Does anybody have a clue what is going on here, any help appreciated as I am pulling my hair out!
I have a self-built PC based on a DFI Lanparty 875Pro, P4 CPU. The gfx card is a HIS Excalibur 9800 128 AGP. I have had this rig for over a year.
Today I got a new HIS X800 Pro 256. The PC was in use and working fine when I got home. I shut it down, took out the old card and fitted the new one. The PC would not post when turned on, no vid signal or anything. I checked the agp seating, molex lead, and other cables that might have been dislodged, apart from 1 ATA cable that was a bit skewed it all looked fine. I put it down to bad luck, got an incompatible card or a dud maybe.
So I put the old card back in. Same result, no post, no vid signal. I’ve tried putting in an old Geforce 3 and that doesn’t post either.
The only 2 conclusions I can come to are:
a) the new card was faulty and did some damage to the mobo. I suppose it must be feasible but could a faulty card really do any damage like this?
b) Something has been disconnected/damaged in the card changeover procedure that stops the mobo posting. But I can’t see anything.
The diagnostic leds on the 875 are showing 0111 with the HIS cards fitted which is supposedly ‘final initialisation’. They show 1111 for the G3, which is supposedly ‘booting’ except it’s not.
The monitor is OK, tested on laptop output.
Have cleared CMOS.
Tried disconnecting other molex’s in case to make sure more power going to cards.
Out of ideas now.
If I get a new mobo and the 9800 works in it I am not keen on retrying the X800 in case the same thing happens.
