Re: I have a problem please help
Unplug everything, then firmly replug everything back in (including the CPU) You've tried a different card, I am leaning towards bad mobo, but to ensure, basically rebuild the PC, no need to redo drivers and stuff though. last time I saw this it was in fact the CPU. Make sure to push down a lil on the CPU maybe a pin is bent as well.
Or try this, UN PLUG EVERYTHING you need the following
MOBO, RAM, some type of display wheater onboard video of GPU, and CPU, boot up PC if it fails then you know its those. It could be a bad part causing interference as well.
We had a PC today at the shop, we fixed the PC by pulling out the modem card. Similiar problem btu slightly different.
