Hello (:
I have some kind of weird problem with a black screen when turning on my computer
When i turn off/on the computer or restart it the monitor remains black and have no signal ? I have to turn off the computer and on again sometimes i have to do this over and over untill the monitor gets a signal and sometimes it works again after 1 restart.. There is HDMI In it also but it seems to have the same problem no matter wich connection i use.. Please help me

The grafic card is a ATI Radoen HD 4600 series

have you tried reseating your GPU, sometimes the pins dont touch the PCI slot because it was moved due to weight or by bumping the comp case.

btw can you post your entire spec.
perhaps this is a PSU issue.

when you say no signal in monitor, does that mean just no signal in monitor and you can see activity on harddisk ?
i mean can you tell that pc itself is working (loading windows, bios beeps and stuff) but you just cant see the display ?
If you have DVI connector handy, try it.

Well yes it Makes noice and i can hear when Windows loads up from the starting sound thing But the monitor doesn't seem to get any signal s: Using the blue Cabel thing on the monitor and HDMI isn't working either then there is a white cabel connection i don't know what the differents of those 2 are

what's your PSU? is this a custom built PC or not? I'm thinking that the one you are currently using is a generic PSU and it's not supplying enough power to your rig...

okay, try one thing. Next time when this problem appears, take out monitor's connection wire from Pci-express gpu and try plugging it into your BUILTIN vga.
I think for some reason your motherboard is routing video signals to your builtin graphics card over your pci-express video card. if you see display in your builtin video card, try reseating you Pci-express graphics card AND goto your bios, make sure that video source is prioritized for your Pci-express video card.
you will have to browse a little in your bios to see that option, its always there.

good luck!

(facepalm) lol

syliviex · 08-06-2012, 13:06 | posts: 15

yes there is but i don't know if the onboard is the one sealed in the buttom ?

syliviex · 08-06-2012, 13:12 | posts: 15

Yes it was sealed in the buttom d:
So next time i turn off my computer and it goes black i should try plugging it in that instead of the Grapic card ?

yep .. lol

see the blue thingy on the top left ? thats your builtin VGA port.

syliviex · 08-06-2012, 13:21 | posts: 15

Thank you very much d: So if the monitor display comes up after i've plugged it in builtin VGA its because The grapic card and onboard is in conflict ?
Sorry for all the questions but feeling a bit stupid hehe d:

umm.. that happend to me when i was installing my new 7970 lol

I had to reset my bios to fix this issue, may be this method is a little advanced for you.
you can try reseating your graphics card in pci-express slot. replug graphics card power (if it requires external power). check your bios and make sure first display adapter or something like that option has Pci-express selected.
this should fix your issue. (:
