Bought a Adaptec SCSI 19160 card, noticed performance was really bad and saw a couple of ic legs were pushed together. Contacted the seller (on eBay) and he send me another one. Seems it's a 29160 this time.
So, installed it and reinstalled Windows 2000. All ok, it was twice as fast as the 19160. After installing some Windows updates the system asked for a reboot. Still fine, did a couple of more reboots. Then, installed GPU drivers and rebooted again.
Now the Adaptec card doesn't display it's BIOS anymore on booting and I can't get into it's configure screen anymore. Tried the card in my modern PC, same issue.
Took it out couple of times and sometimes got the blinking DOS cursor and both PC's then freeze.
Now, I discovered when I push the card down while it's installed, it gets detected 100% of the time. I only need to push it down until the card's BIOS is on screen. After the HDD detecting I can let go and the card functions fine.
This is obviously annoying, any way to check what's the cause? It has a BGA chip which gets a little warm, pushing that one won't fix it, also pressed a bit on the bios chip but that doesn't work either I think.
So it only has issues with initializing it's BIOS, any ideas? I don't see any scratches or other damage, it looks brand new actually. If required I will post some photographs here.
EDIT: I should add that regardless of bending the card it always get's an IRQ and is seen by the PC's BIOS. Only issue is the SCSI BIOS thats not working unless bending/pushing down the card. I also tried different PCI slots and I've cleaned the PCI connector of the card.
