Hi,
my problem started with USB ports not working properly in front panel of my PC. When I was using external SDD connected to one of these ports (either USB 2.0 or 3.0) it worked just sometimes, speed of transfer varied and when I checked the disk using a program that scans surface, there were CRC errors... I even replaced the external case for the 2,5'' SSD, but I figured out later that the disk and the external case were absolutely fine when I plugged it to any USB port available at back of my PC and there were no CRC errors.
I have motherboard MSI B75MA-P45 and PSU Elementum E2 Sl-450, I bought this computer from someone a year ago and it was already used I think about 2 years. I plugged the connector for USBs of front panel to JUSB2 instead of JUSB1 on my mainboard, but the problem was still there. I cleaned the computer form dust (also inside PSU) and it didn't help. I checked voltages in BIOS and they look fine, for example voltage +12 V is about 11,85 V. However right now in HWMonitor (I'm using Windows 10) you can see that voltage +12 V is only about 8,2 V. Voltage +5V seems to be too high, it is +5,6 V. See screenshot:
Also a strange thing I discovered when cleaning my PSU from dust (see below). I am not familiar much with electronics... is it normal thing - that white something that looks like congealed glue in there ?!
