hello again folks. my system specs are - windows 7 ultimate sp1. 32 bit. intel core 2 duo e4700 @ 2.60 ghz. 4gb ram. sapphire radeon hd 6450 1gb ddr3.
i have searched various threads with people having similar problems but not exactly the same one that i am having. whenever i start up the windows after a break of about 5 minutes at the least, windows doesnt respond immediately. i can move the cursor, click the start button but thats about it. when i try to refresh, the cursor just gets busy(rotating) and all i can do is click the start button, and the start menu opens after quite some time. and i have to wait till i can click log off and/or enter task manager as im unable to do it right away. it goes on like this for a lot of minutes. sometimes it allows me to log off. and sometimes it shows me the windows not responding,wait or end process msg. but once i log off and log back in, windows works like a charm. now,i didnt have this problem when i had an nvidia 210gt. i only started facing problem after installing the 6450 card. thats why i believe its the ati card or drivers (downloaded them from amd site) rather, thats causing the problem is because i have tried every other method mentioned in various threads. reinstalled windows, disabled startup and microsoft services/programs,enabled select programs and services, checked registry for errors, ran cccleaner, ran malware bytes, scanned with comp for virus and all that (am using kis2012), and well, a few other methods i cant even remember after trying out so many. i am stumped as what do do or try next. so please help. i am exhausted looking for solutions. cant even remember if i left out some method that i tried. i would really appreciate it if someone can help me with solving this extremely annoying problem.

edit: i dono how i forgot to mention this, but i also have the windows 'blinking' and not responding for a few seconds issue. which ALSO started after changing the graphic card.
 
Solution
your problem may come from the fact you are using an older motherboard that has PCI-Ex 1.0 and the card is a PCI-Ex 2.1, this is an issue with newer cards on much older boards, even if you update the BIOS you may still have issues, the motherboard would be the issue in not properly supporting the video cards full potential an if you read up on how PCI-Ex 2.1 and 3.0 card have issues with 1st generation PCI-Ex ports you will notice this issue, you will need to upgrade to a PCI-Ex 2.0 or later motherboard, which will mean changing CPU most likely as no Socket 775 are PCI-Ex compliant
Did you do a clean install of windows, i.e., complete reformat of hdd and start from scratch or did you do a system restore?

What motherboard are you using and is the bios up to date?

Typically, problems like this occur when nvidia is "replaced" by amd (or vice versa) and the prior drivers and software are not COMPLETELY uninstalled.

Is your rig a self built, or is it a prebuilt like dell or hp?

Please provide your system specs so we can evaluate potential problems areas.

hi mark. sorry for the late reply. got caught up in something.
i did a clean install/complete reformat. the system is a pre built hp sg3470il. 755 lga socket.
mortherboard is msi boston. chipset - p35/g33/g31. southbridge - 82801gb. and as for the bios,well,i have never updated it since i got this comp 4 years back because i dont know how to and didnt see the need to coz the comp has always worked fine. the bios version is phoenix tech, 5.08.
didnt know there were conflicts while replacing the graphics cards. what do you suggest i do mate?

Sigh.

There are millions of people running ATI cards with Win7. I'm running a 4yr old 5850 with Win8, never had a single issue.

If you did a clean windows install, it's not an ATI driver problem.

well, yeah. it might not be. but trust me, i have seen various posts reporting similar problems in the amd support forum with windows freezing at startup after installing ati drivers for the first time. also issues with catalyst control manager. and i might just be one of those people who has this rare problem after shifting to ati from nvida like markwp has mentioned above. its just one of the possibilities i can think of since i have tried out pretty much everything else. perhaps i could remove the card and see if it happens. but if i do, and it doesnt happen, then it would still defeat the purpose coz then i would be sure its the driver problem. hehe. where do i go from there then. it would be like getting back to square one. anyway,in case if its not the drivers,i dono what to do next.

you know what? i think you might have just nailed it. it didnt even occur to me. as i see the cpuz results on my screen, i think you are right. in which case theres nothing i can do i guess. coz i cant afford to replace the mobo at the moment. awww man. ah well, atleast you found the solution. hehe. :) thank you mate!
edit: but i wonder why the issue goes away after the second login if thats the case. hmm.
