Dead PC, any ideas???

[len_beach]

Right bear with me.

I've been running my old 1.7 with 640mb RAM for a couple of years. It's never skipped a beat but it is getting a little slow. A mate had a few old bits and pieces lying about from a 2.8 with 512 DDR so he passed them my way.

Anyway, I started by removing my motherboard and ancillaries, I fitted the new motherboard and hooked up my HDD's etc. When I turned the 2.8 on, everything fired up but there was no image getting through to the monitor. I checked and swapped cables, no issues there. After messing about for 30 min's I thought balls to it and put mine back together.

I got mine all back up and running, running through the log in and onto the desktop, then I thought why not try the 2.8 processor on my board.

I fitted the 2.8, it powered up, I logged in then I got a blue screen of death. I refitted my 1.7, it logged in etc. As it was loading up, I stood the machine upright again and began fitting the side panel. As I did this, the screen went blank again, as it did on the 2.8 initially. The hard drives only spin when you disconnect the IDE from the board.

I then checked every connection but to no avail. I left it over night but now the board won't even power up, even with a different power supply.

I am very confused. I remember Phill (he gave me the 2.8) saying he tried swapping the processor with this 2.8 and it gave him a BSOD but he sorted it after a while.

Could this processor have fried my mobo or is something else at work here?

Could be anything.. were you grounded when you were doing all this swapping of boards etc ?

I dont think the processor could have cause it unless there was something wrong with the processor itself (like a short).

I was for most of the time but when I was sliding the side panels back on, I wasn't.

I can't understand why both machines would now not boot up. I thought there may be an issue with my hard drive but it has never caused any issues in the past and it spins just fine as soon as you unplug the IDE cable.

Could be a conflict. Try re-installing Windows. Also try taking out and putting back in the battery on the motherboard

 

[len_beach]

I've tried the battery, re-seated the processor.

How would I go about re-installing windows if I can't get the machine to boot?

Is the motherboard shorting out on the case?

Remove all non essential components and boot it (one hard disk, one stick of Ram etc).

If all else fails, lay everything out on cardboard and boot it up out of the case....

 

[len_beach]

I've just remembered on the subject of shorting. At one point last night, if I tweaked the motherboard a little along with the graphics card, the power would drop off, if I did it again, it would come back on.

Could tie in with your theory DutchRS.

Any luck?

i know CPR

Also what make motherboard?

Len you loser.:clown:
Its the Power supply, your 1.7 psu won't power that board sufficiently. It doesn't have a P4 connector anyway, you need to use the one out of the case I gave you.
I'll come round and assist.
You stick to the cars mate, which reminds me, where are my springs and what about my cambelt kit?
