Windows 7: Issue with XFX 5670 1 GB

Hello everyone!

i am a new member. i recently bought a xfx 5670 hd 1 gb card....it works fine when i am watching movies or any thing else. but as soon as i play any game (mind it any game AOE even) i get a black screen. i have updated BIOS, reinstalled OS, installed latest drivers, checked the card in a diffferent machine (its working fine)......i checked the temp....35-45 normal and 50-65 in load.

anything else i must be doing.......please help...

Thanks all

Try going to Microsoft.com and downloading DirectX. (Unless you've done that already)

Hello archer. Welcome to the forum.

If you are confident that the video drivers were installed clean and the video card works in another machine then the next most logical causes could be :

RAM - Run Memtest Memtest86+ - Advanced Memory Diagnostic Tool
You can also test for a bad memory module by installing one stick in Slot 1 and testing, and then switch it out for the next stick, etc.

Power Supply - 450 watts is marginal for a high end video card. How many amps does it supply on the 12 volt rail? If it is an older supply it could be even more questionable. They get weaker as they get older.

Check your connections. Reseat video card and memory modules. Make sure the contacts are clean. Check all the electrical connections.

Overheating: Is the case and all the parts dust-free? If you take the side(s) off the case (and maybe blow a house fan into the case) and run the games does the issue improve?

Are you overclocking anything? This includes a factory overclock of the video card.

Try those and let us know what you find.

Thanks for the quick replies.....i will download DirectX and also run the memtest, i will let you know about the outcome.

no luck!

Do you have access to a better PSU to try , I personnally think the PSU you are currently using is underpowered for the graphic card you are using

please correct me if i am wrong, i thought this card do not require heavy PSU.....as i mentioned earlier i tried the card in a different machine and that machine has 450W PSU (mine is same).....i have taken 1 DIMM off my mobo and now my fingers are crossed...........i will update the outcome

All ads for that card I looked at had similar specs:

XFX Radeon HD 5670 System Requirements

• PCI Express compliant motherboard with one X16 graphics slot
• 400 Watt or greater power supply recommended (500 Watt for ATI CrossFireX™ technology in dual mode)
• Certified power supplies are recommended.
• Minimum 1GB of system memory

Thanks all for your replies and suggestions! i just tried removing 1 dimm from my mobo and running on single channel. disabled the onboard graphic card, did a fresh Windows 7 install and whallla i am able to play now without any issues.......... either it was bad memory or the driver issue.

i am happy now

guys! any suggestions, if after removing one dimm my card is working fine, please suggest how can i fix the memory issue (i will get it replaced) but anyother comments would be appreciated.
