Hi, I am having an issue with my brand new system. After i installed everything I booted up the pc and it seems like it is working since the fans and lights are all on. Unfortunately, I do not get anything on screen, not even the bios startup. I have replaced my motherboard twice from an asus m5a97 le r2.0 to a msi 970a-g46. Also, I have replaced my geforce 9800 gtx performance edition to a hd 7770 to try and fiz this issue. My current setup is the following:

mobo: msi 970a-g46
Processor: AMD 8350 4.0 GHZ
Ram: Patriot 1600 2x8 gb
Power: 800W Rocketfish
Video Card: Asus HD 7770 2gb
Hard Drive: Hitachi 400gb


PS: Before I bought this new setup I was having the same issue but it would at least start up sometimes. Could it be the Hard Drive? Can the hard drive cause the system not to boot not even to the bios? Thanks!!

You have the monitor connected to the GPU correct?

Have you tested the RAM?

Yes I have. I am using the dvi/vga converter.

I have also tested the memory ram by using one at a time and both times happened the same. It should not be the problem unless both rams are bad. The only things from my old system that I am using here are the psu and the hd. This issue showed up sometimes with the old system but after restarting it many times, about 30, it would work again. That is why i was thinking that the hd could be the failure but I do not know if it is enough not to have the screen turn on.

It would still get to the BIOS with no HDD. The PSU could be bad. Its from a very low quality manufacturer and has a high likely-hood of failing.

But everything lights up. If it was bad wouldn't it not even be able to power up anything? I mean it is not as if it was going from a 800w to a 400w. It should work or not correct?

Its a poor quality PSU and it likely only makes around 400w. If it was running your old computer it could be ok, but I would guess its dead. Its a crap PSU.

Get a 500w from Antec, XFX, Corsair, Seasonic.
