Hi all,

I'm hoping there's someone out there who can point me in the right direction to resolve this problem I have with my PC.

About 2 weeks ago I bought a new graphics card for my PC. I opened the case up and replaced the card but was shocked to find that my PC wouldn't power up and there was a deep buzzing/humming sound coming from the speakers. I tried the graphics card in another PC (in case it was the card that was preventing the power up some how) and it worked fine.

I thought that the mother board had given up, so I ordered a replacement mother board and went round my mates house. He connected the PC up to the power just for one last check, and lo-and-behold it powered up!!

I brought the PC home, reconnected everything and have been using the PC fine for the last fortnight.

Usually, I leave my PC switched on 24/7 but today had to shut it down because I had to have some work done on the house electrics. Now it won't power up and the strange buzzing/humming sound has returned. (Though this now appears to have stopped)

I've tried different things, disconnecting/reconnecting the switch to the mother board, leaving it disconnected from the power for a few hours but it still seems to be as dead as a door nail.

What do you guys think? Is this simply a dodgy power switch (the soft switch on the front of the case) or has the mobo given up somewhere along the line, or is it something that I haven't thought of (PSU??)

If it's the switch, any suggestions for a replacement?

Any help is much appreciated.

BTW, the PC is a Medion 808? (can't remember the last digit with an MD8088 motherboard).

Just been having a mooch around, would this work?

If it's not suitable, I guess I'll have to go for this one with an extension lead...
