pc crashes when instances of ie9 are open

ok this has been going on for a while now, and it's only with internet explorer 9 open.

if i open a single instance of ie9 it will work fine no issues, if i split or open a second instance of ie9 all hell breaks loose memory faults appear to occur for no reason and kernal power failures..

now i can do the exact same thing with safari chrome firefox and opera and no problems occur at all. i can open 4 games do a full render in 3ds all at the same time as watching a movie and streaming content online and chatting on steam while talking on skype, yet if i open ie9 well it all comes crumbling down around me.

so the common area is ie9 as when that opens it seems to just create problems with it closed my pc runs like a dream for weeks on end no issues faults or problems.

now i know the easy solution is to just not use ie9...the problem is i kinda like it, i'm not a fan of chrome or some of the others i've yet to really give firefox a good try though.

so i need some help with this it's driving me nuts now after 4 months of doing it i've changed ram, power supply all my cables twice as i thought hey they could be the fault yet the problem remains

any help or thoughts would be appreciated.

Have you tried re-installing IE9? How do I install or uninstall Internet Explorer 9?

Fix Internet Explorer issues to make IE fast, safe and stable may also be worth looking into.

Fix Internet Explorer add-on problems when IE hangs or freezes is a good fix it, as well.
