PSU went up in smoke. New PSU won't boot PC
So my 3 yr old Cooler Master 500W PSU went up in smoke today and I replaced it with a new 600 watt PSU.
I believe I have made all the connections properly and when I switch the system on, the PSU lights up, the fans work but there is no output on the monitor and even the keyboard doesn't work (pressing on CAPS key doesn't light up the LED). The green LED on the DVD RW stays lit but the tray doesn't come out
My specs are
1. Gigabyte 78LMT USB3 Mobo
2. AMD FX 4100 CPU
3. HD Radeon 5450 GPU
4. Crucial MX-100 250 Gig SSD
5. Seagate 500 GB HDD
6. Seagate 160 GB HDD
7. Corsair Vengeance 4Gig x 2 RAM
8. 600 Watt PSU (installed just today)
So far I have done the following.
1. Unplugged the cabinet and pressed the Power button for 1 min. Did nothing.
2. Took off the GPU and attached the monitor to the onboard graphics. Same results.
3. Removed the CMOS battery for over 5 mins and reattached it. Same results.
4. Removed the RAM sticks and tried one at Slots 1, 2 and 3. Same results.
5. Removed all the RAM sticks (with GPU still off the board) and powered on the system. No beeps.
6. Removed the SSD and tried attaching it externally to my laptop, but it wasn't detected. Could be a faulty SATA to USB connector. I bought it cheap from a local market.
Please advise what steps to follow next
Many thanks in advance
