I am finally admitting defeat as I am not computer savvy and feel I might make the issue worse.
Not too long ago my PC started locking up. I would reset it and shrug it off. It would lock up during playing a game and sometimes randomly at any time.
The next issue that came was my PC would get zero beeps and not post upon resetting after it would crash.
If I let my PC sit, turned off for about 15-30 minutes, I could get it to POST and go to desktop.
So I decided to grab a new PSU, 750w to replace my old 750w. I test right away by playing a game, sure enough it froze within 20 minutes.
I watch my temps a lot and my CPU will sit around 34 idle and around 50 when stressed. My GPU idles around 30 and can reach temps up to around 50 as well. Nothing ever extreme or dangerous, temp wise.
After some googling, I noticed a lot of people that had similar problems were told that if it wasn't the PSU it could more than likely be the MOBO. Well, I replaced the mobo and now my PC does that awful loop where it trys to do windows startup repair and if you select to start windows normally it just restarts and takes you right back to startup repair. The computer also locked up in BIOS. The bios on my new board looks all fancy, not the old BIOS I am used to. I have not tinkered with any bios settings however.
I have 4 2gb sticks of G.Skill DDR3-1600.
I should of done this first, as I found out from researching that checking Ram is the first thing to do. I booted with just 1 stick in slot 1 and got it to post every time. Is it possible that a stick is worn out and fails when it heats up? Usually when other people did this they were able to weed out a faulty stick of ram. Or so it seemed.
My current specs are:
-Windows 7 64bit
-Phenom II x4 955 3.2
-8GB DDR3-1600 G.Skill
-ASUS M5A97 R2.0 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX AMD Motherboard with UEFI BIOS
-Rosewill 750w modular PSU
-Radeon 7850 GPU
-Western Digital 640gb Hard drive
I am going to have to find my Windows 7 disc. I'd really hate to rebuy Windows 7.
If I left anything out, let me know.
From your description, you have replaced the motherboard - which would necessitate doing a repair installation of your Windows (driver issues) unless the mobo is the exact make/model (and even then, it still may be necessary as the mobo can have different components used over time).
The second issue may be your RAM. My suggestion would be to use only 1 RAM stick, and attempt the Windows Repair option. After repair completes, you can add one stick at a time to make sure there are no issues with the RAM. If you detect any issues with the RAM - I would suggest buying an 8GB stick of RAM to replace them ($40-$60). Make sure your BIOS settings are to "Failsafe Defaults" (no overclocking/enhanced settings).
