Post by: Team 9 on May 28, 2012, 02:06:48 PM: is there any way to check the BIOS? if so, then do some c on it, if not, locate the BIOS chip (marked on the motherboard) and check if it's damaged or dislodged.

it looks like this:(https://encrypted-tbn1.google.com/images?q=tbn:ANd9GcRhrm39yH_NHjcPUeWKsiD0pVTuzdfkt2Q7CpSCZnqnAL6Mu_xCoA)

alternatively, look for the CMOS (complimentary metal-oxide semiconductor) it's a silver, dome shaoed component on one of the internal boards, check for damage or dislocation, and try to replace it

look for any loose or damaged wires, connections or solder and attempt to replace/repair it

I'm going to guess this is either the motherboard being dead or the power supply... Not sure about the second, but the first is very likely possible.

I'm not sure why it died. It always ran well, and never got above 70 degrees, rarely above 50.

If not.. Well, better find out what is broken in there. And if you're in the need of getting a new PC in the end... Be sure to get the HDD out of the old one.

Post by: Badger on May 28, 2012, 03:48:09 PM: Yeah, still got warranty, I only got the damn thing at Christmas. Is there anything else to check out?

Post by: powerrave on May 29, 2012, 12:16:20 PM: Not that I can think of, given the situation. Think you'd be best of using that warranty.
