I am so gutted. I bought a HP G5225UK desk top system 2nd hand and the integrated graphics were working fine(although the guy i bought it from had to wiggle the VGA cable to get a picture when i first picked it up). I set it up and all was well.A week passed and i decided to put a dedicated card in to play better games. The day i came to do that i switched it on and there was no picture displayed on the screen. I tried a few different VGA cables but no joy. I saw that the power light switches onand it sounds like the hardrive is going but the screen says no signal detected check your cables and power supply. I have looked at the motherboard and can't see any signs that the VGA slot is damaged??Although the way it was intermittent when i picked it up makes me think it was faulty. So i ordered a 2nd hand Dedicated card (Radeon HD6570 2GB DDR3) It arrived this morning but without an installation disc. So i put it in the motherboard and again there is nothing the same on screen message on my smart tv (no signal detected). I have tried the HDMI slot and VGA. I have also tried different monitors. I am using Windows 8. My issues are these:
1. I cannot enter the bios menu because i can't see any images, does anyone have a answer?
2. Do I actually need an installation disc or should the board pickthe dedicated graphics up automatically?
3. Does my issue indicate a problem with my motherboard?
4. If it is a problem with the motherboard can you recommend a good replacement board?
Here are my system specifications
M2N68-LA (Narra6) motherboard AMD Athlon II X4 635
6GB Ram Integrated nVidia GeForce 6150SE (doesn't have a HDMI slot just the VGA) Computer case Mid Size ATX
Any assistance will be enormously appreciated. At the moment it is little more than junk!
