thanks, in other news, the issue appears to have resolved itself, ive plugged everything back in, applied some thermal paste to the new gpu, which is now idling at a steady 57 degrees, which i thought was acceptable. also one thought, when i got the card, i manually increased the fan rpm with overclocking software, could this have drawn too much power from my not great PSU and caused the system to fail?
okay new problem, i got the system booted, everything working fine, all good, then i installed the graphics drivers and all of a sudden my machine is really laggy, crashy and slow??
