Hello guys! This is an issue I got until last month but I just want to hear a few different opinions. So when I wasn't gaming everything was fine. But when I played a demanding game then after 2 hours of gaming ( never less than that) the monitor would go black with no signal appearing on the screen and the only thing I could do was restarting by holding the power button. While the no signal monitor, the pc was still running but I could hear a freezing sound from the speakers. After some different opinions I concluded that my two year old psu ( a Force 750 W 30 Euros) was faulty so I decided to go with a superflower leadex 650 W platinum. I run OCCT for half a hour no problems found. Since then I haven't had this issue again ( but I play less time... I don't think I have played for more than 2 hours straight ). Was this the problem because this issue is quite common so I have seen other people saying cpu gpu or mobo.
My specs
Mobo : Asus M5A99FX PRO 2.0
CPU : AMD FX 6300
GPU : RADEON R9 270X

This issue is definitely GPU related but the PSU also plays a big role. If the PSU is bad or faulty thus providing "bad" power to the GPU, then stability issues will arise when you are stressing the GPU or playing games. Also a GPU that is overheating may have similar symptoms. So you have to make sure that the GPU temp is normal, the GPU cooling system is dust free and that fans are spinning freely. Also keep in mind that as a GPU gets older its thermal paste gets dry and it may need replacement.

That said I have a feeling that you have fixed the problem since your previous PSU was very very bad. In fact all Force PSUs are considered as "firecrackers" when stressed or get older. They are very cheap, their build quality is...

They are very cheap, their build quality is questionable, they cannot protect your system components in case of emergency and they should generally be avoided . You should consider yourself very lucky that you didn't end up with a fried GPU in your hands.

Hello panathas! I know that this brand is very bad and that's why I didn't even test the system to see what was causing the issue I just replaced the PSU... I was sure that this problem it's either psu or gpu but I think that if it was gpu I would have other issues like stuttering fps drop and bad resolution which was not the case. I thought also about the mobo due to two small bugs I have :
1) In bios and hwmonitor on case fan from 1200 rpm goes suddenly to 675000rpm for a second ( just the reading of course its not the actual rpm)and then back down and all over again
2) The boot device led is lit all the time ( also a bug I think since I don't have a problem with the SSD or HDD)
But since I knew my psu was bad I wanted to change it regardless. If there was still a problem wouldn't it have been shown on the half hour OCCT ?

Oh and I forgot to say that all cpu and gpu temps are normal I never really stress them to the limits and I always keep an eye on them.... and the case has no dust whatsoever

All those issues you are reporting are definitely motherboard related but have nothing to do with the GPU crashes. It seems that your mobo may have some minor hardware damage but fortunately it isn't too severe. Your mobo is old and such issues are common in older motherboards. I have 2 3+ year old boards that also have the abnormal RMP reporting, and one of those also reports abnormal temperatures in hwmonitor. Keep in mind that all those motherboard issues may be caused by a bad/faulty PSU that provides "bad" power to the motherboard and if you don't take action soon, permanent hardware damage may occur. After that you can't fix those issues just by getting a new (good) PSU. That said you can't be certain whether those mobo issues were caused by aged electronic components or your horrible previous PSU. Finally there is a chance that at least one of those issues is BIOS related. Try to update the BIOS but since this is a pretty old board you may already have the latest BIOS version.

The PSU is the most important system component that plays a big role in your system's stability and longevity. Getting a cheap one will cause you big headaches in the future. Fortunately you have learned your lesson. The Superflower PSU is a pretty good choice. Good luck.

EDIT. Your system seems stable but you need to stress it a little bit more for an hour or two, just in case.

Thank you so much panathas for your reply! I have one last question and i won't bother you anymore! I'm using hwmonitor and in package power I see a min 24.9 W and a max 49 W. Is this normal? Shouldn't it be near 100 W? I'm kind of freaked out! here is a screenshot: http://prntscr.com/h07dae

Do you have the latest hwmnonitor version; Your CPU is a 95W model but usually it stays well below that. Only by stress testing you'll be able to find the maximum power consumption but even that is a software estimation. I would't worry about that. Just monitor the temps and make sure that the CPU is able to reach its maximum clock speed. Also if you can't find a newer BIOS version for your board, you may do a CMOS/BIOS reset. It may fix some of your issues.
