Put together the following bits:- Asus A7V8X-X, AMD Athlon XP2400 (2GHz), 128MB PC2100 DDR, Gainward 128MB DDR AGP x8 Powerpack 660/TV out 2nd hand DVD, 2nd 48x Plextor CD Wtr drive Rear cooling case fan and Thermal soloution paste on CPU correct.
I can go in BIOS and set the settings all ok, CPU temp max of 55C and M/board at 28c with cut out for CPU at 95c.
After about 10 mins exit the bios and the computer will just all stop and cut out apart from the Motherboard still has power as green go light shows on M/baord and the front Case switch is still green showing power is also still on.
There are no spinning drives or fans though.
I haven't seen this problem before. Is it a Bad DDR memory, Faulty M/board, AGP Card or CPU ?
Suggestions on a postcard here in this post most desperatly welcome.
Hmmm, have you checke that all componts are seated correctly? also "I can go in BIOS and set the settings all ok, CPU temp max of 55C and M/board at 28c with cut out for CPU at 95c." gives a clue, it looks like the bios is doing exactly what you asked it to do. Daft question but apart from the thermal paste on the cpu you did also put a cooler on? Have you overclocked the cpu?
Sorry if I offended you, I know how hard it is to get a homemade pc up and running first go, have you tested the memory? but also still inclined to suspect either the cpu or the bios settings as per JOMI reply, have you also checked (with the case off) that the all the fans are running when you switch on? in particular the cpu?
