Hey guys, I am at a complete loss here could I have some help please?

I've recently started playing more games and there is only one thing stopping me, and it's my CPU usage. I can run games like Arma 2, perfectly fine with no problems however if I went to play Battlefield 3 my CPU usage goes to 80% - 100% and my PC has a long beep, it doesn't end until I exit the game or my PC just crashes.

I always thought a game like Arma 2 would require more than Battlefield 3, and I've even tried running BF3 on lower settings but that doesn't help and I just get the same long beep. I recently cleaned my PC (Just today actually to try and fix the beep, thinking it may be overheating however that has not helped.) and before it was happened and still does. I am at a complete loss at what to do, I have no idea why it is beeping and crashing on me.

My CPU is a AMD Phenom II X4 975 3.60 GHz processor with 8 GB ram, Radeon HD 6700 graphics card.

Thank you for reading this, I can't think of anything else I can do. I have also looked at all my other processes going on when playing and are not taking up much.

Hmm... I've tried several different programs like Core Temp and CPUID HWMonitor and I am able to get every temperature except from the one I want, the CPU temp. I'm able to tell you that it's getting 121 watts however, that's what it says and my graphics card idle is 50°C and is at around 60-70°C during gaming. I cleaned my PC thoroughly a few days ago so the processor shouldn't really be overheating.

I can also mention that when in game, I can play it then it starts to beep and I can Alt + Tab out the game and it will stop almost instantly but when I go back in it starts again.

It may be a motherboard issue. Perhaps the power design is not giving sufficient power to the CPU when it needs it. Causing instability and overheating. I would recommend Using HWinfo or hWmonitor to see the motherboard temps and voltages while this is happening before changing anything in the BIOS

EDIT. I forgot to mention it may be a PSU issue as IMO the PSU is the most important part and if you do not have good clean power it can damge your CPU and other components

Ok so I downloaded HWinfo and the motherboard temperature stays at a static 36°C which I feel is wrong, however Northbridge (No idea what this means) goes up into the 80 - 90°C and I do not think this is good at all. There is a CPU reading just under that however that stays at a static temperature of 12°C which again, I think is incorrect.

I cleaned my power supply too, my PC parts are as clean as I first got them almost.

Sometimes these utilities can read a bit off on AMD. idk that is I could not get the correct readings on my Atlhlon II when I had it. Speedfan read my CPU was -3°C all the time...would be nice. What Motherboard and PSU do you have ?. I am at a loss right now but I may come across something in a bit.

My PSU... agh I can't remember and I don't have the box however it is a 550W one. My motherboard is 990FXA-UD3 (Not sure if this is correct, just writing whatever I see on the box) You've probably realised by now I'm not too good with computers.

That is a god MB. One of the most reviewed motherboards for the AM3+ socket. I imagine the power supply is fine too. Most newer ones ill shut down before frying your PC. The MB had has a good quality VRM. Just to make sure though that nothing is amiss in the BIOS you could go in the BIOS and load from the defaults , It may say; Load From Optimized Defaults, like my Asus MB.

Ok, I can try "Load From Optimized Defaults" or something similar to that, I really hope this issue gets solved. I am thinking if it is overheating that an extra fan blowing on the CPU will also help as I can mount a fan on the side. I was going to get one anyway just to keep it cooler through summer, so if this doesn't work I don't know what will.

A desk fan is a good cheap way to get more air and can cool down your PC. I have been using a honeywell turbo 22cm fan pointed at the side of my case, Lian LI is not very practical for how expensive they are. Down side is dust I have to clean more than I should without the fan. I got it for my old Athtlon II 240 PC. it got very hot. It was actually the PSU that killed that PC. I don't even remember the name of the power supply but it was a 300-350w generic PSU.

I think I've just been really stupid. I cleaned my PC out and I took off my heatsink on my processor and I saw some dried up gell or something on the bottom of it and I didn't take much notice of it, just thinking it was glue or something but I asked my friend why my PC is beeping and he said that it's overheating and he asked me when I took my heatsink off my processor if it was a bit sticky and I said no, so he said to replace the thermal paste.

Could something as small as just having dried up thermal paste be a problem?

Sorry about the late response. After reading through the other replies I can second that the thermal paste is bad like I stated in my first post.

I actually took apart my first computer when I was 10 and I ended up removing the heat-sync on our old P4 computer and it was dried out like crazy. I unfortunately bent a pin though during the process and didn't have a computer to play on anymore):
