been a long time since I been on here, I have a MAJOR problem, around xmas time I decided to buy some new parts from a new supplier...Scan...as they seemed to have good things said about them on this forum. I bought: GA-790X-UD3P mother board ATI - radeon 4890 graphics card. Corsiar 80GB SSD I pulled some parts from my old system: AMD Phenom 9950 4GB of Geil ram DDR2-800 750W PSU with all the right connectors SATA DVD -RW and stuck in another 500Gb SATA hard drive Plugged everything in and...nothing...power came on and sweet FA, no display, no POST beep. did the usual fault finding, pull out parts, plugged in different ones, still nothing. pulled out parts and left them out and not even any POST error beeps. .....diagnosis: mother boards had it. set it back to Scan who set it back to me with a £25 bill saying its working! I then changed the CPU for an older CPU, just in case the BIOS didn't recognise it... still nothing. checked the psu, tried again still nothing. nothing nothing NOTHING!!! this is now driving me up the wall, I can't return it cos scan say its working and I have rung them recently and told me this....stop short of driving down to bolton from york with my system and SHOWING them its not working, I have not many options. so...for the love of god before i turn £500 of kit into scrap...please someone give me some advice!
