I need some help!
I have an old system I built in 2010 with the following components:
- Corsair TX Series 750W power supply - thought that was the problem so got a new one from Corsair (still under warranty!)
- Gigabyte GA-MA790X-UD4P AM3/AM2+/AM2 AMD - thought that was the problem next, so bought a replacement on eBay (from China as it is not commercialized in the US anymore)
- AMD Athlon 64 X2 7750 Kuma 2.7GHz Socket AM2+ 95W Dual-Core
Is it safe to say my CPU is fried? What else could be wrong?
- 2x G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066
So everything has been replaced but the CPU and DDRAM. I unplugged everything, only left the CPU and motherboard connected and even then does start.
Please help me with these two questions, would be much appreciated!
1) Is the CPU fried? Could it be something else? When the system does turn on, the CPU works fine...
2) I really don't want to have to buy an old CPU as well that fits the motherboard as I was hoping to ditch my desktop for a laptop but I have 5 HDDs in Raid 5 with all my personal pictures etc.
If I ditch the system now, how do I get access to the 5 HDD in Raid?
Thanks for your help

The motherboard should be healthy as it has just been replaced with refurbished version from reliable Chinese store.
When the system boots, it runs ok. But as soon as I turn it off it doesn't restart. I inspected the power switch cables, no sign of wear and tear which could create a short. Initially the case fan would start turning for about 1/2 second, then stop, which made me think there was a short somewhere. Having now replaced the CPU and motherboard, I don't know what is going on.
Any thoughts / suggestions much appreciated

should work. Or could go to a local computer shop to get one.
If the computers are on the same network, you can remote in or view user accounts or anything set for shared access. Just make sure remote access is enabled for both machines. I move files around between 2 laptops and 2 desktops this way.

Received the new power switch. As I tried to install it it exploded in my hand - clearly not glued or assembled properly (I was careful!). Are the power and reset cables/buttons interchangeable? I now have a replacement reset button but the power switch is in pieces and I'm not sure I can reassemble it.
Thanks

I would RMA it back to where you bought it. It shouldn't come apart like that. If you got it at newegg, they are usually really good about these type of things.

I will definitely RMA it. I was able to borrow the power switch from a friend's computer. My computer still does not turn on (2 times on about 15 attempts after unplugging the power cord from the PSU each time). I have only the Mobo and CPU connnected - removed the RAM and cards.
Is it the CPU that needs to go at this point? I don't want to invest anymore in this tired old machine...!

Hi
Thanks for the continued help... I tried a new power switch, outside the case, triple checking the connections, and it still only turns on once in 20 attempts, if not more.
I do not know if the new motherboard works fine - but how would I know at this point?
I am not sure I want to invest more in the computer and replace the CPU if that is the problem (what else could it be?).
I am considering ditching that old desktop but the problem is that I have all my data on 4 1TB Samsung drives in a RAID 5 array.
If I bought a laptop, what would be the cheapest way to access the data in these drives (if I have to build a server to access the drives it means I basically need to reinvest into a new desktop-like machine... right)?
Thanks for your help...

So I tried a new switch and still does not work.
At this point should I try to change the CPU? Or could it be something else? If both my old MoBO and the one I bought refurbished were shot, the computer would not boot every now and then would it? Sounds like there is a short somewhere in my install. This is happening even without the DDRAM or graphics card connected - only the CPU and Mobo... This seems like a problem Dr House should try to solve...
