please help me with my problem with video cards for my hp pavilion slimline s5640kr(stock psu, hp 2701c0) desktop. i have 4 gpus:
A - gt635(ddr3, 64bit, 1gb)
B - 8300gs(ddr2, 64bit, 256mb)
C - radeon hd 7000(ddr3, 64bit, 1gb, black fan)
D - radeon hd 7000(ddr3, 64bit, 1gb, red fan)
A was my main gpu and B was a backup. after a thunderstorm and brief blackout, A would no longer work so i have been using B. washing and multiple tries to heat gun A did not fix it. rarely will it give a signal when i boot and most of the time it will give a black screen as the fan spins and the computer continues to load windows. when A does work, it will turn off on its own at any time. i was able to get into windows with A and got cpu-z details but the computer read it as a basic display device, not a gpu with a name and brand. A's other details would not show up either. Then it died.
i bought C as a replacement for A since the specs were identical or close to each other. the seller did not have a machine for testing but it had a low price so i went for it. it did not work. i showed videos of C and the black screen and later B with windows just to prove that my desktop was not broken. we tried to troubleshoot it to no avail. we agreed that it was defective so i was refunded.
i bought D hoping that it would work and this time the seller showed me a video of the gpu working before i paid and had it shipped to my address. when i got it, black screen and fan spinning.
A, C, and D will give a black screen, the fan will spin, and you will see the hard drive light and blink as the computer proceeds to windows.
i've removed the cmos battery on the mobo hoping that it would help. no. i've also formatted my hard drive and reinstalled windows to no luck.
now i'm not sure what the problem is and why ddr3 gpus will no longer work on my computer. can the power supply be insufficient to power ddr3 gpus but not my ddr2 gpu? is the gpu slot damaged? i can't say yes or no to any of them because as ddr2 gpu still works and the others won't. i looked for a downloadable bios for my mobo, there isn't and hp's update service says that my machine is up to date.
i just want one of the ddr3 gpus to work.
help please.
