Radeon 850xt upgrade, computer wont boot.

[XCLAN]

I bought a new case, power supply, DVD burner, and Radeon 850xt.

Installed everything and the computer wouldnt boot, wont even post or make a beep. after a dozen tries I unhooked everything except motherboard, cpu, ram, video card, power supply and still not boot, beep or post. However all the drives spin up, the fans, everything starts when connected i just dont get the beep when you boot and The computer wont post.
Finally I put my geforce 4 ti4200 in and the computer works. Am I lacking power from my powersupply? yes the card was plugged into the molex connector and I tried a dozen different molexes, even ones on their own strand, with nothing else connected. I tried another 420 watt power supply from my previous computer wich has always worked and get the saem results. The new power supply I have is 430 watt thermaltake.

k7vta3
athlon sumthin cant recall....its an older 3200 or sumthin...lol

That can happen with not enough power. I had it happen last month on a client's machine. She had a Radeon 7200. It worked perfectly, albeit a little slow. So, I put in a Radeon 8500. Windows would stall on loading. Put the 7200 back in - and it loaded sin problema.

She needs a bigger PSU, but it is not worth it for her old K7M mobo. Time for a new machine in her case.

I remembered I bulit new motherboard that have AGP 4x and the new card is 8x it did not boot at all so I put 4x card it works just fine.

I had a similar problem with my 850pro and I just kept playing with it and reseating it until it worked

Hmm...could be the PSU I have that same exact vid card and thought it was a little clunky with my 500 watter..so I upgraded to OCZ 700 watt Gamer PSU and now it working great. Nice hearing from ya again and good luck with that setup.

Thanx for the info Daryl, and everyone else. I guess I will just order a 650+ power supply

 

[XCLAN]

well the 650 watt power supply didnt help. same results. maybe its my k7vta3 cant run the radeon x850? due to my mobo only being 4x agp?

damn, sucks that i just read this post because i could have told you it wasn't the psu...

to ask a stupid question, you are connecting the video card directly to the psu right? (although, if you weren't, i think that would cause a long continuous beep)

is the video card brand new? or did you buy it off of ebay?

 

[XCLAN]

I connected it straight to the power supply and it is brand new from ATI.com

 

[ockky]

update the motherboard maybe /shrug?

 

[lyssword]

Is it possible u got a bad vid card? RMA then/return it.. Unless u can prove that 850xt works on another comp or something

Just for the record It was my mobo i found a few other people that couldnt get this card and other 8x agp cards to run on my motherboard, I installed it in my old p4 mobo and ran it a few hours, ended up ordering a new mobo, athlon x2 4200+, and 2 gigs corsair.

I sold this card tonight and am in the market for a PCI-E vid card.

No more ECS for me ever, I always end up havin problems later down the road. All to save 30$ up fron, and eventually have to replace it anyways.
