GPU still giving me a hassle

[Icecastle]

Hey guys, so a few months ago I made a thread about a problem I was having with a GPU I received from a friend. It would hang at a BSOD right after POST. I had it tested on another rig and it worked, so I ruled it down to my power supply being poor as I was using a 400W psu. I upgraded to a Corsair CX750, which works wonders with my old gpu, but when I put in the new one it now hangs at POST while trying to detect "4th Master".

I was reading through your original post and you stated that you got a BSOD on post. I'm surprised no one mentioned this but you can't BSOD on post, it's a windows only thing. Either you were experiencing another issue or you were able to load into windows. You need to clarify.

Another note, you should have done a full system strip down before purchasing a new psu. I don't advise any purchases until I have exhausted every option.

"4th Master" would suggest a HDD failure, how many HDD's do you have in that PC?

It would BSOD after post, not on post. I've got two SATA HDDs both work perfectly fine. It boots fine and works properly when I put in the old GPU. I also bought the new psu since its part of the things I'm upgrading slowly. I havent ruled out other incompatibility issues. I havent even been able to install drivers for the new card because I don't have onboard graphics and the computer wont let me instal drivers for a new card since they aren't compatible with the drivers used to update the old card.

Alrighty, so mousemonkey you may be right about a corrupt hard drive or failing hard drive or something. Using the old gpu it still froze detecting 4th master. Will just unplugging the HDD screw up my system at all? I just use it for storage, its detecting the one that has my OS on it.

Well then no problem at all unplugging the drive if it doesn't contain the booted OS.

Okay so I unplugged the drive and with the new gpu its now making it past post, but still not to the windows boot logo. Once again, the old gpu works like a charm. Also to clarify more, its a black screen not a blue screen, because yeah I know you can only get the blue screens with windows screwing up.

So guys my friend came over and helped me with it, even though he did the same things I did, it has been fixed. It now works wonderfully. Thanks for all the helpful suggestions.
