Comp wont boot up

Connor.S · 04-13-2008, 06:41 AM

the only light on the key board is the num lock one. caps lock and scroll lock dont light up... and inside of mouse lights up. also the processor is brand new.

1. A bad PSU doesn't necessarily mean a killed mobo
2. A bad PSU can fry any other component too, for that matter
3. Even if it's obvious that SOME parts are getting power (e.g. HDs spin, KB lights turn on), it could still be a bad PSU
4. If the KB appears to get no power, it doesn't mean a bad mobo. It could be the PSU
5. Even if the HDs spin, the PSU could still be faulty.

I had the same kinda issue. I never figured out what was wrong with the comp, I only just totally disassembled it into as small bits as I could, blew the dust off the components (opened the PSU to handle it aswell), assembled the comp again and - huzzah - it worked. It worked even though I had previously double-checked every single cable... maybe I missed something? Oh, well.

I suppose ill try and take everything outta the case and reassemble. the PSU is brand new. after putting it in it worked fine for a day or two. now nothing. ive tried putting the old PSU back in, but the same problems occur..
