Hello everybody. I have a casual gaming/chilling pc. The specs are as following :

Amd a4 7300
4gb ddr3
Asus R7 260x 1gb ddr5
Gigabyte F2A88XM-DS2
Stock 550W psu

So i recently bought the r7 to change my old gpu. Did a clean reinstall of windows 7 64, updated all drivers from the manufacturer`s sites. The problem is that, randomly, the screen freezes and then black screen, shortly followed by a reboot. Appears to happen when i am in desktop, browsing some internets and whatnot. Other than that the PC works like a charm. Also, on top of that, sometimes, when the PC enter sleep mode, it becomes unresponsive to the wake up "call`, even if the PSU fans are still spinning ( not sure about the CPU fans - will give a look and come with an update if needed ). I must mention that this didn`t happen with my old GPU. I can send back the r7, however i wouldn`t like that, as i bought the card at a supersale and at a very good price. Is there anything i can do about it? Feel free to ask any questions about any additional information. I will try to provide them as accurate as possible. Thank you :)

I used to have the same sleep mode wake up problem and I still do. The best thing you can do is not put the computer to sleep.
Something might be overheating and causing black screens and reboots. Can you monitor your temperatures with HWiNFO and report back, thanks.

It isnt't a temperature problem. Will post them up later on. However, the random reboots can pop up even after 2-3 mins after i started the PC, without any load on CPU or GPU.
