HP 4706c freezing up - Need upgrade suggestions

Hello

I have an HP 4706c pavillion with:
- Mobo-Asus M2N68-LA (Narra3)
- CPU - AMD Athlon 64 X2 4400+
- RAM - 3Gb Speed: PC2-6400 MB/sec
- 300W PSU
- GPU - Radeon HD4650 (I think - the ATI app
reports a 4600 series with 512MbDDR3)
I am having Company of Hereos freeze up - audio continues
but no video change. I am using medium type
settings on the video options.

The windows performance tool says I use a consistent 90% of memory.
CPU & page faults seem reasonable.

Do you all think this freezing is due to a memory constraint or something else?
If you had to spend either $100 or $200 what you recommend I upgrade?

I always deeply appreciate the gift of good insight on
forums like this - thanks in advance

Larry

    Welcome, Newcomer. If you're using Vista/7, press Ctrl+Shift+Esc to bring up the Task Manager. Click on the Performance tab. Click on the Resource Monitor button.
    Find out what the biggest RAM consuming app is.

    90% RAM usage is very high. At idle, Windows uses ~5-10%, depending on things like the version of OS; pre-installed software (from prebuilt systems); system services; etc. Given this scenario, a RAM upgrade might be in order, but if you're using a 32-bit OS, 3GB - 3.75GB is the max usable.
  2. Thanks for the answer. I ratched down the video quality on Company of Heroes and its now ok. However, it sure seems like I had to throttle it back alot for my card capacity. What features of graphics - anti-aliasing, shadows etc use more CPU and which use more of the GPU?

  4. Anti-aliasing uses more GPU RAM, but shadow effects are also heavy hitters. You're not the first to experience this trouble. Often people don't really research into GPU performance before buying. To give you a better understanding of how performance is gained, read this article:
