Black screen problem at boot. Faulty PSU or another reason?

post #1 of 4
Thread Starter 
Hello. I have a complex problem right now. It will be a long story;

My Specs;
- ASUS M5A97 LE R2.O moba
- Gigabyte GTX 780 Windforce 3X OC
- AMD FX 8350 Black Edition
- 8 GB RAM
- Xiagmatek Tauro 500w Bronze 80+
- Cooler Master Seidon 120V Water Cooler for CPU

2 weeks ago, my bios started to show my CPU fan speed(Pump's 3 pin connector was connected to cpu fan on the moba) as 0 rpm at boot. After that CPU was overheating and my computer was closing itself. I fixed that problem with 2-3 times power cut-off from PSU everytime I open the computer.

Yesterday I cannot fixed that with power cut and tried to replace my water cooler with stock cpu fan. Everything was normal, after 30min of usage computer closed itself suddenly. There was no smoke or fried part on the motherboard, PSU, GPU or CPU after that. I tried to power on my computer back, but I'm seeing just black screen right now. CPU fan works, GPU fan works, led gives green light, everything seems normal frown.gif

I removed my bios battery for 1 hour, it didn't work. Tried resetting CMOS with jumper, but it didn't work too. Removed all of parts and connected them back to motherboard, but problem still exists...

I connected another GPU to my motherboard, still black screen. I connected my PSU(I don't have another PSU) and GPU to another motherboard, still black screen on that different rig.

I wonder if my problem is just with PSU. Is there any possibility that there are problem in my CPU, GPU or motherboard? If my PSU was faulty, could my rig's other parts be damaged? If my GPU or CPU was dead because of PSU, I'm dead too :/

Thanks If anyone can help me with that problem frown.gif

That PSU strikes me as being very low in quality. It also has a weak +12V capacity of only 384W, which means this is basically a cheap 400W PSU. I would bet that replacing the PSU with a good one would have the possibility of solving this problem. If not, then you'd at least have a good PSU that's safe to use for the future.

So could my PSU have damaged my CPU or GPU? Or everything is just because of PSU?

It's always possible, but I have no way to know.
