YOU ARE VERY WRONG. The CRT does store a high charge of up to 30KV for days.

Regarding the handling of CRTs:
This is not something that an amateur should even consider. It should only be done by someone with the proper training and experience. I won't go into any details because at the end all you would have is a little knowledge. And as the saying goes, a little knowledge is a dangerous thing.

Over the years I have replaced many CRTs so can speak from experience.

After doing some research I will agree that a CRT can store voltage. I wlways grounded the flyback connection to the CRT before I handled it so both the flyback and now I know CRT did not have any voltage. Working on broadcast monitors I once got zapped by putting my hand to close the the HV while it was on.

Other general advice is wearing rubber boots and use a single arm (and doing this with a friend). This will prevent the current from going through your arms or discharge through your feet (passing through the heart in the process), and the friend will be there to rescue you in case of electrocution (knowing Basic Life Support procedures would be optimal for both, any first aid manual has them, if you saw at least one episode of Baywatch you should know them as well). They call it "the buddy system". Never do something dangerous alone. Remember the movies.
If you get a discharge with this setup it will be painful and you may lose sensitivity/movement of the finger/hand for a few minutes. Better than dying anyway.

I don't use rubber gloves as I drop enough stuff already, with gloves I'm less precise than a 90-year old with parkinson.
You advocate dropping a CRT and PSU into water to discharge them? I wish you luck with that method.

When I've called my ISP (Comcast/Xfinity) they always tell me to turn off everything for 2 minutes. I've got ahead of that, I turn it all of before I call.
"Mr Britton I don't see your modem"
"It's off because you always want me to turn it off no matter what the issue."
"Turn them back on please."

No, I just said I gently drop PSUs in water (in an iron container on the grass outside) before disassembling them to see if there is something fixable (usually to change the fan). You have a better idea? I cannot reach the capacitor's contacts in any way before it's fully disassembled and I'm not going to take risks. I'd rather risk damaging the PSU than myself. I can guarantee that it does no damage to PSUs (if you take the time to dry it well with fans before assembling it again and powering up).

I don't know about CRT, but I suggested it because in case you cannot reach the contacts due to casing or whatever making the disassembly at risk of electrocution, water could be a solution.

RC hangs ~every 4 seconds for about 2-3 seconds
Pretty much the title here. Except sometimes it will work just fine if I'm not doing too much. The startup also hangs after the splash logo to the login screen for about 10 seconds. In build 7000, there was no lag at all. Any ideas? Driver suggestions? Not sure.... Thanks!
