Videos freeze and jump

[GizmoFish]

I'm pretty new to this game but have been ripping my hair out with this problem.

I have a PC based on the SiS chipset with a Celeron D 2.4GHz and 1GB RAM. There is an Nvidia Geforce FX5200 with 128MB RAM added in.

Problem I have, came about when trying to play video files. Both Mpeg and AVI show the same symptoms, CPU 100% and video just jumps all the time.

If I disable the audio driver, mpeg runs a treat, AVI slightly better but then it just totally hung my PC. I've tried everything including updating to latest BIOS, changing video driver, even tried a different video card. Updated to latest directx and divx codec, still the same.

What really worried me though was when running memtest from a bootable CD, it hangs my system every time at different places. Tried removing alternating memory sticks and it still locks.

I'm guessing that a rebuild is pointless.. is this a hardware failure? and if so, what's most likely? or is the BIOS doing something wacky with the RAM that's affecting the video card(s)?

Thanks for any help.

welcome to the forum

unlikely it's a codec issue, but start by playing your files with VLC to rule it out

if VLC has the same problem let's look at the memory and how your bios is setting the timings
