Hi. Just over a week ago our power went down in our front room (which is were the PC is). I checked and found that the fuse for that room only had tripped. So, switched it back on. After about 5 minutes there was a loud bang and everything went dead again. It turns out that the power supply in the PC had blown. however, the machine wasn't switched on. The PSU was on, but not the machine itself (not sure if this makes a difference to the diagnostics?). I plugged an old PSU in, but the second I switched that on it sparked and died. Now, both the PSU's were old, over 5 years. However, the replacement I ordered worked initially until I was screwing the hard drive in place (it only had one screw for some reason, so decided to put a second one in), got a spark and it died - the PC was switched off (I'm not that stupid....) but the PSU was on (so maybe I am that stupid...). Checked the PSU in my old machine and still didn't work, so sent it back from whence it came.
Now, I would surmise that me messing about with the screws caused a short and blew the power supply (oh, the mains didn't go off at this point, just the PSU). But, would that have damaged anything in the machine which would then cause a PSU to blow again?
The replacement arrived this morning, plugged it into the old machine (which is just motherboard, CPU and sound card - no onboard graphics etc) and the motherboard LED came on, so I knew the PSU was at least working although I didn't power up the machine. Plugged it all back into the main machine, switched it on and it instantly blew and tripped the switch.
I initially thought it could have been the power cord, but I used a different one for each replacement (the initial new PSU blew the plugs fuse when it blew itself) so not sure if that has caused it.
I am going to get another replacement, but I am unsure what's causing the blowouts and I don't really want to blow another PSU. Ebuyer may accept a second faulty return - but a third....?
As far as I can tell it must be one of the following:
Dodgy PSU's (assuming that the initial issue was simply due to age etc)
Something is knackered in the machine and causing the blow outs (motherboard, Graphics????)
An issue with the house electrics.
I should also add that the PC is connected to an extension lead with a build in circuit breaker/tripper thing but nothing suggests this has noticed an issue. I have two, and each blow out was plugged into a separate extension lead.
The new PSU was a 500w unit, as was the previous PSU which had lasted a good many years, so I doubt it's that. However, just in case here is my system:
AMD 64 2.4ghz (not that I have been able to get it above 1.6ghz!!!)
Creative Audigy2 Z sound card
Radeon 16500 graphics card feeding a HD TV (VGA) and a 19inch monitor (dvi)
2x SATA HDD - 500gb & 750gb
1x DVD RW Drive
Plethora of usb connected devices but all powered via a exteral powered hub
I have had a quick llok at other issues with blow-outs on this forum but couldn't see anything which would help here. Iit could be an overload on the circuit board to the house i suppose, but in between the initial blow and todays we replaced a Netgear Wifi and seperate VM Modem with a VM wireless hub - which I assume would cosume less power as it's one device replacing two???
Thanks in advance for any help people can provide. I've tried to be as descriptive as possible above, but if anything needs clarifying or you need further details just ask. Thanks.
