I hope someone can help as im going crazy with this

Computer details

1.6ghz
1024 ram, 64mb built in graphics card (via s3g unichrome pro igp)
XP sp3
motherboard: ms 7142

i purchased a Nvidia fx500 card with 128mb to upgrade as YouTube was a touch laggy on full hd but otherwise it seemed to work OK, for day to day stuff, i thought new card may make it smoother

i installed the new card, updated drivers but the video on youtube became lagging on everything, totally out of sync audio and video, and the computer is slower, so i rolled back drivers but still the same, before the upgrade it was fine.

I removed the new card and tried the onboard, now I have the same problem with old card

Tried malwarebytes scan, there were a few items which I deleted but still the same.

ive tried a repair installation of XP with the new card to see if any files were corrupt etc but no difference.

Then I removed the new card, and tried a malwarebytes scan with the integrated card, but scan was all clear.

So now im using my integrated card, with laagy video, whereas before it was fine.
This is in firefox, tried Chrome and the same. Tried uninstalling and reinstalling flash


Ive been in the bios but can find anything relevant; the cards seem to load and unload by themselves when restating.

Does anyone have any ideas what i can do
