I recently upgraded my graphics card and as such had a spare GTX 260 to put in the wife's PC. She plays a F2P MMO called TLBB, which isn't really graphically demanding. However, it appears that when she opens two instances of it, after a period of time the display will just go blank i.e. the monitor says "No output". The computer itself is still running apparently fine when this happens, it's just a display thing. With the previous graphics card, sometimes multiple instances would cause a crash of the program but nothing more. GTX 260 temps never really get above 54 C even with two instances running (as I say, it's not graphically intensive). So, I'm a bit stumped as to why this would happen. Up until I replaced this card it worked flawlessly. I would have thought that if there was some driver issue, it would be able to recover without losing the display. The PC specs are: CPU: Intel Celeron Dual Core E3300 Motherboard: Gigabyte GA-G31M-ES2L iG31 Express Memory: 2GB Corsair Value Select, DDR2 Previous GPU: 512MB Asus HD 4350 Silent, PCI-E PSU: 450W Powercool Modular PSU
Does it come back on? The last few drivers have had problems with firefox and Fermi based cards where the driver stops working but comes back on 20-30 seconds later.
That was my initial thought, but 450W should be more than enough. My previous setup only had a 450W PSU (although a Tagan) and never had any problems.
Should be but the wattage doesn't tell the whole story. In this case one of the rails might not be able to supply that advertised voltage or maybe it cuts out for too long. Might be worth trying with a well known quality brand PSU just to rule it out if you have one spare.
Yep try it with the 600W from your signature PC. Note the GTX 260 can pull more power then the total original PC could.
