A buddy of mine game me this Nvidia 9800GT he had laying around and i wanted to put in on the pc.
i installed it and everything the pc powered fine dint shut down or anything so im guessing it had enuff power to run it.
but the image is very distorted like really old bit format mixed up and stuff u can make out most of what u see is just not normal.
what i wanted to know is what could be causing this?
the card was dusty i dusted it out.
i used a dvi to dvi cable cuz i dint have a dvi to vga cable so i had to used a extra monitor i had that has a dvi plug. i used that same monitor to repair a pc yesterday so is not the monitor i think. letting windows update find and install drivers dint change anything.
the pc runs fine on integrated card wen i unpluged the 9800GT.
i havent really messed with it since i got the card tonight i just want your thoughts and get possible trouble shooting ideas ahead of time.
PC Specs
AMD Athlon X2 5400 Dual Core Proccesor
BIOSTAR MCP6P M2+ 6.X AM3/AM2+/AM2
4GB DDR2 ram
500GB Harddrive
Integrated Nvidia Geforce 6150SE
Antec Basiq BP350 350W ATX12V v2.01

putting a videocard on this machine wasnt a plan im doing it cuz the card is free
if is gona cost money like changing PSU and such is probably best if i wait till i can build a new rig lol

thanks in advance

I think your problem is, that you don't have enough power in your PSU.

 

[iPROTechman]

I agree also.

ohh ok i had that feeling to but is the first time i encounter this so wasnt sure. so u guys think is worth it if i go for a new PSU im sure i can find something for a good price since black friday is around the corner and i plan to use this pc for a while.

This is a good one: Newegg.com - CORSAIR CMPSU-650TX 650W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active PFC Compatible with Core i7 Power Supply

that does look nice but im on a tight budget. I really dont want to spend 89 bucks on a psu for this pc since the card wont be changed again if i can put it something cheaper that'll do the job that ill nice. as i staed above im only adding the card because it was given to me for free. wen i build a new one is gana be a good while b4 i do this pc will end up as either a storage unit or a server
i remeber i had a 500w psu on the gaming rig i sold i while back and was enuff to power the 9600GT it had.
here is a couple i found with good ratings

Newegg.com - Sunbeam PSU-H680-REV-US 680W ATX 12V 2.0 Power Supply - Power Supplies

Newegg.com - RAIDMAX HYBRID 2 RX-530SS 530W ATX12V V2.2/ EPS12V SLI Ready CrossFire Ready Modular LED Power Supply

Newegg.com - COOLER MASTER eXtreme Power Plus RS-500-PCAR-A3-US 500W ATX12V v2.3 Power Supply

this looks to good to be tru if is enuff to power it
Newegg.com - COOLER MASTER Elite 460 RS-460-PSAR-J3 460W ATX12V V2.31 Power Supply

I'd go with one of the Colmasters.... Or 6 bucks after rebate more.....
Newegg.com - CORSAIR Builder Series CX430 CMPSU-430CX 430W ATX12V Active PFC Power Supply

ThAT should easily do a 9800gt, and is a great quality psu.

ok so that corsair should do the job just want to be sure then ill order it tonight wen i get back from work.
34.99 with free shipping is nice.
god knows i wish i could build a new gaming rig trying to save up for a car or a motorcycle atm lol.

 

[patonb]

It should, a 9800 needs 450W and the corsair pumps out decent power.

I alwatys feel better if somjeone seconds my recommendations though.

 

[MindoverMaster]

Corairs are nice. Patonb's suggestion should work.
