So a friend of mine had a bad video card and then I replaced it with the Gtx650 .
I had the computer running for a week straight waiting on him to get his funds up since I used my funds to front him. I also did a reformat. I returned his computer in perfect working condition. He said he was on it all night and how nice it was running. but now today I get a phone call about blue flashy lines. I've had no problems with the computer. any idea's what this could be..
I am leaning towards the monitor or a bad cable, so I am bringing a dvi/mini hdmi tomorrow. He is using a vga cable with dvi adapter. I installed Windows 7 64bit. ultimate a fresh clean install. All up to date, Bios, drivers and windows updates.
As of right now, It was the vga-dvi adapter he was using. I recommended him to buy a dvi or hdmi cable. He did not use the new one that came with the card. He used the old one. So His wife plugged the new one in this morning and said the blue flickery lines were gone. We just got out of work and I am waiting for him to get on it and let me know what he thinks.
