what could possibly be the problem?

shuarma · 04-10-2011, 11:50 AM

my computer wouldn't boot up, so i got a new mobo and cpu, and it STILL doesn't boot. the power supply is perfectly fine after testing it, everything seems to be connected properly. wtf?

How did you test the PSU? A standard multimeter isn't real useful in testing PSUs as they won't tell you how much ripple is in the outputs.

Make sure the RAM is hooked in REALLY firmly.

The Paper Clip trick can be invaluable at times such as this! While not as reliable as using the proper tools it can still be a helpful diagnostic step!

You can learn all about the Paper Clip trick in this handy PDF Guide!

Hope this helps!

Id suspect a RAM issue imo.

Test each RAM stick individually and in different DIMM slots if possible and make sure they are securely in place and properly seated.

Btw, what exactly do you mean by doesnt boot?

Do you mean the PC wont turn on at all, or the PC turns on but nothing shows up on the monitor? Make sure all PSU connections in the case are where they are supposed to be at on the motherboard, 20/4pin and 4/8pin 12v CPU connector.

The paper clip trick only turns on the power supply. It does not mean the power supply can provide the proper, clean power your computer needs. The Power_Good signal is not sent by the power supply until it can provide clean power.

when i say it doesnt boot i mean, when i hit the power switch on my case it does not turn on at all. the mobo LED is illuminated also. and i also tried turning it on by touching the power pins on the mobo with a screwdriver.

dead motherboard?

borg_7_of_9 · 04-10-2011, 07:30 PM

try the paper clip trick while the PSU is installed it may be a dead power switch circuit on the mobo..

This happened to someone else in these forum's they just left the paper clip in and use the PSU power switch to turn the PC on and off....(Till they get a new board)
