Hello,

when i check the PSU with voltmeter it shows 24 v, 6.5v and 10v for the readings of 12v, 3.3v and 5v which is double the amount of normal set of readings.

Whether It shows PSU is completely faulty and it will break the motherboard?
Initially i did not hear beeps without RAM also i try to clear the cmos several time but no use.. so i try to check the PSU but with wrong readings..

Any ideas?

Thanks and Regards

See if the PS is switchable? There may be a little switch in back to change the operating voltages.

Hello Mark,

No there is not switch on the backside of the PSU.

I measure the volt in VAC instead of VDC that is the issue, now it shows 3.4v, 5.2v and 12.2v is it ok?

Therefore the PSU is good? May be the issue lies with Motherboard?

Regards
