----------------------------

I just built this comp yesterday. my gf is playing aion on this system and its been giving her black screens. she can still here music from the game, but she cant do anything but reboot the computer. she gets DC'd from the game when this happens too. maybe about an hour monitor goes black. she plays warcraft III on the comp too and this doesnt happen. i ran 3dmark06 and it also went black. but i could run it the next try.

i ran furmark stress test and it didnt give a black screen. i ran prime and so far it has been stable. i ran memtest for 2 passes and no fails.

anyone had similar problems or point me at a direction to troubleshoot?

thx in advance

edit:

now im also getting a black screen with white lines....... wtf is goin on. is the card bad? RMA time?

Use driversweeper to get rid of the graphics drivers and reinstall the latest version. I might just be a driver problem. If not then the card might be bad or it is overheating.

If you have a card from another rig or one laying around pop it in, and see if you get the same prob.

i tried driversweeper. still same thing. it runs fine when I only use one stick of RAM. i test each stick one at a time, and everything looks like it runs fine (ran 5 passes for each stick on memtest, no error)....... ran linX over night, and prime95 for 5 hours. didnt get any crashes or error. then i did prime95+furmark for an hour for each stick. no error.

is there a program similar to memtest to check errors in GPU memory?

im also gonna install some other games to test it out. (TF2 and crysis)

 

[drstk]

what does LinX actually test? i know it stress's the cpu, but does it stress RAM too?

I ran it using one stick and there was no error. I ran it with both sticks in dual channel and it got an error in about 1 hour. Im running it again on the other single stick right now, and so far it has no error.

Which Prime95 test did you run? blend or small FFT's?

If you do not get a black screen when using only one stick of RAM, try it with two, but bump the vDIMM a bit. What RAM timings/voltage settings are you using? Try setting them manually if you had them on AUTO.

 

[drstk]

i ran it on blend. ill try setting the timing/voltage manually after this run on the other single stick of RAM with linX.

 

[drstk]

ok.

I did manually set timing/voltage. 1333 * vRAM is at 1.6V * 9-9-9-24

i can run linX with no errors when I run it with just 1 stick of RAM at a time. but when I put both sticks in the same time, linX gives it errors within 30 mins. sometimes at only 2 minutes.

i dont understand how i can run these two sticks at the same time and run memtest over night for 8 hours with no errors........ but linX gives me errors with both in.....

im not getting any BSOD, just black screen crashes when i play certain games (Aion and TF2). i dont lose any signal, it just turns black, or black with faded white lines.

any ideas? if i had to RMA something, what should i RMA? mobo or ram?
