Hey there, I'll keep it short and sweet.
Basically a few days ago I upgraded my memory and all was working well until I turned my graphics settings up in WoW and the textures turned to a psychedelic muddle! When I turned the graphics down I got a BSOD and when I rebooted I was plagued with web crashes/inability to open programs. I narrowed this down to bad ram (And i was right after memtesting the sticks last night) so I decided to try the old sticks again.

Here's the real problem..

After reinstalling the old sticks I could now only boot to the splash screen before getting a quick BSOD and restart, I'm unable to disable automatic restart either by pressing f8.
I've tried with each stick of ram, no change - and they passed a 12hr memtest last night.
This morning my replacements came and I decided to pop them in - No change.

I have no clue what to do next and urgently need that pc back. Cheers!

Try a single RAM stick in a different slot.

It may or may not be pert of your issue but that PSI is poor quality and underpowered for the GPU.
Did you run MemTest on one stick at a time?
Remove all the RAM, clear the CMOS and install one stick of the old RAM.

Hey, thanks for your speedy replies.
I had no idea my PSU was underpowered, cheers for that. I don't use my system for "intense" gaming anyway and was probably upgrading soon.

I have already tried with each stick of my old DDR ram in different slots however did not clear cmos. I'll clear and try again, also trying each stick of the new ram in different slots.
I didn't memtest one stick at a time, no. I also have already sent back the defective pair of RAM so are unable to test them.

Did you want me to memtest each individual stick of old DDR? They passed together on 10+passes.

Hey. I cleared CMOS and tried with a single old stick - no change. Also cleared again and tried with a stick of new ram out of curiosity, and still no luck.

What next ?

Remove all the RAM and boot. Listen for beep codes from the Mobo speaker. No RAM & no beeps indicates a Mobo issue. If you get the proper beeps, I would suggest a bench test.
Remove EVERYTHING from the case.
Set the motherboard on a non conductive surface. The motherboard box is perfect for this. DO NOT PLACE THE MOTHERBOARD ON THE STATIC BAG! It can actually conduct electricity!
Install the CPU and heat sink.
Install 1 stick of RAM.
Install the video card and attach the power supply connection(s) to the card if your card needs it.
Connect the monitor to the video card.
Connect the power supply to the motherboard with both the 24pin main ATX Power connection and the separate 4 or 8 pin power connection.
Connect power to the power supply.
Do NOT connect ANYTHING else. Make sure you have the power connector on the CPU fan connected.
Use a small screwdriver to momentarily short the power switch connector on the motherboard. Consult your motherboard manual to find which two pins connect to your case's power switch. Then touch both pins with a screwdriver to complete the circuit and boot the system.

If all is well, it should power up and you should get a display. Then assemble the parts into the case and try again. If the system now fails to boot, you have a short in the case and need to recheck your motherboard standoffs.

If the system does not boot after this process, then you most likely have a faulty component. You'll need to swap parts, start with the power supply, until you determine what is defective.
