GPU reaching the end of its life

[prophet]

I had my GTS250 512mb since early 2009. For the first year of its life it had a overheating issue I replaced the cooler and it was solved. In January I bought myself a 23inch dell monitor. Last week I bought Dirt Showdown and when I play the game my screen would just switch off. I installed new drivers and the same kept happening, so I tried Shift 2, worked perfectly last year and the same happend. Last night it started happening to MW3. This morning it failed furmark after about 5 minutes, So I guess its time to say goodbye and Invest in a 560 . If you have any ideas on how i might fix this short term I would appreciate it.

replacing it at this point is the better solution. You'll be getting dx11 capability, more gfx memory and a card that can run games better than the 250 did.

You know what you need to do and are just delaying the inevitable.

Ok thank you, at the moment my budget is not great, I can at best afford a GTX550 or a HD6790

Even so a gtx550 will be better than buying a fan to cool your current card at maybe half the cost and it doesn't guarentee it will live.
