Ok recently i was having issues with my old rig, it was failing to boot most of the time. I figured it was probably a PSU or mobo issue, I needed an upgrade anyway so i decided to buy myself a bundle from a website. This is a link to the exact bundle I bought;
After getting my bundle my PC still failed to boot so I replaced the PSU with a new one, a Corsair 800w. This seemed to fix all my issues with regards to booting, or at least powering up my machine.
So this is where im at, when i turn my pc on all the lights and fans and components appear to power up, however I dont get any display from my gfx card whatsoever, its an AMD Radeon 4870 X2. I also dont get any beeps at all.
The mobo has onboard gfx and when i plug my monitor into this I do get a display and I am able to boot into windows and use the PC. I have tried the gfx card in both pci-e slots, it is correctly powered, but still no display. i have also booted without the gfx card in and i still get no beeps so I think i can rule it out for now.
I would believe it is either the CPU, mobo or ram, however the company i bought the bundle off explain that once they build the bundle for you, they overclock it and test it for a number of hours which makes me believe that they would know if these components were faulty.
Any help on what you guys think the problem could be is greatly appreciated. Sorry for the epic long post.
does the board have a speaker? most boards don't come with a case speaker bundled in. i had to buy one because my case didn't come with one. this would explain the no beep. as for the GFX card it is most likely no good. have you made sure to plug in the power plugs in to the GFX card?
if the board has a speaker it would look like a round black piece of plastic on the board. on inspection of pics of your board you do not have one built in. some where at the bottom of the board you will find a 4 pin connector that says speaker, spk or the like and you need one of these. http://www.newegg.com/Product/Product.aspx?Item=N82E168...
the end of this, the round part would be hard mounted to the board if it was built in. this gives the beeps.
if the GFX card is powered and is not giving a display the most likely cause is a bad card. I have had my bios set to use the on board VGA and still got display through a dedicated GPU so the chances of that setting being the issue is slim. Usually that setting would be in the chipset settings.
Ummmm....with a new Motherboard, you formatted the Hard drive and reinstalled Windows right ????? You have an "old rig" and therefore your windows install was replete with drivers for old chipsets and stuff that its trying to find while booting and they are not there. Sometimes it does work .... it rarely works well.
Does your case have a speaker ? Does your MoBo have a speaker or speaker connection ? I haven't seen one in quite a while, most enthusiast boards now use LEDs or diagnostic cards.
Also, one common mistake.... id the monitor OSD set to the correct input ?
