No Unibios. Wiring is OK i believe. The problem is on all 4 slots so I don't think its the contacts, but i cleaned them with a toothbrush and rubbing alcohol if it makes any difference.
But if the carts connectors are dirty it'll happen on all 4 slots..Cleaning with rubbing alcohol may not have any effect...believe me
I cleaned my mobo's connectors with the fine side of a cardboard nail file (gently)...The prong connectors need to be a golden-shiny brass color for a true clean connection...then I clean the connectors off(residue)with Contact Cleaner...Also can use toothbrush and 91 % rubbing alcohol..
Only would my mobos give me no problems after I did this type cleaning..
The carts: toothbrush and rubbing alcohol may have no effect..
Most of the problems are due to dirty cart connectors.
I open them and use (dry) Green or Red Scotch Brite to clean the connectors to a Golden shine then I use 91% alcohol to get off the dirt and residue.
You can use very fine grain sandpaper..
I've been using these methods for a long time..
They need to look like this..

Notice the small yellow part I missed on the connectors below..This is from a quick use of scotch brite..I haven't cleanned the dirt off yet using alcohol
