Sorry if this is going to be a bit long winded but I'll start from the start of this problem.
I recently brought two 1 gig ram sticks and put them in my pc, and I know this was a stupid thing to do and I don't know why I did it, flicked the 230volt to 110 volts switch on the psu causing a very satisfying sound after which my pc would not start.
I replaced the psu and fuses in the kettle cord and expected my pc to work fine after however when I turn it on now it doesn't boot to the bios page and there is just a black screen with a flashing line in the top left corner of the screen and I'm a bit lost of what's wrong and what can be done to fix it.
Thanks if you've read this far and I hope you can help me.
Oh and it's a dell dimension e5150 although the harddrive isn't the original one.
