Hello,

I desperately need help. I have installed a new PSU and GPU into my older Dell computer. It was working w/o any problems for three weeks. (under heavy load). Then last night, in the middle of my game it just studdered and everything went black. The monitor was on, but was not receiving a signal anymore. The PC was on, fans were moving, but looked like HD and graphics card were just dead. I was able to reboot it, but it shut down again almost immediately. I have no idea what this could be. Here are my specs.

Dell XPS 8500 Desktop
COUGAR VTX500 500W ATX12V 80 PLUS BRONZE Certified Power Supply
Intel Core 3rd Gen i5-3450 Processor (3.10 GHz with Turbo Boost 2.0 up to 3.50 GHz)
8GB, DDR3 UDIMM Memory, 1600MHz, Non-ECC (2 DIMMs)
Dell Wireless 1703 802.11b/g/n, Bluetooth v4.0
1 TB 7200RPM SATA 3.0Gb/s Hard Drive
MSI Radeon RX 580 DirectX 12 RX 580 GAMING X 8G 8GB 256-Bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card
16X DVD +/- RW Drive
19:1 media card reader
Windows 10
Connected things: Keyboard, Mouse, Speakers, T-Flight HOTAS, Printer

I would really appreciate someone's help in trouble shooting this. I'm not super computer savvy but I know enough to be dangerous.

Thanks in advance for the assistance. I don't even know where to begin in trouble shooting this.

Thank you blackbird. I'm going to get the SeaSonic - S12II 620W 80+ Bronze Certified ATX Power Supply. I don't need the modular one. Got plenty of room to store the extra cabling.

I will report back after I install it. I really really hope this solves the problem. :) Thanks for the quickness of the replies.

Sadly, replacing the power supply made no difference. The unit boots, posts, then when windows loads it gets to a certain point, and the video shuts down. No Signal. I'm starting to think the graphics card might be bad, but I don't have a working one to test and there are no on-board graphics to test with. :( What do you suggest?

UPDATE: Installed an old graphics card (unfortunately no hdmi plug) but it's displaying ok. So, could the new graphics card have just died after three weeks of use?

Anyone have any thoughts on this?
