How can I update my display name?

New Video Card - screen loosing display ?

• Hey all! I just upgraded from my old GTS 250 to a GTX 560 Ti, and it installed pretty much fine. It worked fine, but I still have my dodgy old screen whilst my new one is in the post. I had an adapter that went from VGA to DVI, so I used that. However it was really loose and the screen kept on loosing connection with the computer. I thought it was this, so I tried on my brothers screen after a while trying to fix it - I had to turn the computer off at the power about 5 times, as it had no display - and it is DVI. I plugged it in, booted up the computer and about 1 in 2 times it will display anything, and if it does display something it will be about 2-3 minutes until it looses display, and I can't see anything. The only way I can fix this is to use my motherboard's DVI connection, and then it runs fine (in low-res version, of course) and I don't know what to do. I reverted back to before the latest update to my video card drivers, but I'm still running beta drivers. They were working fine before - yesterday it didn't loose connection the whole time and it worked the whole day gaming intensively (Battlefield 3 on Ultra and Skyrim on Ultra with texture packs :P) and it wasn't lagging or screwing up - it worked fine the entire day, leading me to believe it isn't a hardware problem. However today, I haven't been able to get further than 5 minutes before loosing any sort of display. I posted this in software as I wasn't sure if the problem is software or hardware, but it seemed more likely to be software. The only hardware problems I can think of is that it has a small chip in the metal saying the name of the brand (MSI) which shouldn't change anything, and it doesn't have 1 clip properly clipped in, but it still has easily enough support to stay there without problems. Any help would be useful - I've run a virus scan, and it didn't find anything, both on Avast! anti virus and Malwarebytes Anti malware - I also used CCleaner to clean out my registries and general cleanup, just in case. Thanks in advance ! Arcaian

• Answer:

  It sounds like a power supply problem. Your computer is struggling to supply the graphics card enough power. As soon as the power supply gets hot, it turns off. The suggested minimum wattage for a power supply in a PC with a GTX 560 Ti is 500W.
