update:

it's been a while since that update ... sorry for that

but i still have the same freeze

i said before it was the gpu..well i was wrong...coz after replacing my card with a brand new one.. the freeze is still there..

so i thought it might be my asrock mb..i replaced it with a brand new gigabyte m720-us3 and the same freeze happened

so it might be my unbranded powersupply.. i replaced it with hec 450 watts and the same freeze happens

the only change that differs as i try all this is the time interval of the freeze..hehe..though it's random

i replaced almost all my pc exept for the proccessor and the hard disk and the hyperx ram..

and it cant be the ram coz i tried it for 2 days at one of my friends pc and it cant be the proccessor as it passed 24hr prime test and the hard disk scanned and reformated and is ok

after all of that.. i am not willing to change any more hardware parts..i won't spend any more nickle..

and now i am sure it's a software thing...no relation to hardware...

note:
-the games that i tried and freezed "borderlands-batman aa-mohab-crysis-metro2033"
-some games don't freeze like "re5-assassin creed-gta

!!!!!!!!!!

I guess you also reinstalled OS after motherboard replacement?

I must say it is strange that 3-4 games you listed freeze and others do not. Also, do check what are the temperatures of GPU/CPU during these events. As far as I know metro and crysis really stress GPU with all that eyecandy. Perhaps you can lower the game's display details to see whether that helps in some way.

i tried the driver verifier steps but it always gives me a blue screen and reboot on windows start

what can i do now

hope that solves it

i tried to lower the game graphics and it didn't solve anything...

note: when the asrock a780fullhd mb was there i tried to lower all the settings of batman and ran it on the integrated hd3200 built onboard it did'nt crach however it was only 15 frames...shitty play for about an hour...

i hope that verifier thing works on finding what is the problem...

and very thanks to your replies and help

that in my opinion sounds like a driver problem have u tried uninstalling the current driver and then use a program like drier sweeper to uninstall any of the little left overs of the gfx driver and install the newest drivers for your card.

the installed ati driver is the latest with catalyst 10.3

amrdesigns when you said you reformatted your HDD, can we assume you're now running on a fresh install of windows and it's still happening?

Please post your minidumps here for analysis.

You can find them in C:\Windows\minidump

Also, please confirm that whether you re-installed windows (after formating OS partition) when you changed the motherboard?

Hi Bishop1138. Have you managed to solve your problem? Was reading this thread yesterday and realised that you had not updated in 3 weeks. So was wondering if the issue was resolved after reverting your CPU to stock speeds.

Unfortunately the freezes continue for me though it seems that after switching to my old 8800 that they have lessened in frequency, no clue as to why though

Stranger still, I mean I have seen more systems with 8800 series cards with BSODs/Freezing issues, when compared with 4000 series ATI cards. Anyhow, have you tried to use that card in some other system and see how it behaves under stress?

Has anyone tried running memtest86+? Since all else seems to fail just try testing your RAM modules one at a time.

Good point, I will add one more suggestion to Rit's observation, i.e. running OCCT and stressing the graphic cards, to determine whether there is an issue.

i had this problem and it went on for months, with a 8600 gt turned out i didnt have enough power. Dont forget when you overclock you need more power so your motherboard is drawing more for that processor, your GPU is drawing a lot too at the same time, whenever i play crysis my graphics card always freezes up if my processor or Gpu is overclocked i have no idea why but it does. Id set everything back to factory.

i don't overclock my ps is 500 watts which is more than enough for my build

yes when i formated my hdd i installed a fresh copy of win7 and the problem is still there

i tried the verifier thing with selecting all non microsoft drivers and it just gave my a blue on startup and rebooted

after that i booted in safe mode and the minidump is attached

This crash was caused by STREAM.SYS, this usually is used for USB devices (e.g. digital camera etc.).

Which USB devices do you use?

3 devices are always connected to my pc... usb webcam....gamepad..bluetooth set

the game pad is so old and worked for more than 3 years with no problem

the webcam and bluetooth set are about 6-8 months old>>i don't really remember

i will disconnect them and try and tell u..

note: as i said before>>only some games crach while others work with no problem

i am now playing assassin creed II and it's a great game with no craches...

Alright, please keep things updated; and if you get any more BSODs don't forget to add minidumps with your posts afterwards.

In case you don't get any crashes, then start adding disconnected devices one by one, hopefully this will help in identifying the device which is causing this issue.
