Computer service technician should be able to recognize that i guess?

They will have the equipment necessary to test it.

I have been running on 7200GS now for about a 4 days nonstop (24/7) without any issue whatsoever..

I considering buy Sapphire ATI Radeon HD 4550 512MB for like 20$. For this reasons:

-To save on computer service testing my pc. (Do it myself with another card)
Cant use 7200GS because my GF is using it in her PC.
-Sending 7750 back to manufacturer and getting it fixed or replaced, might take a good month if not more ... Meanwhile I will need to use my PC, so Ill buy cheap used card to be able to do so. Guess I wont get much more value for 20$ than 4550 512mb, dont wanna spend too much over 20$ unless there would be great difference in performance for little few $$ more. If u have some cards in mind with even 1gb memory, please let me know about them.


One question: could it be that both my older computers are somewhat incapable to run 7750 therefor both giving same issues with "driver stopped working". They have both now 500W PSU's, & PCIe slots, W7's

In this case I think the card may be defective. Although I have been reading that a lot of people are having issues with the 7000 series cards, Sometimes it takes a while for the manufacturers to get drivers that will will work on all systems.

What do you think about this:

The file aticfx64.dll,aticfx64.dll,aticfx64.dll,aticfx32,aticfx32,aticfx32,atiumd64. dll,atidxx64.dll,atidxx64.dll,atiumdag,atidxx32,atidxx32,atiumdva,atiumd6a. cap,atitmm64.dll is not digitally signed, which means that it has not been tested by Microsoft's Windows Hardware Quality Labs (WHQL). You may be able to get a WHQL logo'd driver from the hardware manufacturer.

Its from Directx diagnostic tool 64. Talks about my display drivers I believe. Could it be related to my problem?

[black-wolf]

No it's just not digitally signed yet by microsoft. That doesn't have anything to do with whether it will work or not.

Is sapphire 7750 and radeon 7750 same thing? I ll try to mess around with different drivers I found on the internet a little.

would amd catalyst 12.4 be suitable drivers pack to install on my card?

[black-wolf]

Shappire manufactured your Radeon 7750. Other companies manufacture RRadeon 7750's like XFX or Power Color, ASUS, etc.

You should get your drivers from the manufacturer's website, that being Sapphire. I linked you to that in post # 2.

Tryied those with no success as you know.

I have question, I will order this card if it will work on my MB. GIGABYTE R545D3-1GI

its hd 5450 card, says it has PCIexpress 2.0 slot, so it should work I assume?
costs little more than 20$, but has 36 months guarantee, so ill better buy new one paying few$$ more than buy cheap used without guarantee, so my question is will it work on my MB? If yes ill buy it.

[black-wolf]

They are backward compatible, so it will work.
