Hello, im currently running an ECS HT2000 Geforce6100 SM-S V1.0, with an Amd dual core, at 2.0 . I have 4 gigs off ddr 2, and a geforce 7800 gt video card.
as you can see some off my parts are fairly old, i purchased a new video card, a geforce gts 450, the guy at frys said i would need a new power supply, mine currently at 350, i bought a thermaltake TR2 430w
Everything was working fine, i just wanted to upgrade my video card. Yesterday i took out my old card and power supply, connected all power cords to the new power supply, and put in my new card but system just beeps, it wont boot up. so i put back my old video card, still no change, then i put back my old power supply again no change. So now everythings back to how it was before i replaced the parts, but my comp wont turn on. when i push power it just beeps, black screen. i went thru n made sure all connectons were complete, and i only have the power n video card connected in the back.
Can anyone offer any advice? i dont wanna go to geek squad, but iono what i did wrong. :/
