Hey all,

I have an older PC that was having random restarts and lockups.  The machine was running slow so I bought a SSD to replace my old hard drive and try to speed things up and resolve the problem but the problem persisted.  I thought maybe it was the video card so I swapped it out then the computer didn’t turn on at all.  So I thought, Ah Hah… It’s the PSU causing the problem.  I purchased a new EVGA SuperNOVA 750 G2 220-G2-0750-XR 80+ GOLD 750W to replace my old CORSAIR TX Series CMPSU-750TX 750W ATX12V v2.3 SLI Ready CrossFire Ready 80 PLUS BRONZE.  The PC boots up and then shuts off after a couple minutes.  Its either the power supply or something else (excessive heating) causing the problem.  I tried to install my CPU monitoring software but it doesn’t stay on long enough to get it installed.   I don’t want to mess with it any more for fear of ruining my new power supply.  Any suggestions?

 
Here is my PC Specs
EVGA E758-A1 3-Way SLI (x16/x16/x8) LGA 1366 Intel X58
Intel Core i7-960 Bloomfield Quad-Core 3.2 GHz LGA 1366 130W BX80601960 3
EVGA 896-P3-1257-AR GeForce GTX 260 Core 216 Superclocked Edition 896MB 448-bit GDDR3 PCI Express 2.0 x16 
OCZ Gold 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Low Voltage Desktop Memory Model OCZ3G1600LV6GK
WD Blue 500GB Internal SSD Solid State Drive - SATA 6Gb/s 2.5 Inch - WDS500G1B0A
Windows 7 Home

Thanks in advance.

 

Any overclock or XMP profile set in BIOS? Did you try to reset the BIOS using the physical CMOS reset button on the motherboard? Your clear CMOS button is a little red button located at the bottom of the board right below the last PCI slot. Press it with the computer shut down. Keep in mind, you'll lose boot priority settings or any hardware RAID settings if you have that set up, just giving that as my disclaimer. 

 
If clearing CMOS does not resolve your issues. Please try MEMTEST86 to ensure your RAM is working properly: http://www.memtest86.com/download.htm
Choose the format you prefer, bootable CD or USB. Once the media is created, boot into it instead of Windows. You may need to override your boot priorities in the BIOS to get it to start MEMTEST86.
Run the default test, and let it go through its paces. It may take a long time. Any errors found will show up on screen during the test.

 
Glad you got it resolved.
