[HELP] No Signal from Monitor

[xenova]

Hey everyone,

I recently bought a PC from IBUYPOWER and received it today. I turn it on and I get no signal from my monitor. Here are some steps I have taken:



1) Ensured that everything is plugged in correctly

2) Taken out the GPU and re-inserting it

3) Tested the monitor with my old PC and it worked fine

Neither step 1 nor 2 helped. I also noticed that the GPU's fan is not running when the pc is on. I think there may be an issue with the connectivity between the GPU and motherboard?

my specs are as follows:

1 x Case NZXT Phantom 410 Gaming Case - White

1 x Processor Intel® Core™ i5-3570K Processor (4x 3.40GHz/6MB L3 Cache) - Intel Core i5-3570K

1 x Processor Cooling Liquid CPU Cooling System [SOCKET-1155] - ARC Silent High Performance Fan Upgrade

1 x Memory 8 GB [4 GB X2] DDR3-1600 Memory Module - G.Skill Ripjaws X

1 x Video Card AMD Radeon HD 7870 - 2GB - Single Card

1 x Video Card Brand Major Brand Powered by AMD or NVIDIA

1 x Motherboard ASUS P8Z77-V LX


1 x Power Supply 650 Watt -- NZXT HALE82N-SI / 80+ Bronze

1 x Primary Hard Drive 1 TB HARD DRIVE -- 32M Cache, 7200 RPM, 6.0Gb/s - Single Drive


I would really appreciate it if anyone can offer me some help.

Plug your monitor into the on board vga and see if it works there, if i does then you may need to alter the settings in the bios to use the hd 7870. Another thing to try is removing the hd 7870 and re seating it in the pci-e slot, it may have been dislodged in transit.

Does the system boot?

If it has a case (system) speaker, do you get any beeps?

Does the PSU fan run when you turn on the PC?

Are the PCIe cables from the PSU plugged into the video card?

Work systematically through our standard checklist and troubleshooting thread:

I mean work through, not just read over it. We spent a lot of time on this. It should find most of the problems.
