Lag when i play games

TV needs thorough cleaning up and service.

High DPC Latency WHAT OS???????????????????
what Zd8000 is this, full model name on the service tag.
pC come in submodels, mine has 6 processor choices, ram size and video GPU chips,. offered on one submodel.
we cant guess what PC you have, nor its upgrades
nor what OS you are running. NOW, nor what it came with new.

id bet it's infected , run ESET, off line scanner yet, its FREE
If XP it for sure is INFECTED, as ALL are now. XP is dead now.
no support for 3 long years, and is a virus magnet.
and very very powerful.
and run full Malwarebytes, next.
if it ran before, and not now, it is infected.
or overheating.
or got tons of startup progs, loaded ,
what is the service tag data.
are you running the original HP software?
that means not upgraded to w10.
nor using MS disks to install OS , only HP works right or f11 key
reinstalls.
lag. (tests that help prove what it might be)

1. lags on playing C: test.wav file>
2. lags playing C: test.mp3/?
3. lags if you click test windows sounds, in CP + sound
4. LAGS OFF DVD MOVIE?
5. LAGS ONLY ON OLINE
6. LAGS ON ms solitaire?
7. lags on DVD loaded local games?
8. lags only on steam games....
9. lags only on live web games
10. my guess is it lags from even just sounds. (even music online or off line, not just Video lag, as all on line videos can do.
11. even my netflix lags on my TV with 200mbs/ fiber. (and has nothing to do with my systems, its the internet or netflix caused.

The DPC spikes, my guess are software overload.
too many things running or
how many cores is your processor have?
i looked up on pc like yours,
it had and old Pentium 4.
ATI Mobility Radeon X600 with 256MB dedicated
are you on wifi or fast broad band, with ethernet direct connect./.
but this pc has no gigalan jack, oops, that be bad.
running XP are you>?

first try this on this old dog pc

in the start box. type, msconfig.
then see startup tab
then shut them all off for a test.
see if runs ok now.
why not show one example in detail that fails
show slow video link online. a youtube.
or better , name a game that runs slow or lags
nAME JUST ONE Thing,
tell where it resides.
1: HDD , folder. local.
2: CD/ or DVD drive.
3: online, games.

we cant guess what you do exactly so please say so.

what Id do with this pC
is give it to GOODWILL (tm) then walk over to the newer Laptops
and get one with w7 or newer
and WIN !

Depending on your model, this is caused by visual post-processing which may introduce lag. Many LCD diplays have a "game mode" setting make sure this is on when playing your Xbox 360 through this LCD TV. Also, depending on your model of TV, there are motion enhancers (usually proprietary e.g. LG calls its TruMotion) which can also introduce lag; these should be turned off while playing. Another step that should be followed, is to turning off any set video setting in the Xbox's configuration (i.e. turning off any set video output such as 480p, 720p, 1080i, etc.) and setting it to "Optimal Resolution". This should allow for native video output instead of possibly upscaling which would in turn induce lag.
This should correct you lag issue for most common LCD TV's. Hope this was helpful. Thanks for visiting FixYa.com

when you play the game turn your graphics down and it will play better like 1260x800 turn it down to 400x 600

use any othere webcam software.. and use VLC player for playing videos...

If you want to to try it out try it.but lags in dynasty warriors 6 are normal like mine i have 2-6 it works fine but it lags sometime but it's normal.

if your playing on seperate xboxes,then its probably because your internet is doing too much at one time

try adding the /prefetch:1 command 2 the game start shortcut
example C:\program files\game\game.exe /prefetch:1

this can force faster retreval of sum documents and games bt nt alwase

What kind of TV do you have? I've noticed that when I played GH 3 on my plasma TV it lagged until I calibrated it. You might need to change the TV scale to 480p since wii isn't high def. Hope this helps.

I'd recommend the latest video drivers- and strangely enough- defragging the hard drive. Most laggy systems I've seen with plenty of ram (512 or more) that have no spyware on them, and no major ram eaters (norton, spysweeper, mcafee) are fragmented. look in task manager (ctl, alt del) and see how much free ram you have- and see what is using all of it. If you have a lot of ram, and no process is chewing up the ram, or the cpu- then defrag the hard drive.
