Losing time when watching videos fullscreen on my old CRT TV.

Hello.

How come my PC/Windows' clock loses a few seconds per minute (seems to
pause about every four or five seconds for about a half of a second)
when I use CRT TV clone and watching videos fullscreen on my old 20" CRT
TV (from 1996)? If I am not watching videos on it or use single display
mode to my DVI/VGA 19" LCD monitor (1280x1024) with videos, then I have
no problems.

I used ATI Catalyst suite display drivers (v9.7 and v10.12) to clone to
my old 20" CRT TV to show videos fullscreen. I am using an old updated
Windows XP Pro. SP3, 2+ years old ATI Radeon 4870 video card (512 MB of
RAM), Intel quad-core systems, etc.

What's up with that and how do I fix it? Thank you in advance.

Running a video will not affect the time. Time is kept through the bios
only. Windows reports only the time kept in the bios.
While running, the power supply is responsibe with providing a constant 3.3
V to the bios.

Check your bios battery, but doubt that is the problem.

More likely your power supply is being stressed too far while running a
videl causing the 3.3 V line to drop.

Hmm, I used two different CPUs, motherboards, batteries, and PSUs
already. Even if it was the battery, doesn't the PC use PSU for power? I
don't have time losses when the PC is off for a long time (e.g., all
day).

Is that stress same as playing computer games, running benchmarks, etc.?
If so, then I have not seen any time losses. It only happens with
fullscreen video to my TV.

Then, the video card is pulling too much power when the secondary display is
used.

Running a computer card, if secondary is not on, will not stress the
secondary output on the video card.
Same when running computer games.

Does sound like a flaw in the video card using too much 3.3 V power that is
affecting the bios timekeeping.

Does Windows eventually correct the time after a few minutes after shutting
off the secondary display (TV)?
Could be a clone code problem, but bet on the video card itself.

Hmm, I already tried two different good brand PSUs (600 watts SeaSonic
S12 and Corsair CMPSU-650TX 650 watts ATX12V/EPS12V SLI Ready CrossFire
Ready 80 PLUS Certified Active PFC) too.

Hmm. I never had this problem with NVIDIA GeForce video cards (7950 GT
KO was the last one) before NVIDIA decided to yank the fullscreen video
overlay feature out of its newer drivers to force me to go to an ATI
video card over two years ago.

off the secondary display (TV)?

Yes, if Internet time synchronizes with a NTP server and does not time out.

Is it all ATI video cards or just the one I had for over two years? It
is a MSI R4870-T2D512 OC Radeon HD 4870 512 MB (S-video+composite cables
and adapter connected to Toshiba W-627 VCR to a January 1996 20" Sharp
CRT TV). You can see more of my current primary computer specifications
