I recieved my new computer yesterday and everything worked fine, but when I got home from work I tried to run World of Warcraft, and all of a sudden my XFX 5870 stopped outputting any video. I've tried turning off the power supply for a while, pressing the clear CMOS-button, unplugging my USB-devices and connecting my 40" Samsung LCD TV with a HDMI-DVI cable. The TV won't show any video either.
Here are my hardware (I'm running Windows 7, 64bit Home Premium by the way):
- Chieftec Super Series 750W
- ASUS Crosshair IV Formula
- AMD Phenom II X6 1090T Black Edition
- CoolIT Systems ECO A.L.C. CPU Cooler
- Kingston DDR3 HyperX 1333MHz 2GB CL7-7-7-20 (x2)
- XFX Radeon HD 5870 1GB (My Samsung 22" LCD Monitor is connected to the GPU with a DVI cable)
- Sony NEC Optiarc AD-5240S
- Samsung SpinPoint F3 1TB SATA2 32MB 7200RPM (x2)
- Corsair SSD Performance P64
The GPU fan is actually running, but I'm picking up no video signals.
I did also check to see if the memory modules were supported by the motherboard, but they weren't listed. Can that have anything to do with it? Some people have told me that the power supply could be the culprit, but there should be plenty of wattage to supply the system. They also indicated that the XFX 5870 might be having trouble if the PSU is a little off with the voltage or something like that.
I simply have no idea what to do.
Will try to provide more information on request
my pc stopped displaying " video signal " and i got it tested and it ended up being the graphics card so try onboard if you have it, and also try a different possibly slightly more powerfull PSU as that is the most cause for black screens on pc.
my friend recently had booting problems on his new build and it ended up being his brand new PSU was faulty.
Yeah, I guess I have to send it back. A few more weeks to go with a borrowed, 3-year-old Dell computer
I found out that the company that built the PC had put a cable in between the mobo and the GPU, so that it wasn't completely fitted into the slot, which may or may not be the cause of this whole thing.
