Hello guys. First, English is not my primary language sorry about that.
Issue: When i run my computer, after a while like 30 mins or 1 hour (i guess depends system load) i get some very complicated symptoms. Well i just test voltages; after 5 minutes i run my computer, 5V goes lower like, 4.95 ... 10 mins later 4.89... and 30 mins later its goes too low like 4.40 etc and finaly it drops like 4.10 and symptoms came around. Well i just downloaded dataSheet, you can find here;
I check the page 33 (about voltage place) ... I saw there is 5V output from PQ14 (FDS8884). So i checked voltages on PQ14, input pins of 5.07 volt is always good there( wich is input of PQ14 (+5VPCU) , (so i guess thats means ISL6237 regulator is working fine...) But the output pin of PQ14 wich is +5V goes out there is not good... starting going down couple mins later of my computer run... So i just tried to replace two parts: PQ14 and there is little capacitor at the PQ14 ( PC63 -1u/25V). But problem is still same. Is there anyone help me about to find out, why this 5v goes down every minute like 3% or someting? Thank you!
