after some time they finally freeze everything. Installed nTune but it crashes right after I start the program

 

I have no idea what to do.
