Blahh. I had 3 PCI devices constantly sharing IRQ7 (which happened to be VGA
IRQ) in my PC back in the day when I ran 3dmark 2001 and such benchmarking
programs, I scored 7100 with the card (good for its time), no issues with
any program at all. It's not dangerous to share the video card IRQ, most of
the time it can't even be avoided if there's a bunch of PCI devices in the
system. If there is a problem it's due to faulty hardware which should be
returned to the place of purchase.

*Highly* inadvisable, error correction is there to CORRECT ERRORS. If there
is no error correction it could lead to data corruption and/or system
crashes = BAD! Even standard USB runs at 60MHz signalling rate, ie very
susceptible to interference. USB2 is several GHz. Especially over a long
cable, you do NOT want to turn off error correction...
Besides, I never saw such an option in the hardware manager.

Never bothered with those programs. OS runs just fine anyway. Strange, eh?
Sure some might be gained by using these programs, but something might just
as well break too, and is it worth the bother to download and install these
tools and then risk corrupting your registry (which these cleaners CAN do)?
IMO, no.
