Hi all,
When I load windows I get a black screen with:
E79821MS.IAO 07/27/2016
Intel® Core ™ i7-6700 CPU @ 3.40GHZ, SPeed 100.00x34=3400.00 MHz
DRAM Frequency for DDR4 2133 MHz (Dual Channel)
DRAM Size is 32768 MB
USB Device full: 1KBD, 1 MICE, 0 MASS, 0 HUBs
Detected ATA/ATAPI Devices...
SATA Port1: TOshiba DT01ACA200
SATA Port3: CT240BX200SSD1
All settings were reset to default values.
Press F1 to Run Setup
Press F2 to Continue
-----
PC Details:
MSI B150m Bazooka Motherboard
MSI Nvidia GTX960 4gb
Intel i7-6700 64-flake CPU
Crucial 32GB DDR4 @ 2133MHz
Libation Power 700w lxxx Plus PSU
-----
Here is a little history. I started getting the F1/F2 screen out of nowhere and would just press F2 to continue. After nearly a week that screen stopped showing up and all I got was a black screen, I would have to hit restart on the PC 1 or 2 times to become it to load windows. The appointment and time would sometimes change.
I did a clean install of win x, I changed the CMOS battery, I updated all drivers, I updated the boot preferences in BIOS so it boots to the SSD first (this was reset subsequently installing windows). It was fine for a solar day. Now I am dorsum to the Press F1/F2 screen every time I turn it on. The BIOS settings still have information technology booting to the SSD but sometimes the date/time is reset when windows loads.
CrystalDisk says my drive is in good health.
BurnInTest ran for 15 minutes with no errors.
I have no idea what to try at present. Would capeesh any help!
Thanks.

That F1 and F2 bulletin seems to be the typical message from BIOS when information technology gets corrupted somehow (CMOS bombardment bad?). But you said you had changed the CMOS battery so let's rule that 1 out. I would enter BIOS, set default or optimized defaults, and so check thoroughly every BIOS entry to see if something is changed/badly configured. Don't forget to save changes (probably F10) before exitting. Make sure the new CMOS bombardment is valid also and it's working properly.

did you lot check the voltage of the replacement cmos battery? three volts is proficient, two.8v or less is a bad battery.
I would verify with a volt meter yous didn't replace with a bad battery.

Thanks eLPuSHeR and mightywiz.
I'll reset my BIOS shortly... how do I know if something is inverse/badly configured?
I can confirm it is a 3V battery.
I have but realized that this F1/F2 screen only shows when I kickoff my PC after I accept turned the ability off on the wall (I do this every time I turn my reckoner off so my router turns off). I left it on concluding dark and when I turned on my PC this morning windows loaded just if I plow it off for even v minutes and try to start the PC information technology won't load (have tried multiple times today). Whatever ideas based off this?
Thanks again.

Hi, nonetheless indicative of a cmos battery issue, sometimes you purchase a battery that is new, however information technology has lost it'south ability to hold charge, all-time approach is to try another battery, exist sure to remove ALL power before doing anything with the computer, disconnect from the mains ability and hold the start button for a few sec'south to drain any remainder power.
Apart from this i would expect at the PSU, your calculator (from what you posted appears to exist 2-3 years former, the PSU is more probable four-5 years old, and never had a skilful reputation, PSU's are notoriously poorly specced in quasi "gaming " rigs.

I too had the aforementioned problem and I tried all but failed and ultimately I found out the problem source.
It is defintely RAM fault. I tried some software to check RAM but they said its OK. I cleaned both my RAM hinges with eraser (pensil eraser) thorough. I put one Ram (4gb) it bootes well and without the balck screetn and without F1 and F2 selection. I put another r am (4gb) estimator did not boot. I was thinking of buying one slice of ram next day. Once again I tried by recleaning the RAM and lo the figurer booted but of course the balck screen with F1 and F2 is still in that location and my computer works fine well.
Conclusion: Replace ram and ur problem is solved.

From the description of the F1 F2 prompt merely appearing after the power is turned off at the wall, information technology is nearly certainly a bad CMOS 3V Battery - OR the battery holder/circuit.Have you really checked the actual voltage of the battery using a voltmeter?
Have yous checked that you are installing it correctly in the battery holder, and that information technology does non have any aptitude or damaged contacts?
