Tried to change the cable. It stopped blinking , this cable new cable is soooo old but it still works Thanks for all you help , ZanCrow

Alright....I think I was WRONG, it also blinks with my other PC...

I dont think the OS is the problem. I am trying to understand why the screen was working fine when it had the black border on the right side of the monitor and why it started to blink when I auto-adjusted it. ;/

Alright, I will try it with my older computer right now, but I really dont think that is the problem because it was working fine with my old computer, earlier

I already had the driver but it was old and I re-downloaded it. So, I think it was updated because it asked me to reboot and I did. However, the problem is still not solved.....The screen still keeps blinking. ZanCrow

Mhm....alright but how do you install GPU drivers? I have a R9 270x. I know im supposed to go on AMD but i dont really know where I find the downloads for GPU drivers ZanCrow

Hum.... this will be weird to say, but my problem got back already.....(=_=)"......sorry.... But now, I have additionnal information. When i changed my monitor back, there was this black border on the right side of my screen.... It looked like this : http://1.bp.blogspot.com/-IcrTDb-GP7g/T-l5L9M9C6I/AAAAAAAAB0o/vRJtXCdxcb0/s1600/DSCN1732.JPG (this is a picture found on google, but it looked like that on my screen too) A little time after, the "screen going black" problem came back. I thinks it is because my screen went on auto-resolution and it started to blink every 5-6 seconds like the first time....because the black border on right side of my screen disappeared. Thanks ZanCrow

Oh, I see, thanks Mine is a gigabyte one so i have to press Delete during POST right after PC is turned on. Also, I just changed the Syncmaster 2233 back on my PC and the problem stopped I guess this was just a plug problem ahaha......facepalm.... ()" Anyways, thank you VERY much for helping me with this. Can I ask you for another problem i have? It is a problem with Java. Thank You, ZanCrow

If you only want to play LoL and Hearthstone on max settings, I would recommend R9 270x. I have a R9 270x and i can play LoL with max settings + 70 fps. I also play Hearthstone and there is no lag. Plus, I dont overclock, so i think this could be a fitting video card for what you asked for. ZanCrow

I am not good with software aha..., can you explain me simple and fast how i get into BIOS, please? I know i did it once last year but i forgot ()". Also, i forgot to mention, but i changed into my really really old monitor and my screen does not go black anymore. I will plug back the Syncmaster 2233 to check if it was a plug problem. Thanks , Zancrow

Aha, I am sorry, its because no one replied to me after one hour so i thought no one would help me. ;/ My power supply is a rosewill green series rg-630 (http://www.newegg.com/Product/Product.aspx?Item=N82E16817182200&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=) and this my build, (it was built last year) : **CPU** | [AMD Athlon X4 760K 3.8GHz Quad-Core Processor] **CPU Cooler** | [Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler] **Motherboard** | [Gigabyte GA-F2A88XM-D3H Micro ATX FM2+ Motherboard] **Storage** | [seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive] **Video Card** | [Club 3D Radeon R9 270X 2GB '14Series Video Card] **Case** | [Cougar Solution (Black) ATX Mid Tower Case] **Power Supply** | [Rosewill Green 630W 80+ Certified ATX Power Supply] I was not doing anything before this happened. I just opened my PC like usual and noticed it was going black at every 6 seconds. ;\ If it helps, my monitor is a syncmaster 2233 : http://www.pcworld.com/product/53144/syncmaster-2233sw.html . Its a old monitor but it still works on my other old computer, so i dont understand why it doesnt work with this pc. I think it is a compability problem but I am not sure. Also, i use an adapter to connect my GPU to the monitor. Thanks for the reply and I will try to check this topic more often.

My monitor goes black for 1 second every 5-6 seconds, This problem never happened before. Do you guys have an idea on how to fix this? Thank you

I was able to go into safe mode. Now can you give me some easy steps on how to set it back to a time when i didnt have problem?

Its ben going for 2hours now....but now, it only shows 'we couldnt complete the changes, undoing changes, dont turn off the computer'

How do you go into safe mode? Also, could you explain me more in details, please?
